What does an absolute position erased error mean on Mitsubishi Electric MELSERVO-J4 Amplifier?
An 'absolute position erased' error in your Mitsubishi Electric Amplifier indicates that the absolute position has been erased from either the servo motor encoder or the scale measurement encoder.
What causes an encoder initial communication error 1 in Mitsubishi Electric MELSERVO-J4 Amplifier?
An encoder initial communication error 1 in your Mitsubishi Electric Amplifier may be due to: * Receive data errors 1, 2, or 3. * Transmission data errors 1, 2, or 3. * Process errors 1, 2, 3, 4, 5, or 6.
What does an encoder initial communication error 2 mean on Mitsubishi Electric MELSERVO-J4 Amplifier?
An encoder initial communication error 2 on your Mitsubishi Electric Amplifier indicates an encoder malfunction or a load-side encoder malfunction.
