Table A-1: Fault Codes (Continued)
ᕃ Programmable.
ᕄ “A” faults only.
Fault
Code Fault
Possible Cause Solution
29 Thermistor fault ᕃ The thermistor input of option board
has detected increase of the motor
temperature. Check motor cooling and loading
Check thermistor connection
(If thermistor input of the option
board is not in use, it has to be short
circuited)
31 IGBT temperature
(hardware) IGBT Inverter Bridge
overtemperature protection has
detected too high a short term
overload current. Check loading.
Check motor size.
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 can not control Power
Unit and vice versa. Change control unit.
37 Device change
(same type)
ᕄ
• option board or control unit
changed.
• same type of board or same
power rating of drive
Reset
Note: No fault time data record!
38 Device added
(same type)
ᕄ
• option board or drive added.
• drive of 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 too high a short term
overload current. Check loading.
Check motor size.
42 Brake resistor
overtemperature
ᕃ
Brake resistor overtemperature
protection has detected too heavy
braking. Set the deceleration time longer.
Use external brake resistor.
43 Encoder fault Note: the exceptional fault data
record, see 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 changed
(different type)
ᕄ
• option board or control unit
changed
• option board of different type or
different power rating of drive
Reset.
Note: No Fault Time Data Record is
made.
Note: Application parameter values
restored to default.
