NOTE
Single phase can be obtained from a 3 phase "wye" by wiring two of the "hots" (L1 and
L2 or L2 and L3 or L1 and L3) to the single phase control. Power supplied to the drive
must be from a balanced power supply with an earth ground. A floating ground or an
unbalanced supply can permanently damage the drive.
1.3Safety
Read Chapter 2 Safety Information before mounting or wiring the drive.
The STOP and START controls or electrical inputs of the drive must not be relied upon
to ensure the safety of the personnel. They do not isolate dangerous voltages from the
output of the drive or from any external unit. The supply must be disconnected by an
approved electrical isolation device before gaining access to electrical connections. The
drive contains capacitors that remain charged to a potentially lethal voltage after AC
supply has been disconnected. Wait at least 10 minutes for the stored charge to
dissipate. See section 2.9.4 Stored charge .
1.4Mounting of Drive
The drive is designed to mount to a wall within a control panel or on a DIN rail. For
proper functioning, mount the drive with the minimum recommended clearances. See
Chapter 4.
1.5Wiring Motor
The IMC high performance motor can be wired as either 200 or 400 volts. Wire the
motor as 200V for the A Size IM-pAC and wire the motor as 400V for the B Size IMpAC. See section 5.1, Figure 5-1 and Figure 5-2.

1.7Wiring Power and Switches to Drive
1. Refer to Chapter 3 Rating Datafor all other fuse sizes and control and motor cable
wire sizes. Single phase can be obtained from a 3 phase "wye" by wiring two of the
"hots" (L1 and L2 or L2 and L3 or L1 and L3) to the drive. Do not remove internal
EMC filter. See Chapter 5.
2. The control terminal B2 outputs 24 volts DC and will be used to power the signals.
The control terminal B4 is used to enable the drive. As long as B2 and B4 are
connected the drive will run. Use a normally closed switch (not supplied by IMC) or
jumper between B2 and B4 to enable the drive. The control terminal B5 runs the
motor forward and B6 runs the motor in reverse. If the indexer is not turning in the
proper direction interchange B5 and B6.

3. Make sure the indexer is in the middle of its dwell position before starting or
stopping the motor. see section 1.16 Indexer drive shown in middle of dwell position diagram. on page 9.
4. The motor is made to run by closing the B2-B5 or B2-B6 terminals. Opening them
will stop the motor.
5. Cycling on demand using a limit switch and inverter duty motor. The normally closed
side of the cam shaft limit switch should be wired to terminals B2 and B5 (or B6).
When the indexer is in dwell the switch will be open. A start signal is sent by
momentarily closing B2 and B5 with an external switch. As the camshaft is turning
the limit switch on the cam shaft will close and thus maintain the B2-B5 (or B6)
closure. When the indexer enters dwell the trip cam on the cam shaft will cause the
limit switch to open the B2-B5 (or B6) connection and stop the motor.

1.24How to configure the IM-pAC drive to trip for a current ove r-
WARNING
load.
The current overload configuration will protect the index drive only and is not meant to
be a means of protecting any personnel or tooling. Always make sure that no person is
near the indexer and the indexer is clear of any obstructions before operating the drive
while testing the configuration settings or during normal operation.
Overview
The IM-pAC drive is factory preset to constantly monitor the current seen by the motor
and the drive will trip if the accumulated motor current values over time exceed a set
value. This is a calculation and does not require a wired motor themistor input.
The motor thermal constant parameter controls the drive trip and is set at a default value
of 89. The 89 value will allow the motor to draw 1.65 times its rated amperage for a little
over 40 seconds before the drive will trip. When the drive trips the drive healthy relay
(T5 and T6 contacts) will open to signal the trip. You will wire your PLC input line
through the drive healthy relay to signal the trip. When the drive is tripped the display
will show [It.AC]
The overload configuration scheme for the IM-pAC uses a thermal constant parameter
set to 1 (the minimum) and a symmetrical current value set for the application. Index
drives 601RDM and 902RDM have been tested at IMC using a thermal constant of 1
and a symmetrical current constant of 165. The drives successfully tripped without any
indexer damage for a jammed dwell or an obstruction encountered during the middle of
the index.
For now based upon our test results we are limiting use of this overload
configuration to applications under 1 horsepower demand.
The following steps describe how to view the torque required for you application and
how to change the symmetrical current and motor constant values to protect your
indexer from damage.
We are assuming that you have already entered in the correct parameter values for
Pr 39, Pr 06, Pr 08 and Pr 09 from your motor name plate.
We also assume you have placed the jumpers and wired your motor for the correct
applied voltage. Remember the control voltage must be greater than or equal to the
motor's voltage.
The instructions in this document are detailed and should be read carefully before
proceeding. In addition we have included as a reference on the last page of this paper a
page from the IM-pAC manual showing how to view and change parameters from the
keypad.
Parameters Used
ParameterDescription
Pr 10Security level - default is L1
Pr 88Current magnitude - current demand for your application
Pr 4.07Symmetrical current value - default is 165 percent
Pr 4.15Motor thermal constant - default is 89
The key pad display should show [ih 0.0] and not [rd 0.0] when you start. You must put
the control into inhibit mode by opening B2 and B4.
Press the M (memory) button on the key pad. The display will start to show the flashing
parameter numbers on the left side and the non-flashing parameter values on the right
side. Now, press the /\ button to the right of the M button several time until the left
parameter value changes to 10. If you happen to go passed Pr 10 then use the \/ key to
return to Pr 10. Once you are at the flashing Pr 10, press the M key and the parameter
value on the right L1 should start to flash.
Press the /\ key 2 times until a value of L3 appears [10 L3].
Press the M key 2 times to return the display back to [ih 0.0].
Step 2 - How to map the motor thermal constant to Pr 61.
Press the M button on the key pad. Now, press the \/ button until the left parameter
value changes to Pr 71. If you happen to go passed Pr 71, then use the /\ key to return
to Pr 71. Once you are at the flashing Pr 71, press the M key and the parameter value
on the right 0.0 should start to flash.
Press the /\ key several times until a value of 4.15 appears [71 4.15].
Press the M key 2 times to return the display back to the [ih 0.0].
Step 3 - How to map the symmetrical current value to Pr 62.
Press the M button on the key pad. Now, press the \/ button until the left parameter
value changes to Pr 72. If you happen to go passed Pr 72, then use the /\ key to return
to Pr 72. Once you are at the flashing Pr 72, press the M key and the parameter value
on the right 0.0 should start to flash.
Press the /\ key several times until a value of 4.07 appears [72 4.07].
Press the M key 2 times to return the display back to [ih 0.0].
Step 4 - How to view the current magnitude for your application.
See the Safety Warning on the first page before continuing.
The key pad display should show [rd 0.0] when you start. If the display shows [ih 0.0]
you must take the control out of inhibit mode by closing B2 and B4. Make sure you are
set to run at your intended speed and load. You will now run the motor continuously in
order to view and record the maximum current demand for your application. In order to
run the motor continuously you must keep connection B2 and B5 closed. You can do
this with a simple jumper. Once the motor and drive are running, press the M button on
the key pad. Now, press the \/ button until the left parameter value changes to Pr 88. If
you happen to go passed Pr 88, then use the /\ key to return to Pr 88. The maximum
value for Pr 88 is the maximum value for your application. You will use this amperage
value in step 6 as part of a calculation for the symmetrical current value.
Press the M key 2 times to return the display back to the [rd 0.0].
You can now remove the jumper between B2 and B5.
Step 5 - How to change the motor thermal constant Pr 61.
Press the M button on the key pad. Now, press the \/ button several times until the left
parameter value changes to Pr 61. If you happen to go passed Pr 61, then use the /\
key to return to Pr 61. Once you are at the flashing Pr 61, press the M key and the
parameter value on the right Pr 89 should start to flash.
Press the \/ key several times until a value of 1 appears [61 1].
Press the M key 2 times to return the display back to the [ih 0.0].

Step 6 - How to change the symmetrical current value Pr 62.
NOTE
NOTE
The new symmetrical current value is calculated by the following method.
Take the value of the maximum current value observed from step 4 and divide it by the
motor rated current value (Pr 06 or the name plate value) and then multiply it by 100.
e.g. XXX = 0.94 / 1.14 x 100 = 83
This means we would like the drive to fault at 83 percent of the motor rated current. We
may want to add a few percent to this to avoid some nuisance trips so we will round this
up to 100.
Never exceed a value of 165 for the symmetrical current or raise the value of Pr 06 above
the name plate value for the applied voltage.
Press the M button on the key pad. Now, press the \/ button several until the left
parameter value changes to Pr 62. If you happen to go passed Pr 62, then use the /\
key to return to Pr 62. Once you are at the flashing Pr 62, press the M key and the
parameter value on the right 0.0 should start to flash. Press the /\ key several times until
the value of XXX appears [62 XXX.0]. (For our revised calculated example we would
have entered 100 [62 100.0].) Press the M key 2 times to return the display back to the
[ih 0.0]. The drive has now been configured to trip during a current overload. You can
take the drive out of the inhibit state by closing connections B2 and B4.
How to manually recover from an overload.
See the Safety Warning on the first page before starting this step.
You must put the control into inhibit mode by opening B2 and B4.
You must recover from the overload condition by returning the indexer to a dwell
position at a reduced speed. You can reduce the motor speed by either changing Pr 18
or turning the speed pot down if you have one wired.
Press the button on the key pad with the red circle.
Put the control out of inhibit mode by closing B2 and B4. If the index drive does not start,
then send a start signal. Once you are in a dwell position reset the motor preset value
back to its original value or return the speed pot back to its normal setting.
1.25Drive parameter list for a motor reversing application
You should have a copy of the data sheet for the indexer application in order to set Pr 18
correctly. You must change Pr 10 (Security Level) to 2 or L3 before you can change
Pr 18, the preset speed. On the data sheet you will find the motor speed for your
application and the motor's rated rpm.
Use the following calculation to determine Pr 18.
Pr 18 = Pr 39 x Motor Speed for Application / Motor Rated RPM
Pr 18 = 60 hz x 1650 rpm / 1750 rpm = 57 hz (round all values up to a whole number)

98/37/EC: Safety of machinery
89/336/EEC: Electromagnetic compatibility
2.7Motor
Ensure the motor is installed in accordance with the manufacturer's recommendations.
Ensure the motor shaft is not exposed.
Standard squirrel cage induction motors are designed for single speed operation. If it is
intended to use the capability of a drive to run a motor at speeds above its designed
maximum, it is strongly recommended that the manufacturer is consulted first.
Low speeds may cause the motor to overheat because the cooling fan becomes less
effective. The motor should be installed with a protection thermistor. If necessary, an
electric force vent fan should be used.
The values of the motor parameters set in the drive affect the protection of the motor.
The default values in the drive should not be relied upon.
It is essential that the correct value is entered into parameter 06, motor rated current.
This affects the thermal protection of the motor.
2.8Adjusting parameters
Some parameters have a profound effect on the operation of the drive. They must not
be altered without careful consideration of the impact on the controlled system.
Measures must be taken to prevent unwanted changes due to error or tampering.

2.9Electrical installation
2.9.1 Electric shock risk
The voltages present in the following locations can cause severe electric shock and may
be lethal:
•AC supply cables and connections
•DC bus, dynamic brake cables and connections
•Output cables and connections
•Many internal parts of the drive, and external option units
Unless otherwise indicated, control terminals are single insulated and must not be
touched.
The AC supply must be disconnected from the drive using an approved isolation device
before any cover is removed from the drive or before any servicing work is performed.
2.9.3 STOP function
The STOP function does not remove dangerous voltages from the drive, the motor or
any external option units.
2.9.4 Stored charge
The drive contains capacitors that remain charged to a potentially lethal voltage after the
AC supply has been disconnected. If the drive has been energized, the AC supply must
be isolated at least ten minutes before work may continue.
Normally, the capacitors are discharged by an internal resistor. Under certain, unusual
fault conditions, it is possible that the capacitors may fail to discharge, or be prevented
from being discharged by a voltage applied to the output terminals. If the drive has failed
in a manner that causes the display to go blank immediately, it is possible the capacitors
will not be discharged. In this case, consult IMC or their authorized distributor.
2.9.5 Equipment supplied by plug and socket
Special attention must be given if the drive is installed in equipment which is connected
to the AC supply by a plug and socket. The AC supply terminals of the drive are
connected to the internal capacitors through rectifier diodes which are not intended to
give safety isolation. If the plug terminals can be touched when the plug is disconnected
from the socket, a means of automatically isolating the plug from the drive must be used
(e.g. a latching relay).
2.9.6 Ground leakage current
The drive is supplied with an internal EMC filter capacitor installed. If the input voltage to
the drive is supplied through an ELCB or RCD, these may trip due to the ground
leakage current. See section 5.3.1 Internal EMC filter on page 41 for further information
Output frequency: 0 to 1500Hz
Output voltage: 3 phase, 0 to drive rating (240 or 480Vac maximum set by Pr 08).
The output voltage can be increased by 20% during deceleration. See Pr 30 on page 60
NOTE
The maximum continuous current inputs are used to calculate input cable and fuse
sizing. Where no maximum continuous input currents are indicated, use the typical full
load input current values.

Enclosure
The drive is intended to be mounted in an enclosure which prevents access except by
trained and authorized personnel, and which prevents the ingress of contamination. It is
designed for use in an environment classified as pollution degree 2 in accordance with
IEC 60664-1. This means that only dry, non-conducting contamination is acceptable.

If DIN rail mounting is used in an installation where the drive is to be subjected to shock
or vibration, it is recommended that the bottom mounting screws are used to secure the
drive to the back plate.
If the installation is going to be subjected to heavy shock and vibration, then it is
recommended that the drive is surface mounted rather than DIN rail mounted.
The DIN rail mounting mechanism has been designed so no tools are required to install
and remove the drive from a DIN rail. Please ensure the top mounting lugs are located
correctly on the DIN rail before installation is initiated.
*For further information, see section 5.3.1 Internal EMC filter on page 41.
On the size B 110V drives, the supply should be connected to L1 and L3/N.

NOTE
NOTE
NOTE
The AC supply to the drive must be installed with suitable protection against overload
and short circuits. Failure to observe this requirement will cause risk of fire.
The drive must be grounded by a conductor sufficient to carry the prospective fault
current in the event of a fault. See also the warning in section 5.2 Ground leakage
relating to ground leakage current.
To avoid a fire hazard and maintain validity of the UL listing, adhere to the specified
tightening torques for the power and ground terminals. Refer to the table below.

B and C1.4 N m / 12.1 lb in
Braking resistor: High temperatures and overload protection
Braking resistors can reach high temperatures. Locate braking resistors so that damage
cannot result. Use cable having insulation capable of withstanding the high temperatures.
It is essential that the braking resistor be protected against overload caused by a failure
of the brake control. Unless the resistor has in-built protection, a circuit like those shown
Figure 5-1
in
and
Figure 5-2
should be used, where the thermal protection device
disconnects the AC supply to the drive. Do not use AC relay contacts directly in series
with the braking resistor circuit, because it carries DC.
When connecting single phase to a dual rated 200V unit, use terminals L1 and L3.
For control terminal connections, see Pr 05 on page 51.
For information on the internal EMC filter, see section 5.3.1 Internal EMC filter .
5.2Ground leakage
The ground leakage current depends upon the internal EMC filter being installed. The
drive is supplied with the filter installed. Instructions for removal of the internal EMC filter
are given in section 5.3.2 Removing the internal EMC filter .

<1mA
In both cases, there is an internal voltage surge suppression device connected to
ground. Under normal circumstances, this carries negligible current.
When the internal EMC filter is installed, the leakage current is high. In this case, a
permanent fixed ground connection must be provided using two independent conductors
each with a cross-section equal to or exceeding that of the supply conductors. The drive
is provided with two ground terminals to facilitate this. The purpose is to prevent a safety
hazard occurring if a connection is lost. Both ground connections are required to meet
the required european standard.
5.2.1 Use of earth (ground ) leakage circuit breakers (ELCB) / residual current
device (RCD)
There are three common types of ELCB/RCD:
Type AC - detects AC fault currents
Type A - detects AC and pulsating DC fault currents (provided the DC current
reaches zero at least once every half cycle)
Type B - detects AC, pulsating DC and smooth DC fault currents
•Type AC should never be used with drives
•Type A can only be used with single phase drives
•Type B must be used with three phase drives
5.3EMC
5.3.1 Internal EMC filter
It is recommended that the internal EMC filter is kept in place unless there is a specific
reason for removing it.
If the drive is to be used on an IT supply, then the filter must be removed.
The internal EMC filter reduces radio-frequency emissions into the mains supply. Where
the motor cable is short, it permits the requirements of EN61800-3 to be met for the
second environment.
For longer motor cables, the filter continues to provide a useful reduction in emission
level, and when used with any length of shielded cable up to the limit for the drive, it is
unlikely that nearby industrial equipment will be disturbed. It is recommended that the
filter be used in all applications unless the ground leakage current is unacceptable or
the above conditions are true.
Figure 5-3 Removal and re-fitting of internal EMC filter
5.3.3 Further EMC precautions
Further EMC precautions are required if more stringent EMC emission requirements
apply:
•Operation in the first environment of EN 61800-3
•Conformity to the generic emission standards
•Equipment which is sensitive to electrical interference operating nearby
In this case it is necessary to use:
•The optional external EMC filter
•A shielded motor cable, with screen clamped to the grounded metal panel
•A shielded control cable, with screen clamped to the grounded metal panel
Full instructions are given in the IM-pAC Technical Data Guide.
A full range of external EMC filters is also available for use with IM-pAC.
5.4Control terminals I/O specification
The control circuits are isolated from the power circuits in the drive by basic insulation
(single insulation) only. The installer must ensure that the external control circuits are
insulated from human contact by at least one layer of insulation (supplementary
insulation) rated for use at the AC supply voltage.
42IM-pAC Getting Started Guide
If the control circuits are to be connected to other circuits classified as Safety Extra Low
Voltage (SELV) (e.g. to personal computer), an additional isolating barrier must be
included in order to maintain the SELV classification.
The above warnings also apply to the PCB edge connector for the optional Solutions

NOTE
Modules. To allow a Solutions Module to be installed with an IM-pAC, a protective cover
must be removed to allow access to the PCB edge connector. See Figure 4-3 on page 38.
This protective cover provides protection from direct contact of the PCB edge connector by
the user. When this cover is installed and a Solutions Module fitted, the Solutions Module
provides the protection from direct contact by the user. If the Solutions Module is then
removed, this PCB edge connector becomes exposed. The user is required to provide
protection in this case, to protect against direct contact of this PCB edge connector.

If the enable terminal is opened, the drive’s output is disabled and the motor will coast to
a stop. The drive will not re-enable for 1.0s after the enable terminal is closed again.
*Following a drive trip, opening and closing the enable terminal will reset the drive. If the
run forward or run reverse terminal is closed, the drive will run straight away.
**Following a drive trip and a reset via the stop/reset key, the enable, run forward or run
reverse terminals will need to be opened and closed to allow the drive to run. This
ensures that the drive does not run when the stop/reset key is pressed.
The enable, run forward and run reverse terminals are level triggered apart from after a
trip where they become edge triggered. See * and ** above.
If the enable and run forward or enable and run reverse terminals are closed when the
drive is powered up, the drive will run straight away up to a set speed.
If both the run forward and run reverse terminals are closed, the drive will stop under the
control of the ramp and stopping modes set in Pr 30 and Pr 31.
This procedure is written from the first power up of the drive and assumes no terminals
have been connected, no parameters have been changed and no security has been set.

Keypad and Display
When in Status mode, pressing and holding the MODE key for 2 seconds will
change the display from displaying a speed indication to displaying load indication and
vice versa.
Pressing and releasing the MODE key will change the display from status mode to
parameter view mode. In parameter view mode, the left hand display flashes the
parameter number and the right hand display shows the value of that parameter.
Pressing and releasing the MODE key again will change the display from parameter
view mode to parameter edit mode. In parameter edit mode, the right hand display
flashes the value in the parameter being shown in the left hand display.
Pressing the MODE key in parameter edit mode will return the drive to the
parameter view mode. If the MODE key is pressed again then the drive will return to
status mode, but if either of the up or down keys are pressed to change the
parameter being viewed before the MODE key is pressed, pressing the MODE
key will change the display to the parameter edit mode again. This allows the user to
very easily change between parameter view and edit modes while commissioning the
drive.

Parameters are automatically saved when the MODE key is pressed when going
from parameter edit mode to parameter view mode.
6.5Parameter access
There are 3 levels of parameter access controlled by Pr 10. This determines which
parameters are accessible. See Table 6-1.
The setting of the user security Pr 25 determines whether the parameter access is read
only (RO) or read write (RW).

6.6Security codes
Setting a security code allows view only access to all parameters.
A security code is locked into the drive when Pr 25 is set to any other value than 0 and
then LoC is selected in Pr 10. On pressing the MODE key, Pr 10 is automatically
changed from LoC to L1 and Pr 25 will be automatically set to 0 so as not to reveal the
security code.
Pr 10 may be changed to L2 or L3 to allow view only access to parameters.
The drive is enabled and ready for a start command. The
output bridge is inactive.
The drive is inhibited because there is no enable command,
or a coast to stop is in progress or the drive is inhibited during
a trip reset.
The drive has tripped. The trip code will be displayed in the
right hand display.
•Pr 10 will now be reset to L1 and Pr 25 will be reset to 0.
•The security code will now be locked into the drive.
•Security will also be set if the drive is powered down after a security code has been
set into Pr 25.
6.6.2 Unlocking a security code
•Select parameter to be edited
•Press the MODE key, the right hand display will flash 'CodE'
•Press the UP key to start entering the set security code. The left hand display
will show 'Co'
•Enter the correct security code
•Press the MODE key
•If the correct security code has been entered, the right hand display will flash and
can now be adjusted.
•If the security code has been entered incorrectly, the left hand display will flash the
parameter number. The above procedure should be followed again.
6.6.3 Re-locking security
When a security code has been unlocked and the required parameter changes made, to
re-lock the same security code:
•Set Pr 10 to LoC
•Press the MODE key

The SmartStick can be used to copy parameters between drives of different ratings.
Certain drive dependant parameters will be stored on the SmartStick but will not be
copied to the cloned drive.
The drive will trip on C.rtg when being written to by a copied parameter set of a different
drive rating.
The drive dependant parameters are: Pr 06 Motor rated current, Pr 08 Motor rated
voltage, Pr 09 Motor power factor and Pr 37 Maximum switching frequency.
Before the SmartStick /LogicStick is written to using Prog, the SmartStick/LogicStick will
need to be inserted into the drive at power up or a reset command performed when the
drive has been powered up, otherwise will trip on C.dAt when Prog command executed.
For best motor performance, an autotune should be carried out after parameter copying
has taken place.
When copying between drives of different ratings, bit parameters will not be copied.
no: defaults are not loaded
Eur: 50Hz default parameters are loaded
USA: 60Hz default parameters are loaded
Default parameters are set by pressing the MODE key on exit from parameter edit
mode after Pr 29 has been set to Eur or USA.
When default parameters have been set, the display will return to Pr 01 and Pr 10 will be
reset to L1.
The drive must be in a disabled, stopped or tripped condition to allow default parameters
to be set. If default parameters are set while the drive is running, the display will flash
FAIL once before changing back to no.

Pr 61 to Pr 70 and Pr 71 to Pr 80 can be used to access and adjust advanced
parameters.
Example: It is desired that Pr 1.29 (Skip frequency 1) is to be adjusted. Set one of the
parameters Pr 71 to Pr 80 to 1.29, the value of Pr 1.29 will appear in the corresponding
parameter from Pr 61 to Pr 70. I.e. if Pr 71 is set to 1.29, Pr 61 will contain the value of
Pr 1.29 where it can be adjusted.
Some parameters are only implemented if the drive is disabled, stopped or tripped and
the STOP/RESET key is pressed for 1s.
Set Pr 71 to Pr 80 to the required advanced parameter number to be accessed.
The value within these parameters will be displayed in Pr 61 to Pr 70. Pr 61 to Pr 70 can
then be adjusted to change the value within a parameter.
