Chapter 3 - Connecting and Installing Your Impulse
A. Connecting a Motor to the Impulse
Connecting an IDC Motor
The A+, A-, B+, and B- phase outputs power the motor windings.
Connect motor wires to the motor connector (supplied) and plug the wired connector into the drive.
Drawings below provide color codes for IDC motors.
GND is internally connected to the earth pin on the power connector. This provides a convenient
terminal for grounding the motor frame and a motor cable shield. Note: If the motor is mounted on
a machine that is grounded, do not connect the motor to GND.
The two INTLK pins must be jumpered together on the motor connector to allow power to the
motor.
CAUTION! Do not remove the motor connector from the Impulse drive while power is
applied. Removing the connector while power is applied could damage the connector pins.
Do not extend the interlock jumper wire to provide protection for another connector interface. The
interlock circuit is susceptible to trips caused by noise-pickup in cables (20 kHz switching).
Note: This is a high-impedance safety-interlock circuit. If the interlock wire breaks, or the connector
is removed, the current to the motor is immediately stopped, the drive faults (latches) and the LED
on the front panel of the Impulse will flash five times (see LED Diagnostics on p. 3-8).

Connecting a Non-IDC Motor
One of the Impulse drive’s more advanced features, Open Loop Stall DetectTM, is guaranteed only
when matched with one of IDC’s S or P-series motors.
IDC’s S and P series motors have custom windings to provide optimum dynamic performance with
the Impulse. If you use another manufacturer’s motor, refer to Non-IDC Motors in Chapter 6,
Hardware Reference, for more information.

Chapter 3 - Connecting and Installing Your Impulse
B. Serial Communication Connections
Making RS-232/RS-485 Connections
The standard Impulse drive uses a 3-wire implementation of RS-232C. The RX, TX, and COM lines
are the serial signals supported. No hardware handshaking is required. Note that some RS-232C
devices require handshaking, such as RTS and CTS. It is the responsibility of the user to disable this
handshaking via software or hardware (see Troubleshooting RS-232C Communication Problems on
page 3-6 for more information).
If you will be using RS-485 communication, the typical 5-wire interface connection to a “host” is
shown below. See “Multi-Dropping Impulse Drives with RS-485” on the next page for information
on using termination resistors. Note: the maximum cable length for RS-485 communication is 4,000
feet.
Make your RS-232C connection as shown below. The PC Cable (IDC P/N SS-RS232) shown below,
is an ideal choice for making trouble-free RS-232C connections to the Impulse.

Daisy-Chaining Impulse Drives
Your Impulse also supports daisy chaining. The unit address (range 1-99) can be set via the keypad
or in Application Developer.
Rules for Daisy Chain Operation
1. Units on a daisy chain must be “device addressed’ (numbered) in order for communications to
work properly. A unit’s address should increment upward as you move down the daisy chain
from the PC (see illustration below).
2. Do not duplicate unit addresses.
3. Any loose RS-232C connections or miswiring along the daisy chain will cause communications
to fail. Please double check wiring if communication problems arise.
4. Please call IDC if you need to daisy chain more than 99 drives.
5. The hardware diagram below shows how to connect the daisy chain.

Chapter 3 - Connecting and Installing Your Impulse
Troubleshooting RS-232C Communication Problems
If communications between computer and Impulse are unsuccessful, one or more of the following
procedures will usually solve the problem:
1. Host transmit (TX) must be connected to receive (RX) of the drive unit, and receive (RX) of the
host must be connected to transmit (TX) of the drive. If communication fails, try switching
connections on either the host or the drive.
2. Some serial ports may require handshaking.
Jumpers
RTS to CTS
DSR to DTR
9 pin D
7 to 8
4 to 6
25 pin D
4 to 5
6 to 20
Jumper RTS to CTS, and DSR to DTR (see table).
3. Check your ground connections. The COM
terminal should be isolated from earth ground. Use
DC common or signal ground as your reference - do not use earth ground or shield.
4. Voltage between TX and COM should be -8.0 to -12.0 VDC. Voltage between RX and COM
should be 0 to -0.5 VDC. Consult factory if measured voltages are outside these ranges.
5. For RS-232C only: If any cable is more than 50 ft. long, you should use a line driver, optical
coupler, or shield. Shields must be connected to earth ground at one end only.
6. Reminder for PDA Users: Programs such as Palm’s Hotsync Manager take over a comm. port.
Be sure to close/exit these types of programs if you are using serial communication with your
Impulse.
7. Important Application Note Regarding PC Com Port: PC FIFO (First In First Out) Buffers
should be used and adjusted to the highest settings for fastest performance. This applies to both
Receive and Transmit Buffers.
•
In your Windows operating system, go to Start > Settings > Control Panel > System >
Device Manager > Ports (Com 1, Com 2) > Port Settings > Advanced > Buffer.
•
Select Use FIFO Buffers, and ensure both Buffers (Receive and Transmit) are adjusted to
the High setting for best performance.

Chapter 3 - Connecting and Installing Your Impulse
D. Connecting AC Power
There is no ON/OFF switch on the Impulse. AC power is
applied by plugging the *power cord (included) into the
connector on top of the Impulse.
Input voltage must be in the range of 120 VAC ± 10%, single
phase, 50/60 Hz, 500 VA max @ 4 Amps. Operation outside
these specifications will result in reduced performance, drive
faults, and may damage the drive.
When power is applied, the LED on front of the drive should
briefly turn red, then steady green. If a red light is present, see
Section E of this chapter for more information on fault detection
codes.

Power
Supply
*Note: If the AC power cord requires replacement, the
replacement must be rated for Hard Usage or Extra Hard
Usage.
E. LED Diagnostic Indications
The Impulse drive detects and resolves fault conditions (see table below). Faults are signaled by
either a steady red or a flashing red LED on the front panel. A solid green LED indicates normal
operation. A slowly flashing green LED indicates a shutdown (disabled), while a rapidly flashing
green LED signals a regen dump. Faults are cleared by either 1) cycling power, 2) sending a RESET
command via the serial port or configurable logic input, or 3) probing the motor if the LED is steady
red.
For more detailed explanation of faults refer to Chapter 7, Troubleshooting the Impulse.

F. Connecting Inputs and Outputs
Connect your inputs and outputs to IDC’s 961/962 Indexer according to the information below.
Schematics for Impulse I/O circuits can be found in Chapter 6, Hardware Reference
Application Notes
1. On 961/2, ensure that Step/Direction and Differential Jumpers are installed (see 961/2 manual).
2. If using IDC P/N SS-I/O or SS-I/O-6 cable, cut one end of the cable if necessary (see table
below for SS-I/O cable color-code). If making your own cable, or using a non-IDC indexer,
refer to the Impulse I/O Schematics (Chap. 6) and the 25-pin Connector drawing below.
3. Use a shielded cable, and connect the shield only at the Impulse. Connect shield to pin 9.
4. IDC offers a 25-pin screw-terminal breakout board (shown below) to add convenience and
flexibility to your application. Terminals on the breakout board match the pins of the 25-pin
connector on the Impulse.
5. When wiring TTL signals to other manufacturer’s indexers, the Step TTL command signals
from the controller should be wired to Step +, the Direction signal to Dir +, and the Shutdown
signal to SD + (Step -, Dir -, and SD - should not be connected). Remember, the drive common
must be connected to the controller common.
6. Activating the Shutdown input disables the drive amplifier and de-energizes the motor. When
this input is OFF the drive is enabled and the motor is energized. The polarity of this input is
configurable.
7. The open-collector Fault Output turns ON (Active High) when any one of the LED-indicated
conditions occur (see Section E, LED Diagnostic Indicators). The output stays ON while the
LED flashes.

X-Smoothness (Xtreme Smoothing™)
The X-Smoothness tab is the most advanced low-speed tuning feature currently available on any
microstepping drive. The benefits of low-speed smoothness are 1) reduced vibration, and 2) an
increase in torque, which was typically lost to vibration before the arrival of the Impulse drive.
Achieving this revolutionary smoothness is easily and quickly accomplished by following the
simple procedure below. Note: the motor must be disconnected from its load while performing
Xtreme Smoothing™.
•
X-Smoothness Sliders - Click and drag the indicator to change a value.
•
Test Speed - This text input box displays the Recommended Test Speed and may be edited
if necessary.
•
Recommended Test Speed - This value has been either 1) pre-configured for IDC motors,
or 2) calculated when a custom motor file was created in the Advanced Motor Editor. Verify
that this value has been entered in the Test Speed display.
•
Run Test/Stop Test Button - Toggles between Run Test and Stop Test.
Restore - Restores each X-Smoothness to the previous values.
•
Adjusting X-Smoothness #1, #2, #3
Important: Whether using an IDC motor or a non-IDC (custom) motor, all six X-Smoothness
values (L1, L2, M1, M2, H1, H2) must be adjusted in the order described in the following
procedure. Note: Slider bars L1 and L2 are interactive, as are M1 and M2, and these interactive
sliders should be alternately adjusted until the deepest null setting is achieved.
X-Smoothness #1
Recommended values for L1 and L2 have been pre-configured for IDC motors, but we
recommend that these settings be verified and adjusted if necessary by the following procedure.
If you are using a custom motor file, these values were calculated in the Advanced Motor Editor.
1. Press the Run Test button.
2. Move slider L1 left and right until the smoothest running condition is reached.
3. Move slider L2 left and right until the smoothest running condition is reached.
4. Press Stop Test.

Advanced (Advanced Tuning)
The Advanced tab allows you to enable/disable and modify various advanced performance features
of the Impulse drive.
Note: Observe decrease in
Gain when Multi-Stepping is
Enabled.
Anti-Resonance
•
Enable this feature by selecting the Enabled check box. Ensure that both Damping Gains
are configured if Anti-Resonance is enabled.
Current Reduction Mode
•
Select Stop to enable the stop mode current reduction time-out period. Stop Mode reduces
current by 25%. This time-out period is directly entered in milliseconds. The valid range is
6 to 19,656 ms.
•
•
Select Idle to set the idle mode current reduction time-out period. This time-out period is
directly entered in seconds. The valid range is 0 to 3600 seconds (0 = disabled).
In the % box, enter the percentage that current will be reduced after the idle mode time-
out has expired. The valid range is 0 to 100%.
Profiling
•
Select Dynamic Smoothing Enabled by clicking on the check box and entering the recom-
mended gain in the input box. Dynamic Smoothing™ is an IDC proprietary method of auto-
matically reducing “jerk” (sudden change of acceleration) which is often inherent in move
sequences generated by indexers. Dynamic Smoothing™ is similar in effect to so-called S-
curve profiles. The softening of accel/decel transients sharply reduces ringing in the motor
and various attached structures.
•
Select Multi-Stepping Enabled for more aggressive dynamic smoothing. Gain will be
1/10 of the recommended gain when Dynamic Smoothing is enabled. Multi-Stepping™ is
an IDC proprietary method of obtaining very smooth motion from step motors when using
low resolution indexers, i.e. 200, 400, 1000 steps/rev. The Multi-Stepping™ feature, when
enabled, executes coarse stepping regimens by using microsteps to fill-in between the
widely-spaced, low-resolution steps. This is a form of interpolation that produces smooth
motion in an otherwise coarse and noisy stepping system.

I/O Descriptions
Input Descriptions
EOT (End of Travel): Activation of an End of Travel input during any motion (external steps or
internal move engine) will terminate motion at the rate specified by the Stop Rate parameter, and
latch the direction. Motion is only allowed in the direction opposite of the latched EOT direction
until a negative edge (activation on to activation off) is made. This guards against the switch
activator becoming “trapped” if the Stop Rate was insufficient to stop motion in the activation
region. The EOT input is also required in the execution of Home type moves. See Stored Move

Chapter 4 - Configuring Impulse with Application Developer
Setup - Editing Stored Moves later in this chapter for more information on Home moves.
Jog +: Activation of a Jog+ input will jog the motor at the acceleration rate specified by the Jog
Accel parameter and the velocity specified by the current state of a Jog Speed input in the positive
direction. If a Jog Speed input has not been configured, the motor is jogged at the velocity specified
by the Jog-Low parameter.
Jog -: Activation of a Jog- input will jog the motor at the acceleration rate specified by the Jog Accel
parameter and the velocity specified by the current state of a Jog Speed input in the negative
direction. If a Jog Speed input has not been configured, the motor is jogged at the velocity specified
by the Jog-Low parameter.
Jog Speed: The Jog Speed input toggles between the low and high velocities for the Jog+ and Jog-
inputs as specified by the Jog-Low and Jog-High parameters. If the state of Jog Speed input is
changed while a Jog+ or a Jog- input is asserted, the motor will accel or decel at the Jog Accel rate
to the high or low velocity respectively.
Kill: Activation of a Kill input terminates any motion (external steps or internal move engine)
instantly without a deceleration ramp.
Move Select: The Move Select input is used to trigger one of the 7 possible stored moves (Motion
Node option only). Each configured Move Select input serves as a bit in a 3-bit binary number
therefore allowing the binary representation of numbers 0-7. The Move Select configuration option
is only available on inputs #1-#3 with input #1 being the least significant bit (LSB) and input #3
being the most significant bit (MSB). Note that the bit places are fixed with respect to the input
numbers. For example, if input #1 were configured as an EOT and input #2 were configured as a
Move Select, asserting input #2 would run stored move #2 not stored move #1. Below is a Move
Select assertion table:

To guard against inadvertently selecting moves during input transitions, all Move Select inputs must
be stable for the time specified by the Move Select Input Scan Time. See the “Editing Stored Moves”
section for more information on setting the Move Select Input Scan Time.
Stop: Activation of a Stop input terminates any motion (external steps or internal move engine) at
the rate specified by the Stop Rate parameter.
Warm Boot: Activation of a Warm Boot input resets the drive and clears any latched fault
condition. To guard against a Warm Boot input being inadvertently held asserted, the Warm Boot
input is negative edge triggered (activation on to activation off). To insure the negative edge is
latched, the Warm Boot input must be held asserted for at least 500µs before releasing.

Brake: The Brake output is activated on any fault condition. This provides a control signal to
engage a brake when the Impulse loses torque due to a fault. The Brake output also provides a
polarity-configurable fault output since the dedicated fault output is fixed as an active high, sinking
output. Note: The Brake output is not intended nor designed as a power source for a mechanical
brake.
In Motion: The In Motion output is activated upon receiving incoming step pulses or when a stored
move (Motion Node option) is running. The minimum step frequency that the internal velocity
tachometer can render is 156.25 Hz (156.25 / Step Resolution in RPS). Input step frequencies below
156.25 Hz will not activate the In Motion output.
Stall: The Stall output is activated when OLSD™ (Open Loop Stall Detect) detects a motor stall.

Stored Move Setup - Editing Stored Moves
If your Impulse is equipped with the Motion Node option you will be able to access the Stored
Move Setup menu shown below. The Impulse will store seven (7) moves which can be invoked
through binary inputs, by serial commands (see Appendix B), or via the Run > Stored Move
window. Moves are edited in the Stored Move Setup window via Edit > Stored Move or the Edit
Stored Moves tool bar button.
•
•
Click on the Edit Stored Moves button.
Use the information provided below to configure your Stored Moves in the Stored Move Setup
menu.
Stored Moves are defined by the parameters Accel (acceleration rate), Decel (deceleration rate),
Velocity, Position/Distance, and Move Type. Distance Units pertaining to the four dynamic
parameters are selected in the Project Wizard or the Axis Setup tab (Setup > Axis > Mechanics >
Change Mechanical System/Units). The three move types are Incremental, Absolute, and Home,
each selectable by a radio button.
Incremental moves are indexed to the commanded position from the current position.
Absolute moves are indexed to the commanded distance.
Home moves function as follows:
1. The drive moves at the specified velocity (direction selected by velocity sign) until it sees an
EOT input go active.
2. On the active going transition, the drive decelerates according to the specified Stop Rate
parameter.
3. The drive reverses direction and moves at 1/16 of the specified Velocity until it sees an active-
to-inactive transition on the EOT input. This locates the inside edge of the EOT sensor precisely.
4. The drive stops the slow move and executes an incremental move defined by the Distance entry.
This final move is always in the opposite direction to the initial search direction specified by the
sign of the Velocity parameter. This move constitutes an offset from the edge of the EOT sensor.
5. After the final position is reached, the drive zeros its position counter. All subsequent “absolute”
moves will be relative to this Home position.

Chapter 4 - Configuring Impulse with Application Developer
Note: Homing is predicated on the assumption that the system is positioned somewhere
between the EOT switches when the home move is invoked. If the system is initially outside the
interval between the EOT switches, the homing routine will fail in one of two ways: (1) carriage
will be driven against mechanical end-stop. (2) carriage will end up “homed” outside the
interval between the EOT switches.
Digital inputs are configurable as EOT (Active High/Active Low) on the Setup > I/O menu.
More than one Home move can be specified and stored simultaneously if it serves a purpose.
Input Scan Time - This is the time the drive requires the binary input selection to be stable prior to
triggering a move. Its primary purpose is for debouncing inputs. Scan time can be configured from
0 to 19,656 milliseconds.

Run Menu
•
•
The Run > Stored Move menu is available only on drives equipped with the Motion Node
option and can only be accessed from the menu bar. This menu allows you to view all stored
move profiles and to run and stop each stored move.
No editing of moves is available on this menu. During the execution of any stored move, the
Impulse ignores the step and direction inputs. Any activity on those inputs is completely lost.
In other words, stored moves are not added in with incoming step commands. Typically, it is
not a useful control stratagem to trigger a stored move while engaged in motion commanded
via the step and direction inputs.
•
•
Binary inputs (digital inputs 1, 2, and 3) may be configured as Move Inputs (Active High/
Active Low) for triggering stored moves (Setup > I/O).
Serial Commands - A host system may trigger moves over the serial RS-232/485 connection.
This procedure involves the transmission of Unit Addressing, Parameter Indexes, Data and
Checksum. The advanced topic of serial communications protocol is covered separately in
Appendix B.

Chapter 5 - Configuring Impulse with an IDC Keypad
Section 1 of this chapter is intended primarily to familiarize new IDC keypad users with the FP100
Impulse Keypad, and we recommend this section be reviewed by those experienced with the FP220
keypad as well. If you are using an FP220 keypad (version 3.00 and above) to configure the Impulse,
it is imperative that the keypad DIP-switches be set as shown on the next page.
Section 2 provides step-by-step procedures for configuring the Impulse with either the FP100 or
FP220 keypad.
Section 1 - Introduction to the FP100 Impulse Keypad
The FP100 version of the IDC keypad was developed solely for the Impulse drive, while the FP220
(version 3.00 and higher) can also be used with the Impulse and with IDC’s extensive line of Smart
Drives. The FP100-RS485 and FP220-RS485 keypads may be used with an Impulse and RS-485
communication.
The keypad was designed to provide operators with a convenient way to configure an application,
and though it functions primarily as an operator interface, it is also effective as a troubleshooting
tool.
Application Note: If a project file was created in Application Developer using the Extended level
of Numeric Precision (Axis Setup > Command > Numeric Precision > Extended), you will receive
a precision error message when the file is loaded into a keypad. Only the Standard level of numeric
precision (Axis Setup > Command > Numeric Precision > Standard) is compatible with the precision
level of the keypad. See Chapter 4, Configuring Impulse with Application Developer.

Keypad Hardware Features
Adjusting Contrast
On the back of the keypad there is a plastic potentiometer, adjustable with a flathead screwdriver.
This is used to adjust the contrast on the LCD display. If the Impulse drive and keypad were
purchased together, this adjustment has been made by IDC. Some adjustment may still be necessary
to accommodate a variety of lighting conditions or viewing angles.
Remote-Mounting the Keypad
The keypad can easily be mounted and sealed to NEMA 4 specifications by using the included
mounting gasket and 6-foot communication cable. See Chapter 6, Hardware Reference, for
important information on mounting the keypad and extending cable length.
DIP Switch Settings
DIP-switch settings on the back of the FP100 keypad have no effect on either the keypad or the
Impulse drive.
NOTE: If you are using an FP220 keypad with your Impulse, you must set DIP-switch #3 to the ON
position and switch #s 1, 2, and 4 to OFF. Setting switch #3 to ON does not apply when using the
FP220 with other IDC drives or controls. See appropriate user’s manual or call IDC Applications
Engineering for information on keypad applicability.

Chapter 5 - Configuring Impulse with an IDC Keypad
Section 2 - Configuring Impulse with an IDC Keypad
This chapter contains information and steps for developing an Impulse project file with the FP100
keypad. Configuring all parameters in the EDIT menu will ensure that your project file is setup
correctly.
The task of configuring your Impulse for a specific application consists of customizing a number of
software parameters to match the mechanics of the system. These parameters include motor setup,
I/O, jog, stored move profiles, and advanced tuning.
Application Note: If a project file was created in Application Developer using the Extended level
of Numeric Precision (Axis Setup > Command > Numeric Precision > Extended), you will receive
a precision error message when the file is loaded into a keypad. Only the Standard level of numeric
precision (Axis Setup > Command > Numeric Precision > Standard) is compatible with the precision
level of the keypad. See Chapter 4, Configuring Impulse with Application Developer.
The configuration procedures in this section will follow the format of the example below:

Configuring Motor Type
This menu allows you to select a preconfigured IDC motor type. In addition to IDC motor types, the

1. Using ↑↓ arrow keys, scroll the list of motors until the desired motor appears on the bottom line.
2. Press ESC to save your motor selection.
Probing the Motor
A new drive setup must be instructed to probe itself after you have selected motor type on the keypad
(procedure on next page). The internal setup parameters obtained during the motor probe are stored
in nonvolatile memory so that the process need not be repeated every time the power is cycled.
Each time a different type of motor is connected to the drive, the motor must be probed. The drive
should always be reconfigured for a new motor to avoid degrading the anti resonance feature and
OLSD™. When the drive is probing the attached motor, a short 1 kHz tone will be heard emanating
from the motor. Depending on motor type, this tone may persist for anywhere from several seconds
to half a minute.
The motor probe may be initiated (1) immediately after configuring motor type, or (2) after all
parameters in the EDIT menus have been configured. In either case, the following procedure applies:

keys, and the move profile parameters are selected by using the left or right arrow keys. Units of
acceleration, deceleration, velocity, and distance are defined in EDIT > SETUP > MECH > UNITS,
and scaled by EDIT > SETUP > MECH > RATIO.
There are three (3) types of stored-move profiles:
INC - Incremental
ABS - Absolute
HOME - Home Routine
Incremental moves are indexed the commanded distance from the current position.
Absolute moves are indexed to the commanded position.
Home moves provide a built-in routine to automatically find an exact position to reference all moves
from (i.e. to find the zero position after a system power cycle.) Home moves require the use of at
least one EOT limit switch and one input configured as an EOT. Home moves do not require the use
of a home switch.
Home moves are executed as follows:
1. The drive begins moving in the direction specified by the sign of the velocity. Note: Negative
velocities are only valid with Home moves. The move distance is always forced to be the sign
opposite of the velocity sign.
2. The drive moves at the commanded velocity until an EOT switch is encountered and decels at
the rate defined in EDIT > SETUP > COMAND > STPRTE.
3. The drive then switches direction and moves at 1/16 the commanded velocity to find the leading
edge of the EOT switch.
4. The drive then performs a final incremental move from the edge of the EOT switch equal to the
defined move distance.

1.When wiring TTL signals to other manufacturer’s indexers, the Step TTL command signals from
the controller should be wired to Step +, the Direction signal to Dir +, and the Shutdown signal
to SD + (Step -, Dir -, and SD - should not be connected). Remember to connect commons.
2.Activating the Shutdown input (logic low) disables the drive amplifier and de-energizes the motor.
When this input is off (logic high) the drive is enabled and the motor is energized.

The PSR-2 position sensor is a nor-
mally closed Reed Switch and must be
connected to two (2) separate inputs, as
shown here. This leaves two (2) inputs
for move selects, which allows for the
selection of three (3) stored moves.

Chapter 7 - Troubleshooting the Impulse
This chapter covers common faults, their possible causes and remedies. Also include in this chapter
are Impulse Limits Tables for a variety of operational parameters, e.g. the Acceleration/
Deceleration/Velocity Limits Table.
The Impulse drive detects and resolves fault conditions. Faults are signaled by either a steady red or
flashing red LED on the front panel. A solid green LED indicates normal operation. Most faults are
cleared by either 1) cycling power, 2) sending a RESET command via the serial port or configurable
logic input, or 3) probing the motor if the LED is steady red.
Read the CAUTION below before troubleshooting your Impulse.
CAUTION!
•
•
•
Always use caution when working with mechanical systems. Gears and screw-driven
cylinders are capable of exerting tremendous force against an obstruction.
Always ensure that power to your system is OFF before performing any mainte-
nance activity, or making any connections or adjustments.
Do not insert objects into the Impulse drive. High voltages could cause personal
injury, and equipment could be damaged beyond repair.
•
Do not open the Impulse drive. The factory warranty will be voided if the drive is
opened.
Troubleshooting Table
This table provides possible remedies to other problems you might have with your application.

Symptom
Possible Causes
Possible Remedies
The keypad is blank, but the
backlight is on.
You have an older keypad that re-
quires new firmware. The Impulse
requires a keypad with Version 3.00
firmware or higher.
Call IDC for a free firmware upgrade
to your keypad.
The keypad is blank and the
backlight is off.
The keypad is not receiving a good
+5VDC signal.
Check wiring, verify that the +5VDC
is between 4.8 and 5.2V.
It is difficult to read the display The contrast potentiometer needs
adjustment
Adjust the contrast with the pot on
the back of the keypad.
Can’t Communicate over
RS232, but keypad works.
If the keypad works, the Impulse
RS232 port is working. Something
else is configured wrong (i.e. wiring,
configuration, address).
Refer to Chapter 5, RS232 Trouble-
shooting, for help on this subject.
Can’t Communicate over
RS232, and keypad does
NOT work.
Impulse is configured as RS485.
Check the label to make sure you
don’t have an RS485 version. Either
connect to RS485 or call IDC (or your
distributor) to exchange units.
The keypad is disabled.
The serial port is not working.
Motor not probed.
Enable keypad through DIP switch
on back of keypad and try again.
Call IDC (or your distributor) for ap-
plication assistance.
Steady Red LED
If using Application Developer, use
the Project Wizard or select Run >
Probe Motor from the main menu. If
using a keypad, select RUN >

manded acceleration or velocity.
Check your AC line voltage to verify
it is within the Impulse’s limits.
4 LED flashes
(Over Current Fault)
The motor is mis-wired or internally
shorted. The Impulse is protected
against such shorts, but you will
need to correct the problem to pre-
vent the fault.
With power off recheck connections.
Check Impulse current setting to
make sure you did not accidentally
damage a winding by using a higher
current than the motor is rated for.
Check to see the motor phases are
not shorted to one another or to the
case of the motor. The resistance in
each phase should be about the
same; only a few ohms. If the phas-
es are open or have large resistanc-
es, the motor is probably damaged
and should be replaced.
5 LED flashes
(Interlock Fault)
Motor connector does not contain
an interlock jumper, motor has been
disconnected, or interlock jumper is
loose.
Ensure interlock jumper is securely
wired into motor connector. Ensure
motor connector is securely plugged
into the motor jack on the drive.

6 LED flashes
(Over Temperature Fault)
Internal Fan or Heatsink Tunnel is
clogged or restricted (internal temp.
has exceeded 68° C (154° F).
Remove obstruction (clean by blow-
ing shop air through the tunnel.
Ambient air in cabinet is too hot.
The Impulse can produce 20 Watts
of heat. If multiple units are installed
next to each other, the cabinet must
be adequately ventilated to remove
heat.
The cooling fan is not turning.
Cooling fan is inoperable. Return unit
to factory for repair.
7 LED Flashes
(EEPROM Checksum Fault)
At power-up the drive tests the in-
tegrity of its non-volatile memory by
computing a checksum. This fault
indicates an abnormal or defective
condition in the drive.
The fault can be cleared by issuing a
default configuration from Applica-
tion Developer and then reconfigur-
ing the drive for the target motor. If
the fault recurs, the drive is definitely
defective. The user should not be
able to cause this fault inadvertently
through any combination of com-
mands or actions.
An error occured during download
or EEPROM write.

Appendix A - Recommended Wiring Practices
Appendix A: Recommended Wiring Practices for IDC Controls
When configuring your Impulse please follow the wiring practices listed below:
•
•
Earth ground your machine at one point using a star configuration (shown at right).
Multiple earth grounds can cause a ground loop (see Preventing Ground Loop below).
Avoid long cable runs. The longer the cables, the lower the signal-to-noise ratio in your
application.
•
•
Use shielded motor and encoder cables along the entire cable run.
Separate the signal wires (I/O, encoder, etc.) from the motor wires, AC power wires, and other
sources of noise in your application.
•
Avoid extending cables in the field via junction boxes, terminal strips, or Molex connectors.
These types of connectors are typically unshielded (as is wire going into and out of the connec-
tor) and are places where noise may be injected into the system.
•
•
Connect cable shields at the control end of your machine. Connect the motor cable shield to
GND, and connect the encoder shield to COM on the control.
Do not connect the logic common (COM) of the IDC control to earth ground on your machine
or to the GND terminal on the control/drive. Separating earth ground from logic common min-
imizes the potential for ground loops.
•
•
•
Use shielded cables inside your panel (if control is panel or cabinet-mounted) for I/O and
encoder wiring.
Use differential, line-driven encoders with shielded, twisted-pair encoder cables. Single-ended
TTL encoders are susceptible to noise and should be avoided.
For optimum noise immunity use IDC motors and encoders with IDC controls.
Preventing a Ground Loop
Insert an ungrounded adapter to
break the ground loop.
Do Not
Connect
Pig-tail
Wire
Possible Ground Loop
Additional Wiring Practices When Connecting an IDC Control to a PLC
•
•
Connect the PLC logic common and the IDC COM terminals together.
Disconnect the jumper between Pull-Up (or P-Up) and +12 VDC on the IDC control. Connect
the positive terminal of the PLC power supply to Pull-Up (or P-Up), and connect the Power
Supply common to the COM terminal on the IDC control, or to the PLC logic common (these
should both be at the same potential).
•
•
IDC inputs are Sourcing, so PLC outputs connected to IDC inputs should be Sinking.
IDC outputs are Sinking, so PLC inputs connected to IDC ouputs should be Sourcing.

Appendix B - Impulse Advanced Programming
Appendix B - Impulse Advanced Programming
The purpose of this section is to provide the information necessary for the user to communicate with
an Impulse drive over a serial connection without using IDC Application Developer. Since the
Impulse communications protocol is not ASCII character based, the terminal window in IDC
Application Developer and terminal emulation programs such as Windows™ HyperTerminal are not
compatible for use with the Impulse drive. Therefore, the topics covered here are considered
advanced and require the user to understand how to directly interface with a PLC or PC serial port
through programming (i.e. C or C++) or a MMI / soft PLC software package.
Communications Protocol
Transmission Frame
The Impulse drive does not use the ASCII character set for encoding and parsing serial data but
rather transmits actual numeric data in the form of bytes. This convention allows for faster and more
efficient serial communications by reducing the number of bytes required for data transmission and
eliminating the need to convert ASCII character strings into raw data. Therefore, data references
from this point forward represent actual numbers not ASCII text. For example, a ‘1’ means a value
of 1 not the ASCII text character ‘1’.
The core of the Impulse communication protocol consists of a series of bytes called the transmission
frame. The structure of the transmission frame is as follows:
BYTE #1
BYTE#2
BYTE#3…#n
BYTE #n+1
BYTE #n+2
Unit
Address
Parameter
Index
Data
Bytes
Checksum
Lower Byte
Checksum
Upper Byte
Unit Address
This byte specifies the address of the unit for which this transmission frame is intended. The valid
range for the unit address is 1 to 255 and the factory default address is 1.
Parameter Index
This byte specifies the index of the parameter to be written to or read from. Parameter reads and
writes are determined by the state of the most significant bit of the parameter index byte. If the bit
is zero, the transmission frame is designated as a write. If the bit is one, the transmission frame is
designated as a read. The valid range for the parameter index is 1 to 127 for writes and 129 to 255
for reads. For example, if BYTE #2 in the transmission frame equals 5, this would define a write to
parameter index #5 however, if BYTE #2 equals 133, this would define a read from parameter index
#5. A parameter index can be converted to a read by simply taking the index and adding 128, thus
setting the most significant bit to 1.
Data Bytes
These bytes specify the data to be written to or read from the parameter index. All parameter index
data is in word format (2 bytes) with the least significant byte preceding the most significant byte.
Therefore, the smallest number of data bytes is 2.
Checksum Bytes
These bytes contain the unsigned sum of the Unit Address, Parameter Index and Data Bytes. These
bytes are using for transmission integrity verification.

Appendix B - Impulse Advanced Programming
Byte Receive Time Out
Since there is no end of transmission frame deliminator, the Impulse assumes if no bytes are received
for 60 ms, the transmission is complete. The receive time out is reset on every byte received
therefore, the host system must insure that the latency between transmitted bytes is less than 60 ms.
Receive Buffer Overrun
The Impulse receive buffer is 25 bytes however, there are no valid transmission frames of this length.
Reading and Writing Parameter Data
The Impulse does not support continuous data streaming due to its condensed receive buffer.
Therefore, the host system must wait for a drive response before sending additional read or write
transmission frames.
Read Queries
The following example illustrates a read request of parameter index #113 (Commanded Position)
from unit #2. Bytes are shown in hexadecimal format.
02 F1 F3 00
Checksum Upper Byte
Checksum Lower Byte (Address + Index)
Read Parameter Index (113 + 128)
Unit Address #2
After sending the read request, the host system would need to wait for the drive to respond before
sending another read query or write request. The drive responds to a read with unit address,
parameter index, data and checksum. Assuming the commanded position is 25000 steps, the
response would be as follows:
02 71 A8 61 00 00 7C 01
Checksum Upper Byte
Checksum Lower Byte (Address + Index)
Cmd Position Upper Byte, Upper Word
Cmd Position Lower Byte, Upper Word
Cmd Position Upper Byte, Lower Word
Cmd Position Lower Byte, Lower Word
Parameter Index 113
Unit Address #2
Since Commanded Position is a 32-bit value, the data field in the transmission frame is 4 bytes (2
words).

Write Requests
The following example illustrates a write request of zero to parameter index #113 (Commanded
Position) to unit #1. Bytes are shown in hexadecimal format.
01 71 00 00 00 00 72 00
Checksum Upper Byte
Checksum Lower Byte (Address + Index + Data)
Cmd Position Upper Byte, Upper Word
Cmd Position Lower Byte, Upper Word
Cmd Position Upper Byte, Lower Word
Cmd Position Lower Byte, Lower Word
Parameter Index 113
Unit Address #1
After sending the write request, the host system would need to wait for the drive to respond before
sending another read query or write request. The drive responds to a write with a standard frame of
unit address, a parameter index of zero, data and checksum. A successful write response is as
follows:
01 00 00 00 01 00
Checksum Upper Byte
Checksum Lower Byte (Address + Index + Data)
Transmission Status Upper Byte
Transmission Status Lower Byte
Parameter Index 113
Unit Address #1
A non-zero transmission status indicates an error has occurred. Interpreting the transmission status
is covered in the next topic.
Interpreting the Transmission Status Response
Whenever an error occurs during a transmission received by the drive, the drive reports the error in
the Transmission Status Response. Error response are defined as follows:
0
4
8
No Error

Appendix C - Using Non-IDC Motors with the Impulse
Appendix C - Using Non-IDC Motors with the Impulse
The Impulse drive is an advanced microstepper that employs special digital control techniques to
effect Open Loop Stall Detect™, Multi-Stepping™, Dynamic Smoothing™, Extreme Smoothing™,
and anti resonance control. Although these features can be applied to virtually any step motor, there
are a number of parameters which must be determined for a given motor design in order to get these
processes to work properly. These parameters include such elements as optimum current vector
amplitude, saturation current, rotor inertia, and various electrical model parameters which are
determined by proprietary means.
IDC-supplied motors have been analyzed and modeled for use with the Impulse drive. If you select
a non-IDC motor, there will likely be some degree of difficulty with Open Loop Stall Detect™, and
anti-resonance control. The optimum parameters cannot generally be determined in the field.
Contact your distributor for factory assistance in characterizing non-IDC motors. The remaining
option for those using non-IDC motors is to use the Impulse as a standard drive by disabling the stall
detection and anti resonance features.
ID’s S-Series motors have custom windings to provide optimum dynamic performance with the
Impulse. If you use another manufacturer’s motor, it should meet the following guidelines:
1. 2 phase, hybrid, permanent magnet step motor.
2. 4, 6, or 8 lead motor.
3. Series or parallel inductance rating between 2 - 80 mH. Higher inductance motors will not
damage the drive, but they will have limited dynamic performance.
4. A minimum high-pot test rating of 500 VDC.
If possible, use the manufacturer’s 160 VDC, bipolar current rating. With 4-lead motors, the
manufacturer’s (bipolar) current rating translates directly to the Impulse current setting.
Bifilar wound, 8-lead motors afford the opportunity to connect phase windings in series or parallel.
The parallel connection uses twice the current required by the series connection. There is no industry
standard color code for stepper phase leads (consult motor manufacturer). There are several pitfalls
that users should be aware of: (1) Do not configure the drive to supply the parallel current level into
a series-wired motor (this will damage motor windings). (2) The small dots in the motor wiring
diagrams indicate phasing. Windings must be connected in series-aiding or parallel-aiding
configurations as shown below. If a phase is connected in opposition, the circuit will have no net
inductance and will cause an overcurrent fault in the drive. The same relationship applies to
resistance. (3) Mixing connections (e.g. A to B) will cause an overcurrent fault in the drive.
6-lead motors may be used with the Impulse drive by leaving center-taps unconnected and using the
two outside conductors of each phase. Do not connect the center-tap of a 6-lead motor to the Impulse.
This will result in an overcurrent fault.

Custom or User-Defined Motors
This section applies to users of non-IDC motors or those who would like to modify an existing motor
file.
Note: All motor characteristics must be entered in the text input boxes before the Advanced tuning
feature will be available.
•
Click on the Add Custom Motor button and the Motor Editor will appear.
•
•
Enter a file name for your custom motor in the Motor File Name text-entry box. File
names may be up to eight (8) characters in length (all keyboard characters are valid). This
also applies if you are editing an existing IDC motor file.
Enter the Mechanical characteristics of your custom motor.
Rotor Inertia in kg-m2
Tooth Count in number of teeth on the rotor
•
Enter the Electrical characteristics of your custom motor.
Operating Current is the current-magnitude command to the drive in Amps (it is not
RMS). The value entered represents the peak amplitude of the phase currents.
Saturation Current (in Amps) is critical for the implementation of the Impulse’s exclusive
Open Loop Stall DetectTM feature. Saturation Current has been pre-configured under labo-
ratory conditions for IDC motors, but cannot be accurately determined in the field for cus-
tom motors. If an incorrect Saturation Current is entered, the Open Loop Stall Detect
(OLSD) feature may be ineffective. Contact your distributor or IDC Applications Engi-
neering for assistance.
In the absence of an accurate Saturation Current, you have three options: 1) enter an esti-
mated value based on the characteristics of a similar type of motor, 2) enter the same value
as the Operating Current, or 3) disable the OLSD feature (see Application Developer Setup
> Axis > Advanced tab to disable Stall Detection).
Rated Torque is the rated torque (N-m) of the manufacturer’s motor at the rated current.
This may be set to zero (0) if unknown and it will have no effect on the drive. This number
is used by the Speed Torque Curve utility and is numerically equal to the quotient of the
manufacturer’s specified 2-phase resting torque divided by the specified current (Nm/
Amp). Always convert torque to Newton-meters.
Rated Current is the amplitude of the current generated when the windings are shorted and
the motor’s rotor is back-driven (forced to move). This short-circuit current is of constant
amplitude for speeds above 2 RPS. Determining Rated Current in the field is very diffi-
