What to do if Mitsubishi Electric FR-A500L Inverter shows output over current?
- MMary RichAug 23, 2025
If the Mitsubishi Electric Inverter indicates an output over current, it could be due to several reasons: * An output short circuit or ground fault (check the motor winding and insulation resistance). * Rapid acceleration or deceleration. * Sudden load fluctuations. * Mechanical brakes applied too quickly. To address this, repair any output short circuits or ground faults, lengthen the acceleration and deceleration times, eliminate sudden load fluctuations, and investigate the braking operation.
