1.1 Data Sheet
You will need a copy of the data sheet your sales representative provided you for your
application. You will need to refer to the data sheet in order to set motor speeds and
dwell times.
1.2 Drive Size
You will need to determine which size drive you have for proper mounting and wiring.

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.
1.3 Safety
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 .
1.4 Mounting 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.
1.5 Wiring 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.

1.7 Wiring 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

WARNING
The IM-pAC drive is delivered to you programmed for the 1/3 hp 230V 60 hz motor (IMC
Pt. No 92C49952070000). For a different motor rated frequency, amperage, voltage or
power factor you must change the motor parameters Pr 39, Pr 06, Pr 08 and Pr 09.
Below is a chart of the values for all the possible configurations of the standard IMC
motors. If you are not using an IMC motor then you must read these values from the
motor name plate. See section 6.3 Selecting and changing parameters on page 47 for
how to edit the parameter values.

1.9 Speed Control
Never auto tune the motor
You must now determine how you wish to control the maximum speed for your
application.
You can use a single preset speed parameter, or use an external potentiometer, or use
a potentiometer and 3 other preset speeds, or use a PLC to control speed. Please refer
to one of the four parameter list sections for the additional parameter changes for the
speed control you require for your application.

1.11 Brake Motors
See "24V brake motor - wiring and parameters" section.
1.12 Reversing the Motor
See "Reversing the motor direction - wiring and parameters" section.
1.13 Emergency Stop Safety
It is recommended that you purchase a commercial safety relay and motor contactor
product from a vendor such as Schneider Electric, Square D, Telemecanique or Phoenix
Contact that complies with the OSHA, ANSI or IEC safety directives you are required to
follow.
The drive must be disabled (open the B2 - B4 connection) before the motor contactors
are opened. Failure to do so will damage the drive.
1.14 Warranty and Return Policy
The IM-pAC Drive is warranted for 1 year from date of receipt. For technical support call
CAMCO-FERGUSON (847-215-5658).
1.15 Disposal

1.24 How 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
Parameter Description
Pr 10 Security level - default is L1
Pr 88 Current magnitude - current demand for your application
Pr 4.07 Symmetrical current value - default is 165 percent
Pr 4.15 Motor 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.
