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.
12.10.106 Fault 43 - Encoder fault, Subcode S3 - Both encoder 1 channels are missing
Cause
Problem detected in encoder signals.
Encoder channels A and B are 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.
12.10.107 Fault 43 - Encoder fault, Subcode S4 - Encoder reversed
Cause
Problem detected in encoder signals.
The encoder is reversed. The output frequency has been set to the positive value, but the encoder signal is negative.
Troubleshooting
Change the frequency value polarity so that the encoder signal is positive. With some encoders, interchanging the encoder chan-
nels can be used to change the indicated rotation direction.
12.10.108 Fault 43 - Encoder fault, Subcode S5 - Encoder board missing
Cause
The encoder board is missing.
Troubleshooting
Do a check of the encoder board.
Do a check of the terminals.
Do a check of the board connections.
12.10.109 Fault 43 - Encoder fault, Subcode S6 - Serial communication fault
Cause
Problem detected in encoder signals.
Serial communication fault. The encoder cable is not connected or there are interferences in the cable.
Troubleshooting
Check cabling between encoder and OPTBE, especially Data and Clock signals.
Check that actual encoder type matches with OPTBE “Operating mode” parameter.
12.10.110 Fault 43 - Encoder fault, Subcode S7 - Ch A / Ch B Mismatch
Cause
Problem detected in encoder signals.
Encoder channels A and B are mismatched.
Troubleshooting
Do a check of the cable connections and terminals.
12.10.111 Fault 43 - Encoder fault, Subcode S8 - Resolver/Motor pole pair mismatch
Cause
Problem detected in parameterization of option board.
