by external noise. See the chapter on noise
reduction in ”Connection.”

ground and each of U, V, and W. If the insulation is satisfactory, go to (5).
If a short–circuit is detected, disconnect the power line from the motor connector. Then, check
the insulation between the ground and each of U, V, and W of the motor.
If a short–circuit is found between the ground and U, V, or W of the motor, replace the motor.
If the insulation is satisfactory, replace the power line.
