Causes and Solutions

】

Causes

Solutions

Wrong servo motor output wiring

Correct the wiring of power cables (U, V and W).

Check cables visually or through continuity check and replace the

defective cable.

Short circuit or grounding fault in

Servo motor output wiring

Servo motor insulation fault

Measure the insulation resistance. (Several MΩ or over to ground)

Failure of servomotor

Measure the resistance across cables

. (Several Ω between cables)

Incorrect resistance of regenerative

resistor

Replace with the regenerative resistor within the rating.

Current imbalance caused by an

encoder fault

Replace the servo motor

Unconnected grounding cable

Connect the grounding cable
