System Integration Precautions  
The following precautions are provided as general guidelines for the setup of the ASD within the  
system.  
The Toshiba ASD is a general-purpose product. It is a system component only and the system  
design should take this into consideration. Please contact your Toshiba sales representative for  
application-specific information or for training support.  
The Toshiba ASD is part of a larger system and the safe operation of the ASD will depend on  
observing certain precautions and performing proper system integration.  
A detailed system analysis and job safety analysis should be performed by the systems designer  
and/or systems integrator before the installation of the ASD component. Contact your Toshiba sales  
representative for options availability and for application-specific system integration information if  
required.  
Personnel Protection  
Installation, operation, and maintenance shall be performed by Qualified Personnel Only.  
A thorough understanding of the ASD will be required before the installation, operation, or  
maintenance of the ASD.  
WARNING  
Rotating machinery and live conductors can be hazardous and shall not come into contact with  
humans. Personnel should be protected from all rotating machinery and electrical hazards at all  
times.  
Insulators, machine guards, and electrical safeguards may fail or be defeated by the purposeful or  
inadvertent actions of workers. Insulators, machine guards, and electrical safeguards are to be  
inspected (and tested where possible) at installation and periodically after installation for potential  
hazardous conditions.  
Do not allow personnel near rotating machinery. Warning signs to this effect shall be posted at or  
near the machinery.  
Do not allow personnel near exposed electrical conductors. Human contact with electrical  
conductors can be fatal. Warning signs to this effect shall be posted at or near the hazard.  
Personal protection equipment shall be provided and used to protect employees from any hazards  
inherent to system operation.

W7 ASD Installation and Operation Manual  
     
System Setup Requirements  
When using the ASD as an integral part of a larger system, it is the responsibility of the ASD  
installer or maintenance personnel to ensure that there is a fail-safe in place, i.e., an arrangement  
designed to switch the system to a safe condition if there is a fault or failure.  
System safety features should be employed and designed into the integrated system in a manner  
such that system operation, even in the event of system failure, will not cause harm or result in  
personnel injury or system damage (i.e., E-Off, Auto-Restart settings, System Interlocks, etc.).  
The programming setup and system configuration of the ASD may allow it to start the motor  
unexpectedly. A familiarity with the Auto-restart and the Remote/Local settings and function is a  
requirement to use this product.  
Improperly designed or improperly installed system interlocks may render the motor unable to start  
or stop on command.  
The failure of external or ancillary components may cause intermittent system operation (i.e., the  
system may start the motor without warning).  
There may be thermal or physical properties, or ancillary devices integrated into the overall system  
that may allow for the ASD to start the motor without warning. Signs to this effect must be posted  
at the equipment installation site and near the driven equipment.  
If a secondary magnetic contactor (MC) is used between the ASD output and the load, it should be  
interlocked to halt the ASD before the secondary contact opens. If the output contactor is used for  
bypass operation, it must be interlocked such that commercial power is never applied to the ASD  
output terminals (U, V, W).  
Power factor improvement capacitors or surge absorbers must not be installed on the output of the  
ASD.  
Use of the built-in system protective features is highly recommended (i.e., E-Off, Overload  
Protection, etc.).  
The operating controls and system status indicators should be clearly readable and positioned  
where the operator can see them without obstruction.  
Additional warnings and notifications shall be posted at the equipment installation location as  
deemed required by Qualified Personnel.  
Follow all warnings and precautions and do not exceed equipment ratings.

Operational and Maintenance Precautions  
WARNING  
Turn off, lockout, and tagout the main power, the control power, and instrumentation connections  
before inspecting or servicing the drive, or opening the door of the enclosure.  
Turn off, lockout, and tagout the main power, the control power, and instrumentation connections  
before proceeding to disconnect or connect the power wiring to the equipment.  
The capacitors of the ASD maintain a residual charge for a period of time after turning the ASD off.  
The required time for each ASD typeform is indicated with a cabinet label and a Charge LED.  
Wait for at least the minimum time indicated on the enclosure-mounted label and ensure that the  
Charge LED has gone out before opening the door of the ASD once the ASD power has been  
turned off.  
Turn the power on only after attaching (or closing) the front cover and Do Not remove the front  
cover of the ASD when the power is on.  
Do Not attempt to disassemble, modify, or repair the ASD. Call your Toshiba sales representative  
for repair information.  
Do not place any objects inside of the ASD.  
If the ASD should emit smoke or an unusual odor or sound, turn the power off immediately.  
The heat sink and other components may become extremely hot to the touch. Allow the unit to cool  
before coming in contact with these items.  
Remove power from the ASD during extended periods of non-use.  
The system should be inspected periodically for damaged or improperly functioning parts,  
cleanliness, and to ensure that the connectors are tightened securely.  
Ensure that the Run functions (F, R, Preset Speed, etc.) of the ASD are off before performing a  
Reset. The post-reset settings may allow the ASD to start unexpectedly.  
Retry or Reset settings may allow the motor to start unexpectedly. Warnings to this effect should  
be clearly posted near the ASD and the motor.  
In the event of a power failure, the motor may restart after power is restored.  
Follow all warnings and precautions and do not exceed equipment ratings.  
DO NOT install, operate, perform maintenance, or dispose of this equipment until you have read and  
understood all of the product warnings and user directions. Failure to do so may result in equipment  
damage, operator injury, or loss of life.

W7 ASD Installation and Operation Manual  
       
Motor Characteristics  
Listed below are some variable speed AC motor control concepts with which the user of the  
W7 Adjustable Speed Drive should become familiar.  
Pulse Width Modulation Operation  
The W7 ASD uses a sinusoidal Pulse Width Modulation (PWM) control system. The output current  
waveform generated by the ASD approaches that of a perfect sine wave; however, the output waveform  
is slightly distorted. For this reason, the motor may produce more heat, noise, and vibration when  
operated by an ASD, rather than directly from commercial power.  
Overload Protection Adjustment  
The W7 ASD software monitors the output current of the system and determines when an overload  
condition occurs. The overload current level is a percentage of the rating of the motor. This function  
protects the motor from overload.  
The default setting for the overload detection circuit is set to the maximum rated current of the ASD at  
the factory. This setting will have to be adjusted to match the rating of the motor with which the ASD is  
to be used. To change the overload reference level, see Electronic Thermal Protection #1 on pg. 70.  
Power Factor Correction  
DO NOT connect a power factor correction capacitor or surge absorber to the output of the ASD.  
If the ASD is used with a motor that is equipped with a capacitor for power factor correction, remove  
the capacitor from the motor.  
Connecting either of these devices to the output of the ASD may cause the ASD to malfunction and trip,  
or the output device may cause an over-current condition resulting in damage to the device or the ASD.  
Light Load Conditions  
When a motor is operated under a continuous light load (i.e., at a load of less than 50% of its rated  
capacity) or it drives a load which produces a very small amount of inertia, it may become unstable and  
produce abnormal vibration or trips because of an over-current condition. In such a case, the carrier  
frequency may be lowered to compensate for this undesirable condition (see Program  
Special  
Note: For proper operation, the carrier frequency must be 2.2 kHz or above except when  
operating in the Constant Torque or Variable Torque modes.  
Load-produced Negative Torque  
When the ASD is used with a load that produces negative torque (an overhauling load), the over-voltage  
or over-current protective functions of the ASD may cause nuisance tripping.  
To minimize the undesirable effects of negative torque the dynamic braking system may be used. The  
dynamic braking system converts the regenerated energy into heat that is dissipated using a braking  
W7 ASD Installation and Operation Manual  
11  
                       
resistor. The braking resistor must be suitably matched to the load. Dynamic braking is also effective in  
reducing the DC bus voltage during a momentary over-voltage condition.  
CAUTION  
If under extreme conditions the dynamic braking system or a component of this system were to fail, the  
dynamic braking resistor may experience an extended over-current condition. The DBR circuit was  
designed to dissipate excessive amounts of heat and if the extended over-current condition were allowed  
to exceed the circuit parameters, this condition could result in a fire hazard.  
To combat this condition, the 3-phase input may be connected using contactors that are configured to  
open in the event of an extended DBR over-current condition or an internal circuit failure. Using a  
thermal sensor and/or overload protection as the 3-phase input contactor drive signal, the contactors will  
open and remove the 3-phase input power in the event of an extended DBR over-current or system over-  
voltage condition.  
Motor Braking  
The motor may continue to rotate and coast to a stop after being shut off due to the inertia of the load. If  
an immediate stop is required, a braking system should be used. The two most common types of motor  
braking systems used with the W7 ASD are DC Injection Braking and Dynamic Braking.  
For further information on braking systems, see DC Injection Braking Current on pg. 65 and  
ASD Characteristics  
Over-current Protection  
Each W7 ASD model was designed for a specified operating power range. The ASD will incur a trip if  
the design specifications are exceeded.  
However, the ASD may be operated at 100% of the specified output-current range continuously or at  
120% for a limited time as indicated in the section titled Current/Voltage Specifications on pg. 155.  
Also, the Overcurrent Stall Level setting may be adjusted to help with nuisance over-current trips.  
When using the ASD for an application that controls a motor which is rated significantly less than the  
maximum current rating of the ASD, the over-current limit (Thermal Overload Protection) setting will  
have to be changed to match the application. For further information on this parameter, see Electronic  
ASD Capacity  
The W7 ASD must not be used with a motor that has a significantly larger capacity, even if the motor is  
operated under a small load. An ASD being used in this way will be susceptible to a high-output peak  
current which may result in nuisance tripping.  
Do not apply a level of input voltage to an ASD that is beyond that which the ASD is rated. The input  
voltage may be stepped down if required with the use of a step-down transformer or some other type of  
voltage-reduction system.

W7 ASD Installation and Operation Manual  
               
Installation and Connections  
The W7 Adjustable Speed Drive may be set up initially by performing a few simple configuration  
settings. To operate properly, the ASD must be securely mounted and connected to a power source (3-  
phase AC input at the L1/R, L2/S, and L3/T terminals). The control terminals of the ASD may be used  
by connecting the terminals of the Control Terminal Strip to the proper sensors or signal input sources  
(see the section titled I/O and Control on pg. 17).  
The output terminals of the ASD (T1/U, T2/V, and T3/W) must be connected to the motor that is to be  
controlled (see Figure 17 on pg. 24).  
As a minimum, the installation of the ASD shall conform to Article 110 of the 2005 NEC, the  
Occupational Safety and Health Administration requirements, and to any other local and regional  
industry codes and standards.  
Installation Notes  
When a brake-equipped motor is connected to the ASD, it is possible that the brake may not release at  
startup because of insufficient voltage. To avoid this, Do Not connect the brake or the brake contactor to  
the output of the ASD.  
If an output contactor is used for bypass operation, it must be interlocked such that commercial power is  
never applied to the output terminals of the ASD (T1/U, T2/V, or T3/W).  
If a secondary magnetic contactor (MC) is used between the output of the ASD and the motor, it should  
be interlocked such that the ST – CC connection is disconnected before the output contactor is opened.  
Do Not open and then close a secondary magnetic contactor between the ASD and the motor unless the  
ASD is off and the motor is not rotating.  
Note: Re-application of power via a secondary contact while the ASD is on or while the  
motor is still turning may cause ASD damage.  
On some devices the ST-to-CC connection is further enhanced by the operation of the MS1 AUX relay  
circuit. The MS1 AUX relay circuit is normally open and closes the ST-to-CC connection (via ST1)  
only after normal system power is available. The MS1 AUX relay circuit prohibits the ST-to-CC  
connection in the event that the MS1 contactor fails to close during start up or if MS1 opens while the  
ASD is running. For the 460 volt ASD this feature is available on the 75 HP and above systems.  
Figure 2. Alternative ST activation using the MS1 AUX circuit configuration.  
The ASD input voltage should remain within 10% of the specified input voltage range. Input voltages  
approaching the upper or lower limit settings may require that the overvoltage and undervoltage stall  
protection level parameters be adjusted. Voltages outside of the permissible tolerance should be  
avoided.  
The frequency of the input power should be ±2 Hz of the specified input frequency.  
Do not use an ASD with a motor that has a power rating that is higher than the rated output of the ASD.

13  
           
The ASD is designed to operate NEMA B motors. Consult with your sales representative before using  
the ASD for special applications such as with an explosion-proof motor or applications with a piston  
load.  
Do Not apply commercial power to the output terminals T1/U, T2/V, or T3/W.  
Disconnect the ASD from the motor before megging or applying a bypass voltage to the motor.  
Interface problems may occur when an ASD is used in conjunction with some types of process  
controllers. Signal isolation may be required to prevent controller and/or ASD malfunction (contact  
your Toshiba sales representative or the process controller manufacturer for additional information  
about compatibility and signal isolation).  
Use caution when setting the output frequency. Over speeding a motor decreases its ability to deliver  
torque and may result in damage to the motor and/or the driven equipment.  
All W7 ASDs are equipped with internal DC bus fuses. However, not all W7 ASDs are equipped with  
internal primary power input fuses (HP-dependent).  
Mounting the ASD  
CAUTION  
Install the unit securely in a well ventilated area that is out of direct sunlight using the mounting holes  
on the rear of the ASD.  
The ambient temperature rating for the W7 ASD is from 14 to 104° F (-10 to 40° C). The process of  
converting AC to DC, and then back to AC produces heat. During normal ASD operation, up to 5% of  
the input energy to the ASD may be dissipated as heat. If installing the ASD in a cabinet, ensure that  
there is adequate ventilation.  
Do Not operate the ASD with the enclosure door open or removed.  
Note: Ensure that the ventilation openings are not obstructed.  
ASDs produce high-frequency noise — steps must be taken during installation to avoid the negative  
effects of noise. Listed below are some examples of measures that will help to combat noise problems.  
Separate the input and output power conductors of the main circuit. Do not install the input and  
output wires in the same duct or in parallel with each other, and do not bind them together.  
Do not install the input or output power conductors of the main circuit and the wires of the control  
circuit in the same duct or in parallel with each other, and do not bind them together.  
Use shielded wires or twisted wires for the control circuits.  
Ensure that the grounding terminals (G/E) of the ASD are securely connected to ground.  
Connect a surge suppressor to every electromagnetic contactor and every relay installed near the  
ASD.  
Install noise filters as required.

DANGER  
Refer to the section titled Installation Precautions on pg. 5 and the section titled Lead Length  
Specifications on pg. 16 before attempting to connect the ASD and the motor to electrical power.  
System Grounding  
Proper grounding helps to prevent electrical shock and to reduce electrical noise. The ASD is designed  
to be grounded in accordance with Article 250 of the 2005 NEC or Section 10/Part One of the  
Canadian Electrical Code (CEC).  
The grounding conductor shall be sized in accordance with Article 250-122 of the 2005 NEC or Part  
One-Table 6 of the CEC.  
Note: The metal of conduit is not an acceptable ground.  
The input power, output power, and control lines of the system shall be run in separate metal conduits  
and each shall have its own ground conductor.  
Power Connections  
DANGER  
Connect the 3-phase input power to the input terminals of the W7 ASD at L1/R, L2/S, and L3/T.  
Connect the output terminals T1/U, T2/V, and T3/W of the W7 ASD to the motor.  
The input and output conductors and terminal lugs used shall be in accordance with the specifications  
listed in the section titled Cable/Terminal Specifications on pg. 154.  
An inductor may be connected across terminals PA and PO to provide additional filtering. When not  
used, a jumper must be connected across these terminals (see Figure 17 on pg. 24).  
Connect the input and output power lines of the W7 ASD as shown in Figure 3.  
Install a molded case circuit breaker (MCCB) or fuse between the 3-phase power source and the W7  
ASD in accordance with the fault current setting of the ASD and 2005 NEC Article 430.  
Note: In the event that the motor rotates in the wrong direction when powered up, reverse  
any two of the three ASD output power leads connected to the motor.

W7 ASD Control  
The Control PCBA (P/N 56000) serves as the primary control source for the W7 ASD and receives  
input from the Control Terminal Strip PCBA, an Option Card, RS232/RS485 Communications, or the  
W7 ASD Keypad.  
The Control PCBA has been enhanced to support two new functions: Multiple Protocol  
Communications and the ability to communicate in either half- or full-duplex modes.  
Using the optional multiple-protocol communications interface: the ASD-NANOCOM, the Control  
PCBA may be configured for the type of communications protocol being received and respond  
appropriately to the sending device. The ASD-NANOCOM connects to the J4 and J5 connectors  
(see Figure 6). A jumper PCBA (P/N 55365) is required at the J4 connector if not using the ASD-  
NANOCOM.  
The ASD-NANOCOM must be setup to support the desired communications protocol via Program  
Comm Settings. Consult the ASD-NANOCOM User’s Manual (P/N 10572-1.000-000) for a complete  
listing of the setup requirements.  
Half or Full duplex communications is available when using RS232/RS485 communications. The  
jumpers at the JP1 and the JP2 connectors may be moved from one position to the other to facilitate  
either half- or full-duplex operation. If no jumpers are used the system will operate in the full duplex  
mode.

W7 ASD Installation and Operation Manual  
   
Electronic Operator Interface  
The W7 ASD Electronic Operator Interface (EOI) is comprised of an LCD display, two LEDs, a rotary  
encoder, and eight keys. These items are described below and their locations are provided in  
The EOI can be mounted remotely from the ASD as described in the section titled EOI Remote Mounting  
on pg. 27. The dimensional requirements for remote mounting may also be found there. Using a screw  
length that exceeds the specified dimensions may cause deformation of the outer surface of the bezel as  
shown in Figure 21 on pg. 29 and should be avoided.  
The interface can operate up to distances of 15 feet from the ASD via the Common Serial (TTL) Port. For  
distances beyond 15 feet, the RS232/RS485 port is recommended.  
EOI Features  
LCD Display — Displays configuration information, performance data (e.g., motor frequency, bus  
voltage, output power, etc.), and diagnostic information.  
Local|Remote Key — Toggles the system to and from the Local and Remote modes. The LED is on  
when the system is in the Local Command mode. The Local|Remote Key may be switched between the  
Local and Remote modes while at the Frequency Command screen only.  
The Local Command mode enables the Command and Frequency control functions to be carried out  
via the EOI.  
The Remote mode enables the Command and Frequency control functions to be carried out via any  
one of the following methods:  
Pulse Input,  
Motorized Pot,  
Communication Card,  
RS232/RS485,  
Common TTL,  
Binary/BCD,  
LED Keypad,  
Option Card RX2,  
RX,  
RR, or  
VI/II.  
The input channel selection may be made via Program Utilities Command and Frequency  
Settings.  
Enter Key — Selects a menu item to be changed or accepts and records the changed data of the selected  
field (same as pressing the Rotary Encoder).  
Esc Key — Returns to the previous level of the menu tree, toggles between the Communication  
Command and the Frequency Command screens, or cancels changes made to a field if pressed while  
still in the reverse video mode (dark background/light text). The 3 functions are menu-specific.  
Run Key — Issues the Run command while in the Local mode. A Run command issued from the EOI  
while in the Remote mode will be activated once the Local mode is selected and the motor will run at the  
commanded speed.  
Run Key Status LED — Illuminates green while stopped or red while running.  
Stop Key — If pressed once while in the Local mode issues the Off command and decelerates the motor  
at the programmed rate until it stops. If pressed twice in rapid succession initiates an Emergency Off  
(terminates the ASD output and applies the brake if so configured) from the Local or Remote modes.

EOI Operation  
The EOI is the primary input/output device for the user. The EOI may be used to monitor system  
functions, input data into the system, or perform diagnostics.  
Note: The Up/Down arrow keys and the Enter key may be used to perform the functions of the  
Rotary Encoder. The Rotary Encoder will be used in this explanation and throughout  
this manual for the Up, Down, and Enter key functions.  
The software used with the W7 ASD is menu driven; thus, making it a select and click environment. The  
operating parameters of a motor may be selected and viewed or changed using the EOI.  
To change a parameter setting, go to the Program mode by pressing the MON/PRG key until the  
Program menu is displayed. Turn the Rotary Encoder until the desired parameter group is within the  
cursor block. Press the Rotary Encoder (repeat if there is a submenu).  
The selection will take on the reverse video format (dark background/light text). Turn the Rotary  
Encoder to change the value of the parameter. Press the Esc key while the display is in the reverse video  
mode to exit the menu without saving the change or press the Rotary Encoder to accept the new setting.

W7 ASD Installation and Operation Manual  
             
EOI Remote Mounting  
The W7 ASD may be controlled from a remotely-mounted EOI. For safety and application-specific  
reasons, some ASD installations will warrant that the operator not be in the vicinity during operation or  
that the EOI not be attached to the ASD housing. The EOI may be mounted either with or without the  
optional W7 ASD Remote Mounting Kit (P/N ASD-MTG-KIT). The ease of installation is enhanced by  
the W7 ASD Remote Mounting Kit which allows for easier cable routing and EOI placement.  
The EOI can operate up to distances of 15 feet from the ASD via the Common Serial (TTL) Port. For  
distances beyond 15 feet, the RS232/RS485 port is recommended.  
Remote mounting will also allow for multiple EOI mountings at one location if controlling and  
monitoring several ASDs from a central location is required.  
The optional dust cover (P/N ASD-BPC) may be used to cover the front panel opening of the ASD  
housing after removing the EOI. An EOI extender cable is required for remote mounting. EOI extender  
cables are available in lengths of 7, 10, or 15 feet and may be ordered through your sales representative.

EOI Installation Precautions  
Install the unit securely in a well ventilated area that is out of direct sunlight using the four mounting holes  
of the EOI. The ambient temperature rating for the EOI is 14 to 104° F (-10 to 40° C).  
Select a mounting location that is easily accessible by the user.  
Avoid installation in areas where vibration, heat, humidity, dust, metal particles, or high levels of  
electrical noise (EMI) are present.  
Do not install the EOI where it may be exposed to flammable chemicals or gasses, water, solvents, or  
other fluids.  
Turn the power on only after securing the front cover to the ASD.

W7 ASD Direct Access/Communication Numbers  
The W7 ASD has the ability to allow the user direct access to the motor control functions. The functions  
listed below have an associated Parameter Number which accesses its setting. There are three ways in  
which the motor-control parameters may be accessed for modification: Program applicable menu path,  
Program  
Direct Access  
applicable parameter number, or via Communications (see the 7-Series  
Serial Communications User Manual for further information on communications protocol). Once  
accessed, the parameter may be viewed or changed.  
The Program mode allows the user to develop an application-specific motor control profile. Motor  
control functions may be set to accommodate specific power and timing requirements for a given  
application. The configurable parameters of the Program mode that have user-accessible Parameter  
Numbers are listed and described below.  
Note: The setup procedures included within this section may require a Reset before performing the  
procedure. Application-specific settings may then be performed. The pre-Reset conditions may be  
saved (see Save User Parameters).

Program  
Fundamental Parameters  
Fundamental #1 Accel  
Parameter Type — Numerical  
Time #1  
Factory Default — (ASD-dependent)  
Changeable During Run — Yes  
Minimum — 0.1  
This parameter specifies the programmed time in seconds for the output of the  
ASD to go from 0.0 Hz to the Maximum Frequency for the #1 Acceleration  
profile. The accel/decel pattern may be set using Accel/Decel #1 Pattern. The  
minimum and maximum accel/decel time may be set using S-Pattern Lower  
Limit Adjustment and the S-Pattern Upper Limit Adjustment.  
Maximum — 6000  
Units — Seconds  
Note: An acceleration time shorter than the load will allow may  
cause nuisance tripping and mechanical stress to loads.  
Automatic Accel/Decel and Stall settings may lengthen the  
acceleration time.  
Acceleration  
The acceleration rate of a motor is determined by several factors: applied  
power, applied load, and the physical properties of the motor (winding  
parameters, motor size, etc.). The ASD will control the first of these factors:  
input power. The settings of the ASD control the frequency and amplitude of  
the applied voltage to the motor.  
Under most operating conditions, as the output frequency of the ASD goes up  
so does the output voltage (linear acceleration). The ASD has the ability to  
modify the relationship between frequency and voltage automatically to  
produce smoother operation or increased (starting) torque.

Program  
Time #2  
Fundamental Parameters  
Fundamental #2 Accel

Changeable During Run — Yes  
Minimum — 0.1  
This parameter specifies the programmed time in seconds for the output of the  
ASD to go from 0.0 Hz to the Maximum Frequency for the #2 Acceleration  
profile. The accel/decel pattern may be set using Accel/Decel #2 Pattern. The  
minimum and maximum accel/decel time may be set using S-Pattern Lower  
Limit Adjustment and the S-Pattern Upper Limit Adjustment.  
Maximum — 6000  
Units — Seconds  
This setting is also used to determine the acceleration rate of the Motorized Pot  
function.  
Note: An acceleration time shorter than the load will allow may  
cause nuisance tripping and mechanical stress to loads.  
Automatic Accel/Decel and Stall settings may lengthen the  
acceleration time.

S-pattern 1 is used for applications that  
require quick acceleration and deceleration.  
This setting is also popular for applications that  
require shock absorption at the start of  
acceleration or deceleration.  
S-pattern 2 acceleration and deceleration  
decreases the rate of change above the base

Factory Default — Output Current  
This setting determines the output function of the AM analog output terminal.  
This output terminal produces an output current that is proportional to the  
magnitude of the function assigned to this terminal. The available assignments  
for this output terminal are listed in Table 8 on page 142.  
Changeable During Run — Yes  
Note: To read voltage at this terminal a 100 – 500resistor is  
required and must be connected from AM (+) to AM (-). The  
voltage is read across the 100 – 500resistor.  
Current may be read by connecting an ammeter from AM (+)  
to AM (-).  
The AM analog output has a maximum resolution of 1/1024. The AM

This parameter sets the percentage of the rated current of the ASD that will be

DC Injection Braking  
DC Injection Braking is a braking system used with three-phase motors.  
Unlike conventional brakes, there is no physical contact between the rotating  
shaft and a stationary brake pad or drum. When braking is required, the ASD  
outputs a DC current that is applied to the windings of the motor to quickly  
brake the motor. The braking current stops when the time entered in DC  
Injection Braking Time times out.  
Maximum — 100.00  
Units — %  
The intensity of the DC current used while braking determines how fast the  
motor will come to a stop and may be set at the DC Injection Braking  
Current parameter. The intensity setting is entered as a percentage of the full  
load current of the ASD.  
Note: DC Injection Braking is also used to preheat the motor or to  
keep the rotor from spinning freely when no rotation is  
required by providing a pulsating DC current into the motor  
at the Carrier Frequency. This feature may be enabled at the  
Motor Shaft Stationary Control parameter.

Dynamic Braking  
Dynamic Braking uses the inertial energy of the load to produce a braking  
force or it may be used to reduce the bus voltage in an attempt to preclude an  
overvoltage trip during deceleration. The inertial energy of the load drives the  
rotor and induces a current into the stator of the motor.  
The induced stator current (energy) is dissipated through a resistive load. The  
resistive load is connected across terminals PA and PB (non-polarized). Using a  
low-value, high-wattage resistance as a load for the generated current, the  
resistive load dissipates the induced energy. The dissipated energy is the energy  
that would otherwise have caused the rotor to continue to rotate.  
Dynamic Braking helps to slow the load quickly; it cannot act as a holding  
brake.  
The Dynamic Braking function may be setup and enabled by connecting a  
braking resistor from terminal PA to PB of the ASD and providing the proper  
information at the DBR parameters: Dynamic Braking Resistor (DBR)

If Freq Source #1 is selected here, the ASD will follow the speed command of  
the Freq Mode #1 selection. If Freq Source #2 is selected here, the ASD will  
follow the speed command of the Freq Mode #2 selection.  
The Freq #1 Priority and Freq #2 Priority selections are used in conjunction  
with the Mode #1/#2 SW (Switching) Freq parameter setting. The Mode #1/

Soft Stall Selection  
Parameter Type — Selection List  
Factory Default — Trip Only  
Changeable During Run — No  
This parameter Enables/Disables the Soft Stall and Overload Trip functions.  
The Soft Stall function reduces the output frequency of the ASD when the  
current requirements of the motor exceed the Thermal Protection #1 setting;  
thus, reducing the output current.  
If the current drops below the Thermal Protection #1 level setting within a  
specified time, the output of the ASD will accelerate to the programmed  
frequency setpoint.  
If the current does not drop below the Thermal Protection #1 level setting  
within the specified time, a trip will be incurred if the Trip function is enabled  
at this parameter.  
Soft Stall is highly effective in preventing motor overload trips when used on  
fans, blowers, pumps, and other centrifugal loads which require less torque at  
lower frequencies.  
This parameter may be configured for a V/f motor or a standard motor.  
Note: The Soft Stall setting may affect acceleration times and  
patterns.

until the Upper Limit is reached. The Frequency Mode setting must be set to Motorized Pot. Simulation. The MOP  
acceleration rate is determined by the Accel #2 Time setting.  
Motorized Pot Down (MOP) — Activating this terminal causes a decrease in motor speed for the duration of the connection  
until the Lower Limit is reached. The Frequency Mode setting must be set to Motorized Pot. Simulation. The MOP  
deceleration rate is determined by the Decel #2 Time setting.  
Motorized Pot Clear — Activating this terminal will establish a frequency setpoint of 0.0 Hz after a power down or a system  
reset regardless of the Motorized Pot Frequency at Power Down setting. The Motorized Pot Clear terminal must be  
activated before the initiation of the power down or reset.  
Momentary (Push) Run — When activated this terminal starts the motor.  
Momentary (Push) Stop — When activated this terminal stops the motor.  
Forward/Reverse — This setting operates in conjunction with another discrete terminal being set to the Run/Stop function.  
When configured to Run (Run/Stop activated), the activation/deactivation of this terminal toggles the direction of the motor.  
Run/Stop — This terminal enables the motor to run when connected to CC and disables the motor when the connection is  
broken.  
Line (Power) Bypass — Terminal activation of the Line (Power) Bypass function requires an enable at the Power  
Switching parameter and a user-supplied switching frequency at the Power Switching Frequency parameter.  
During acceleration, once the Power Switching Frequency setting is reached, activating this terminal switches off the ASD  
output and routes commercial power to the motor. If At Frequency is selected at the Power Switching parameter, Line  
(Power) Bypass will be carried out once reaching the user-supplied switching frequency and activating this terminal will  
serve no function.  
Frequency Priority — Activating this terminal toggles the frequency control between the Frequency Mode (#1) setting and  
the setting of Frequency Mode #2. This function is enabled by setting the Ref Priority Sel to Freq Prty Switch and is  
located at Program Freq Settings

VI/II Prty (VI/II Terminal Priority) — Activating this terminal assigns command control to the VI/II Terminal and  
overrides all other Control Terminal Strip input so long as the Command Mode is set to Use Control Terminal Strip.  
Term Prty (Terminal Strip Priority) — Activating this terminal overrides the Frequency Mode setting and assigns speed  
control to the Control Terminal Strip.  
Editing Enabled (LED) — The LED Keypad system is unavailable at the time of this release.  
Torque/Position (Control Switch) — This function allows for a system change from speed-control to torque- or position-  
control as a function of the V/f setting when activated.  
Deviation Counter Clear — Activating this terminal clears the Deviation Counter when operating in the Position Control  
mode.  
Forward Limit (Position Control) — Activating this terminal will immediately stop the ASD and hold its position. If the  
connection remains for an extended period the ASD will time out and trip. This function is normally used for over-travel  
conditions.  
Reverse Limit (Position Control) — Activating this terminal will immediately stop the ASD and hold its position. If the  
connection remains for an extended period the ASD will time out and trip. This function is normally used for over-travel  
conditions.  
Light-Load High-Speed Enable — Activating this terminal sets the lower limit of an output frequency range in which the  
Light-load/High-speed function may be used.  
Snap Stop Control Enable — TBD.  
Pre-excite (Motor) — Activating this terminal applies an excitation current to the motor (holds shaft stationary) for the  
duration of the activation.  
Brake Command — TBD.  
Brake Release — Activating this terminal initiates the brake release command. This setting requires that another discrete  
input terminal be set to System Consistent Sequence (BA: braking answer) to complete the brake release command and to  
convey the status of the braking system to the user or to a dependent subsystem.  
Once the braking release function is initiated, the Brake Fault Time begins to count down. Should the count-down timer  
expire before the brake releases or before the Braking Answer is returned, fault E-11will occur. Otherwise, the brake releases  
the motor and normal motor operations resume.  
The Braking Release function is primarily used at startup; but, may be used when the brake is applied while the motor is  
running.  
Brake Answer — This setting is required when the Braking Release function is used. The function of this input terminal is  
to receive the returned the status of the braking system. The returned status is either Released or Not Released.  
If Released is returned within the time setting of the Brake Fault Time parameter, normal system function resumes.  
If Not Released is returned or if the Brake Fault Time parameter setting times out before either signal is returned, then fault  
E-11 occurs.  
The returned signal may also be used to notify the user or to control a dependent subsystem.  
Brake Test — TBD.  
Fire Speed — When activated Preset Speed #1 is output from the ASD.  
MUV Disable — When activated the Main Undervoltage Detect function is disabled.

Alarms, Trips, and Troubleshooting  
Alarms and Trips  
This section lists the available user-notification codes of the EOI display and provides information that  
assists the user in the event that a Fault is incurred. The User Notification codes are displayed as an  
indication that a system function or system condition is active (i.e., ATN, DB, and DBON). The code is  
displayed on the EOI for the duration of the activation.  
If a user setting or an ASD parameter has been exceeded, or if a data transfer function produces an  
unexpected result, a condition that is referred to as a Fault is incurred.  
An Alarm is an indication that a Fault is imminent if existing operating conditions continue unchanged.  
An Alarm may be associated with an output terminal to notify the operator of the condition remotely,  
close a contact, or engage a brake. At the least, an Alarm will cause an alarm code to appear on the EOI  
display. Table 11 on pg. 147 lists the 15 possible Alarm codes that may be displayed during operation of  
the W7 ASD.  
In the event that the condition that caused the Alarm does not return to its normal operating level within a  
specified time, the ASD Faults and a Trip is incurred (Fault and Trip are sometimes used  
interchangeably). A Trip is a safety feature, and is the result of a Fault, that disables the ASD system in  
the event that a subsystem of the ASD is malfunctioning, or one or more of the variables listed below  
exceeds its normal range (time and/or magnitude).  
• Current,  
Voltage,  
• Speed,  
• Temperature,  
• Torque, or  
• Load.  
See Table 13 on pg. 149 for a listing of the potential Trips and the associated probable causes.  
The operating conditions at the time of the trip may be used to help determine the cause of the trip. Listed  
below are operating conditions that may be used to assist the operator in correcting the problem or that the  
ASD operator should be prepared to discuss when contacting Toshiba’s Customer Support for assistance.  
• What trip information is displayed?  
• Is this a new installation?  
• Has the system ever worked properly and what are the recent modifications (if any)?  
• What is the ASD/Motor size?  
• What is the CPU version and revision level?  
• What is the EOI version?  
• Does the ASD trip when accelerating, running, decelerating, or when not running?  
• Does the ASD reach the commanded frequency?  
• Does the ASD trip without the motor attached?  
• Does ASD trip with an unloaded motor?

User Notification Codes  
The User Notification codes appear on the Frequency Command screen while the associated function is  
active.  
User Notification codes notify the user of active functions that are usually only momentary under normal  
conditions and are active for the duration of activation only. User notification events are not error  
conditions and only convey active system functions to the user.

Trips/Faults  
A Trip is an ASD response to a Fault (though, Fault and Trip are sometimes used interchangeably). A  
Trip is a safety feature that disables the ASD system in the event that a subsystem of the ASD is  
malfunctioning.  
Listed in Table 13 are the possible Faults that may cause a Trip and the possible causes. When a Trip is  
incurred the system displays the Fault screen. The Fault screen identifies the active Fault.  
Table 13

• Acceleration time is too short.  
• DC Injection current is too high.  
• V/f setting needs to be adjusted.  
• Motor running during restart.  
• ASD or the motor is improperly matched to the application.  
Autotuning Err  
Autotune readings that are significantly inconsistent with the configuration  
information.  
• A non-3-phase motor is being used.  
• Incorrect settings at parameter 0400, 0413, or 0414.  
• Using a motor that has a significantly smaller rating than the ASD.  
• ASD output cabling is too small, too long, or is being housed in a cable tray with  
other cables that are producing an interfering EMF.  
• Motor is running during the Autotune function.  
Note:  
The event that caused the Trip(s) must be corrected or must decrease to less than the threshold  
value required to cause the trip to allow for a Reset to be recognized. In the event of multiple  
active trips, the trip displayed will remain until all faults are corrected and all trips are cleared.

Viewing Trip Information  
In the event that the condition causing an Alarm does not return to the normal operating level within a  
specified time a Trip is incurred.  
When a trip occurs, the resultant error information may be viewed either from the Trip History screen  
(Program  
System Information and Setup  
Trip History) or from the Monitor screen.  
Trip History  
The Trip History screen records the system parameters for up to 24 trips (RTC option required). The  
recorded trips are numbered from zero to 23. Once the Trip History record reaches trip number 23, the  
oldest recorded trip will be deleted with each new record stored (first-in first-out). The Trip # field may be  
selected and scrolled through to view the recorded trip information for a given trip number. The monitored  
parameters are listed in Table 14 as At-trip Recorded Parameters (parameter readings at the time that  
the trip occurred).

Trip Record at Monitor Screen  
The Monitor screen records and displays the trip name of up to four trips and catalogs each trip as Past  
Trip #1, Past Trip #2, Past Trip #3, and Past Trip #4. Once reset (Clear Trip), the trip records are  
erased. If no trips have occurred since the last reset, No Error is displayed for each trip record.  
Note: An improper ASD setup may cause some trips — reset the ASD to the factory default  
settings before pursuing a systemic malfunction (Program  
Utilities  
Type Resets  
Restore Factory Defaults).  
The at-trip frequency of the last incurred trip may be viewed at the Monitor screen (see pg. 45). The  
Monitor screen at-trip record is erased when the ASD is reset and may be viewed without the use of the  
RTC option. The current output frequency is displayed here when no trip is active.  
Clearing a Trip  
Once the cause of the trip has been corrected, performing a Reset re-enables the ASD for normal  
operation (clears the fault screen).  
The fault screen may also be cleared using either of the following methods:  
• Cycling power (trip info may be saved via parameter 0602 if desired),  
• Pressing the Stop|Reset key twice,  
• Remotely via the communications channel,  
• Momentarily connecting terminal RES to CC of the Control Terminal Strip, or  
• Via Program  
Utilities  
Type Resets  
Clear Psast Trips.
