12.10.101 Fault 42 - Brake resistor overtemperature, Subcode S3 - Brake resistance too low (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.
12.10.102 Fault 42 - Brake resistor overtemperature, Subcode S4 - Brake resistance not detected
(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.
12.10.103 Fault 42 - Brake resistor overtemperature, Subcode S5 - Brake resistance leakage (earth
fault) (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.
12.10.104 Fault 43 - Encoder fault, Subcode S1 - Encoder 1 channel A is missing
Cause
Problem detected in encoder signals.
Encoder channel A is missing.
Troubleshooting
Do a check of the encoder connections.
Do a check of the option board.
Measure the encoder pulses.
If the pulses are correct, the option board is faulty.
If the pulses are not correct, the encoder/cabling is faulty.
12.10.105 Fault 43 - Encoder fault, Subcode S2 - Encoder 1 channel B is missing
Cause
Problem detected in encoder signals.
Encoder channel B is missing.
