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.

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
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.
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.
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
The output terminals of the ASD (T1/U, T2/V, and T3/W) must be connected to the motor that is to be
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.
W7 ASD Installation and Operation Manual
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.

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
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
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.

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.

W7 ASD Installation and Operation Manual
The Changed From Default feature allows the user to view (or change) the parameters that are
different from the default or the post-reset settings. Once the Changed From Default screen is
displayed, the system scrolls through all of the system parameters and halts once reaching a changed
parameter.
The Rotary Encoder may be clicked once clockwise to continue scrolling forward or clicked once
counterclockwise to begin scrolling in reverse. With each click of the Rotary Encoder from a stop, the
system scrolls through the parameters and stops at the next parameter that has been changed.
Pressing the Rotary Encoder while a changed parameter is displayed accesses the settings of the
changed parameter for viewing or changing.
Pressing ESC while the system is performing a Changed From Default search terminates the search.
Pressing ESC when done searching (or halted at a changed parameter) returns the system to the
Program menu.
Parameter settings may also be changed via Communications. See the 7-Series Serial
Communications Manual (P/N 53840) for further information on using communications to change
parameter settings. The 7-Series Serial Communications Manual may be acquired from the

Monitor Screen
The Monitor screen reports the status of motor performance variables, control settings, and
configuration data during motor operation. There are 30 items that may be monitored from this mode.
The items are listed and described below.
Up to four of the underlined monitored items listed below may be displayed at the Frequency
Command screen while the ASD is running. See Program
System Information and Setup
Monitor Selection to select the monitored items to be displayed.
Note: The Monitor screen lists the read-only status of the listed parameters.
Trip Hold Frequency — If tripped, this field records the at-trip frequency. Otherwise, the current
output frequency is displayed.
Past Trip #4 — This feature reads and stores trip records and is the first of four recorded trips.
Past Trip #3 — This feature reads and stores trip records.
Past Trip #2 — This feature reads and stores trip records.
Past Trip #1 — This feature reads and stores trip records and is the last of four recorded trips.

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

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.

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)
Capacity, Dynamic Braking Resistance, and DC Injection Braking Current.

Changeable During Run — Yes
Minimum — 0.0
This parameter sets a frequency that, during acceleration, deceleration, or while
running, will not be output from the ASD. This parameter operates in
conjunction with the bandwidth setting of Jump Frequency #1 Bandwidth.
During acceleration, the output frequency of the ASD will hold at the frequency
of the lower level of the Jump Frequency (1, 2, or 3) range until the
programmed acceleration ramp reaches the upper level of the Jump Frequency
range. Then, the output frequency of the ASD will accelerate to the upper level
of the Jump Frequency range and continue upward as programmed.
Maximum — Max. Freq.
Units — Hz
During deceleration, the output frequency of the ASD will hold at the frequency
of the upper level of the Jump Frequency range until the programmed
deceleration ramp reaches the lower level of the Jump Frequency range. Then,
the output frequency of the ASD will decelerate to the lower level of the Jump
Frequency range and continue downward as programmed.
If overlapping Jump Frequency bandwidths are set up, the system will respond
with one bandwidth setting that includes the total range.
Once set up and enabled, it is on in all control modes.
User-selected frequencies may be jumped to avoid the negative effects of
mechanical resonance.

Parameter Type — Numerical
Factory Default — (ASD-dependent)
Changeable During Run — No
Minimum — 0.50
In the event of a momentary power outage, the output signal of the ASD will
cease. Upon restoration of power, the ASD will output a low-level signal that
will be used to determine the rotation speed of the rotor.
The low-level signal will start scanning the motor at FH and decrease until it
reaches 0.0 Hz or it matches the signal produced by the turning rotor. Once the
rate of rotation is determined, the ASD will provide the normal output to
engage the motor from its present speed.

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.

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
Ref Priority Sel.

Table 6. (Cont.) Discrete Input Terminal Assignment Selections and Descriptions.
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.
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.
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?

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:
• 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
