What causes watchdog error on Mitsubishi Electric MR-J2S-350B?
Change servo amplifier if there is a fault of parts in servo amplifier. Alarm (88) occurs if power is switched on after disconnection of all cable but the control circuit power supply cable.
What does memory error 1 mean on Mitsubishi Electric MR-J2S-350B?
Change the servo amplifier if there are faulty parts in the servo amplifier. Alarm (any of 12 and 13) occurs if power is switched on after disconnection of all cables but the control circuit power supply cables.
How to fix memory error 3 on Mitsubishi Electric MR-J2S-350B?
Change the servo amplifier if there are faulty parts in the servo amplifier. Alarm (19) occurs if power is switched on after disconnection of all cable but the control circuit power supply cable.
What to do for memory error 2 in Mitsubishi Electric MR-J2S-350B?
To solve memory error 2 on your Mitsubishi Electric Amplifier, change the servo amplifier if there are faulty parts in the servo amplifier. Alarm (15) occurs if power is switched on after disconnection of all cables but the control circuit power supply cables.
How to fix overcurrent in Mitsubishi Electric MR-J2S-350B?
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.
