Hardware fault
1. Press “RESET” key to go back to the default. If bF still occurs
factory for repair.
2. Power off the motor drive since the internal circuit is abnormal.
to check if it is short-circuit between B2 to DC-. If short-circuit occurs
to the factory for repair.
Malfunction caused by
interference
Verify wiring/grounding of the main circuit to prevent interference.
Using the incorrect brake resistor Check if the resistance value of the brake resistor matches to the drive.
