12.12.90 Fault 40 - Device unknown, Subcode S6 - Old power unit (Asic) and new software mis-
match
Cause
An unknown or mismatching device was connected (the power unit or option board).
Troubleshooting
Ask instructions from the local distributor.
12.12.91 Fault 40 - Device unknown, Subcode S7 - Old ASIC detected
Cause
An unknown or mismatching device was connected (the power unit or option board).
Troubleshooting
Ask instructions from the local distributor.
12.12.92 Fault 41 - IGBT temperature, Subcode S1 - Calculated IGBT temperature 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.
12.12.93 Fault 41 - IGBT temperature, Subcode S3 - Calculated IGBT temperature too high (long-
term protection)
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.
12.12.94 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.
12.12.95 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.
12.12.96 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.
