12.10.108 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.
12.10.109 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.
12.10.110 Fault 43 - Encoder fault, Subcode S8 - Resolver/Motor pole pair mismatch
Cause
Problem detected in parameterization of option board.
There is a mismatch of the resolver/ motor pole pair number. Resolver pole pair number (if >1) is not matching the motor pole pair
number.
Troubleshooting
Check that OPTBC parameter “Resolver Poles” and possible Gear Ratio parameters in application match motor pole count.
12.10.111 Fault 43 - Encoder fault, Subcode S9 - Missed Start Angle
Cause
Encoder zero positioning identification run has not been made.
The encoder start angle is missing.
Troubleshooting
Make encoder identification run.
