What to do if Mitsubishi Electric MR-J4W2 shows connector communication error?
- P
  Paul RamosAug 19, 2025
  If the Mitsubishi Electric Amplifier experiences a connector communication error, it might be due to disconnected communication with the servo system controller. To resolve this, switch on the power of the servo system controller. Another cause could be that initialization communication with the servo system controller has not completed. In this case, turn off the disabling control axis switches (SW2-2, 2-3, and 2-4).

What causes memory error 2 (EEP-ROM) in Mitsubishi Electric MR-J4W2 Amplifier?
- O
  obarberSep 6, 2025
  A memory error 2 (EEP-ROM) in the Mitsubishi Electric Amplifier may be caused by an EEP-ROM error at power on or during operation.
B
Brian BurnsSep 7, 2025
What is the cause of control process error in Mitsubishi Electric MR-J4W2?
- S
  Steve HumphreySep 7, 2025
  A control process error in the Mitsubishi Electric Amplifier can be caused by control process errors 1 through 10.
