Table A-1: Fault Codes (Continued)
ᕃ
Programmable.
ᕄ
“A” faults only.
Fault
Code Fault Possible Cause Solution
31 IGBT Temperature
(hardware)
IGBT inverter bridge
overtemperature protection detected
a short term overload current that is
too high.
Check loading.
Check motor size.
32 Fan Cooling Cooling fan of the inverter does not
start, when ON command is given.
Contact your Cutler-Hammer
distributor.
34 CAN Bus
Communication
Sent message not acknowledged. Ensure that there is another device
on the bus with the same
configuration.
36 Control Unit Control unit cannot control power
unit and vice versa.
Change control unit.
37 Device Change
(same type)
ᕄ
• Option board or control unit
changed
• Option board of different type or
drive with different power rating
Reset
Note: No fault time data record.
38 Device Added
(same type)
ᕄ
• Option board or drive added
• Drive with same power rating or
same type of board added
Reset
Note: No fault time data record.
39 Device Removed
ᕄ
• Option board removed
• Drive removed
Reset
Note: No fault time data record.
40 Device Unknown Unknown option board or drive. Contact your Cutler-Hammer
distributor.
41 IGBT Temperature IGBT Inverter Bridge
overtemperature protection has
detected a short term overload
current that is too high.
Check loading.
Check motor size.
42 Brake Resistor
Overtemperature
ᕃ
Brake resistor overtemperature
protection detected braking that is
too heavy.
Set the deceleration time longer.
Use external brake resistor.
43 Encoder Fault Note: See the exceptional fault data
record on Page 5-12. Additional
codes:
1 = Encoder 1 channel A is missing
2 = Encoder 1 channel B is missing
3 = Both encoder 1 channels are
missing
4 = Encoder reversed
Check encoder channel connections.
Check the encoder board.
44 Device Change
(different type)
ᕄ
• Option board or control unit
changed
• Option board of different type or
drive with different power rating
Reset.
Note: No fault time data record is
made.
Note: Application parameter values
restored to default.
45 Device Added
(different type)
ᕄ
• Option board or device added
• Option board of different type or
drive with different power rating
added
Reset.
Note: No fault time data record is
made.
Note: Application parameter values
restored to default.
