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.
12.10.104 Fault 43 - Encoder fault, Subcode S2 - Encoder 1 channel B is missing
Cause
Problem detected in encoder signals.
Encoder channel B 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 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.
12.10.106 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.
