Table A-1: Fault Codes (Continued)
ᕃ
Programmable.
ᕄ
“A” faults only.
Load Test with Motor
1. Connect the motor cables and check the right phase order. Also check that the motor
rotates freely.
2. Check liquid cooling system operation
3. Turn on the supply voltage and ensure that all input phases are connected to the unit.
4. Check DC link voltage by measuring with multimeter and compare the value to the one
on monitoring page V1.8.
5. Select the application of your choice and set the needed parameters.
6. Start the operation with lower Current Limit value and long Acceleration/Deceleration
times.
7. If Closed Loop control mode is used, check direction of encoder and make necessary
Closed Loop parameter settings. Check the correct operation of the encoder by running
the system in open loop and check the signals in the expander board menu.
8. Run the motor without load between minimum and maximum frequencies and check
the unit output current with a current clamp. Compare the value to the one on
monitoring page V1.4.
9. Load the motor to nominal value if possible and repeat the current measurement.
Follow the Unit Temperature value on page V1.9.

50 Analog input
sel. signal range
4 to 20 mA)
ᕃ
Current at the analog input is
<4 mA.
• control cable is broken or loose
• signal source has failed.
Check the current loop, signal source
and wiring.
51 External fault Digital input failed. Check source of trigger.
52 Keypad
communication
fault
There is no connection between the
control keypad and the drive.
Check the keypad connection and
keypad cable.
53 Fieldbus fault The data connection between the
fieldbus master and the fieldbus
board is broken.
Check installation.
If installation is correct contact your
Cutler-Hammer distributor.
54 Slot fault Defective option board or slot. Check that the board is properly
installed and seated in slot. If the
installation is correct, contact your
Cutler-Hammer distributor.
56 PT100 board
temperature fault
Temperature limit values set for the
PT100 board parameters have been
exceeded.
Determine the cause of the high
temperature.
