 Error codes

 

 

 

 

GF 

Fault name : Ground Fault

• Current shorted to ground esceeded 50% of rated current on output side of the drive.

• Setting L8-09 to 1 enables ground fault detection in models 2A0020 to 2A0069 and 4A0011 to 4A0038.

Cause : Motor insulation is damaged

Possible solution : Check the insulation resistance of the motor.

                                   Replace the motor.

LF

Fault name : Output Phase Loss

• Phase loss on the output side of the drive.

• Phase loss detection is enabled when L8-07 is set to 1 or 2.

Cause1 : The output cable is disconnected

Possible solution : Check for wiring errors and ensure the output cable is connected properly.

                                  Correct the wiring.

Cause2 : The motor winding is damaged.

Possible solution : Check the resistance between motor lines.

                                  Replace the motor if the winding is damaged.

Cause3 : The output terminal is loose.

Possible solution: Apply the tightening torque specified in the manual to fasten the terminals. Refer to Wire Size and Torque Specifications on page 66.

Cause4 : The motor being used in less than 5% of the drive rated current.

Possible solution : Check the drive and motor capacities.

Cause5 : An output transistor is damaged.

Possible solution : Replace the drive.

Cause6 : A single-phase moto ris being used.

Possible solution : The drive being used cannot operate a single phase motor.

rr

Fault name : Dynamic Braking Transistor

                       The built-in dynamic braking transistor failed.

Cause1 : The braking transistor is damaged.

Possible solution : Cycle power to the drive and check if the fault reoccurs. Refer to Diagnosing and Resetting Faults on page 298.

                                  Replace the drive if the fault continues.

Cause2 : The control circuit is damaged.

Possible solution : Cycle power to the drive and check if the fault reoccurs. Refer to Diagnosing and Resetting Faults on page 298.

                                  Replace the drive if the fault continues.
