How to fix overcurrent in Mitsubishi Electric Amplifier?
To resolve an overcurrent issue in your Mitsubishi Electric Amplifier: * Ensure that there are no shorts in the servo amplifier output phases U, V, and W, and correct the wiring if needed. * If the transistor of the servo amplifier is faulty (Alarm (32) occurs if power is switched on after U,V and W are disconnected), replace the servo amplifier. * Correct the wiring if a ground fault occurred in servo amplifier output phases U, V, and W. * Implement noise suppression measures to address external noise causing the overcurrent detection circuit to misoperate. * For MR-J2S-500B models, ensure proper wiring of the regenerative brake option if the current is higher than the permissible current in the regenerative brake transistor.
