Common Failures
Units have been reported with issues such as non-operation in the reverse direction and partial wave operation in the forward direction. These problems have generally been linked to defective components within the pulse transformer drivers and intermittent connections.
Repair Approach
Repairs have involved the replacement of defective driver components responsible for pulse transformer operation. Additionally, repairing intermittent connections at critical points has been necessary to address these operational issues. Resoldering connections and replacing faulty parts have restored functionality in both directions.
Testing & Quality
Repaired units undergo comprehensive diagnostic testing to verify that both forward and reverse operations are restored. Successful cycling of the motor in both directions validates the repairs. Units are confirmed to be fully operational after testing.
