Troubleshooting
Check the load.
Check the motor frame size.
Make an identification run.
12.10.96 Fault 41 - IGBT temperature, Subcode S4 - Peak current too high
Cause
IGBT Inverter Bridge overtemperature protection has detected too high a short-term overload current.
Troubleshooting
Check the load.
Check the motor frame size.
Make an identification run.
12.10.97 Fault 41 - IGBT temperature, Subcode S5 - BCU: Filtered current too high for some time
Cause
IGBT Inverter Bridge overtemperature protection has detected too high a short-term overload current.
Troubleshooting
Check the load.
Check the motor frame size.
Make an identification run.
12.10.98 Fault 41 - IGBT temperature, Subcode S6 - BCU: Current momentarily too high
Cause
IGBT Inverter Bridge overtemperature protection has detected too high a short-term overload current.
Troubleshooting
Check the load.
Check the motor frame size.
Make an identification run.
Check brake resistor resistance.
12.10.99 Fault 42 - Brake resistor overtemperature, Subcode S1 - Internal brake chopper overtem-
perature
Cause
Brake resistor overtemperature protection has detected too heavy braking.
Troubleshooting
Reset unit.
Set the deceleration time longer.
Dimensioning of the brake chopper is not correct.
Use external brake resistor.
12.10.100 Fault 42 - Brake resistor overtemperature, Subcode S2 - Brake resistance too high (BCU)
Cause
Brake resistor overtemperature protection has detected too heavy braking.
Troubleshooting
Reset unit.
Set the deceleration time longer.
Dimensioning of the brake chopper is not correct.
Use external brake resistor.
