Connect the drive and peripheral devices as shown in
, and
. It is possible
to set and run the drive via the digital operator without connecting digital I/O wiring. This section does not discuss drive
operation;
Refer to Start-Up Programming & Operation on page 131
for instructions on operating the drive.
Models CIMR-U

0720 to 4
0930 need main circuit wiring and connecting with the module communications
connector. Refer to
Module Communications Connector on page 108
for details.
WARNING!
Sudden Movement Hazard. Do not close the wiring for the control circuit unless the multifunction input terminal
parameters are properly set. Improper sequencing of run/stop circuitry could result in death or serious injury from moving equipment.
WARNING!
Sudden Movement Hazard. Ensure start/stop and safety circuits are wired properly and in the correct state before
energizing the drive. Failure to comply could result in death or serious injury from moving equipment. When programmed for 3-Wire
control, a momentary closure on terminal S1 may cause the drive to start.
WARNING!
Sudden Movement Hazard. When using a 3-Wire sequence, set the drive to 3-Wire sequence prior to wiring the control
terminals and set parameter b1-17 to 0 so the drive will not accept a Run command at power up (default). If the drive is wired for a
3-Wire sequence but set up for a 2-Wire sequence (default), and parameter b1-17 is set to 1 so the drive accepts a Run command at
power up, the motor will rotate in reverse direction at drive power up and may cause injury.
WARNING!
Sudden Movement Hazard. Confirm the drive I/O signals and external sequence before executing the application preset
function. Executing the application preset function or setting A1-06
≠
0 will change the drive I/O terminal functions and may cause
unexpected equipment operation. Failure to comply may cause death or serious injury.
WARNING!
When using the automatic fault restart function with wiring designed to shut off the power supply upon drive fault, make
sure the drive does not trigger a fault output during fault restart (L5-02 = 0, default). Failure to comply will prevent the automatic fault
restart function from working properly.
NOTICE:
Inadequate wiring could result in damage to the drive. Install adequate branch circuit protection per applicable codes. The
drive is suitable for circuits capable of delivering not more than 100,000 RMS symmetrical amperes, 240 Vac maximum (200 V Class),
480 Vac maximum (400 V Class: CIMR-U
4E
/4W
), and 500 Vac maximum (400 V Class: CIMR-U
4A
/
4P
).
NOTICE:
When the input voltage is 440 V or higher or the wiring distance is greater than 100 meters, pay special attention to the
motor insulation voltage or use a drive duty motor. Failure to comply could lead to motor insulation breakdown.
NOTICE:
Do not connect AC control circuit ground to drive enclosure. Improper drive grounding can cause control circuit malfunction.
NOTICE:
The minimum load for the multi-function relay outputs M1-M2, M3-M4, M5-M6, and MA-MB-MC is 10 mA. If a circuit requires
less than 10 mA (reference value), connect it to a photocoupler output (P1, P2, PC). Improper application of peripheral devices could
result in damage to the photocoupler output of the drive.
NOTICE:
Correctly set Sink/Source jumper S3 for internal power supply. Failure to comply may result in damage to the drive. Refer to
Control I/O Connections on page 110
for details.
NOTICE:
Create a sequence to shut off power on the power supply side by using a fault relay output as shown in the standard
connection diagram, or create a sequence that prevents the motor shaft from being turned by an external force. If you continue to input
power from a power supply with a large distortion or if an external force causes the motor shaft to continue turning even after an SoH
(Snubber Discharge Resistor Overheat) occurs, the snubber resistor may break.
NOTICE:
Do not connect more than one multi-function input to one terminal. Improper wiring may result in drive malfunction. Use an
external power supply when sharing a terminal with more than one input. Do not use the built-in +24 V power supply.
NOTICE:
Systems should be interlocked to shut off power to the drive if the drive experiences a fault for models CIMR-U
4
0477 to
4
0930. Refer to
External Interlock on page 127
for details.
