E.Syn fault in KEB COMBIVERT R6 Drive indicates a synchronization error. This means the line frequency was calculated incorrectly due to swapped or improper phasing at the commutation choke.
Cause:
Line frequency calculated incorrectly.
Remedy:
If the value in CP.02 is negative, swap L1.1 and L2.1 at the commutation choke so that CP.02 is positive.
