What causes overload 2 in Mitsubishi Electric MR-J2S-700B Amplifier and how to fix it?
- A
  Amanda HendrixAug 25, 2025
  To troubleshoot an overload (Overload 2) in your Mitsubishi Electric Amplifier: * Review the operation pattern and install limit switches if the machine struck something. * Ensure correct connection of the servo motor, matching the servo amplifier's output terminals U, V, W to the servo motor's input terminals U, V, W. * If the servo system is unstable and hunting, repeat acceleration/deceleration to execute auto-tuning, change the auto-tuning response setting, or set auto-tuning to OFF and make gain adjustment manually. * If the encoder is faulty (when the servo motor shaft is rotated with the servo off, the cumulative feedback pulses do not vary in proportion to the rotary angle of the shaft but the indication skips or returns midway), replace the servo motor.

How to troubleshoot main circuit error on Mitsubishi Electric Amplifier?
- E
  Erica ReedAug 26, 2025
  To resolve a main circuit error in your Mitsubishi Electric Amplifier: * Ensure that the power input wires and servo motor output wires are correctly connected at the main circuit terminal block (TE1). * Change the cable if the sheathes of servo motor power cables deteriorated, resulting in a ground fault. * Replace the servo amplifier if the main circuit of the servo amplifier failed. Alarm (24) occurs if the servo is switched on after disconnecting the U, V, W power cables from the servo amplifier.

- H
  harristylerAug 29, 2025
  To troubleshoot a board error on your Mitsubishi Electric Amplifier: * Change the servo amplifier if there are faulty parts in the servo amplifier. Alarm (17) occurs if power is switched on after disconnection of all cable but the control circuit power supply cable. * Correctly connect the output terminals U, V, W of the servo amplifier and the input terminals U, V, W of the servo motor if they are not connected.

How to solve parameter error on Mitsubishi Electric Amplifier?
- D
  David FisherAug 30, 2025
  To address a parameter error in your Mitsubishi Electric Amplifier: * Change the servo amplifier if a servo amplifier fault caused the parameter setting to be rewritten. * Change the parameter value to within the setting range if there is a parameter whose value was set outside the setting range by the controller. * Change the servo amplifier if the number of write times to EEP- ROM exceeded 100,000 due to parameter write, etc.
