If your Mitsubishi Electric Servo Drives show undervoltage, it could be due to a voltage drop in either the control circuit or the main circuit power. Therefore, check both the control circuit and the main circuit power supplies to resolve this issue.
What to do if Mitsubishi Electric Servo Drives report a main circuit error?
If your Mitsubishi Electric Servo Drives encounter a main circuit error, it indicates a ground fault detected either by the hardware detection circuit or the software detection function. In both cases, you should check the main circuit for faults.
What causes encoder initial communication error 1 on Mitsubishi Electric MR-J4-700B(-RJ)?
If your Mitsubishi Electric Servo Drives are showing an encoder initial communication error, it could be due to several reasons: * Receive data error. * Encoder malfunction. * Transmission data error. * Incompatible encoder. * Process error. To address this, check the encoder connection, replace the malfunctioning encoder, check transmission data for integrity, ensure encoder compatibility and check process configuration.
How to fix switch setting error on Mitsubishi Electric Servo Drives?
If your Mitsubishi Electric Servo Drives experience a switch setting error, it may be due to an incorrect axis number or station number setting, or a disabling control axis setting error. To resolve this, verify the axis number and station number settings and ensure the control axis is enabled.
What causes initial magnetic pole detection error on Mitsubishi Electric MR-J4-700B(-RJ)?
If your Mitsubishi Electric Servo Drives are showing an initial magnetic pole detection error, it could be due to several reasons: * Abnormal termination. * Time out error. * Limit switch error. * Estimated error. * Position deviation error. * Speed deviation error. * Current error. To address this, investigate magnetic pole settings, ensure appropriate timing configurations, check limit switches for proper operation, review estimated parameter settings, re-evaluate position deviation parameters, review speed deviation settings and check current settings and limits.
What does memory error 2 (EEP-ROM) mean on Mitsubishi Electric Servo Drives?
If your Mitsubishi Electric Servo Drives display 'Memory error 2 (EEP-ROM)', it can be due to an EEP-ROM error at power on, an EEP-ROM error during operation or a home position information read error. Check the EEP-ROM connection, operational integrity of EEP-ROM, and verify home position information.
What to do if Mitsubishi Electric MR-J4-700B(-RJ) report memory error 1 (RAM)?
If your Mitsubishi Electric Servo Drives show a memory error 1 (RAM), it indicates a RAM error. Replace the RAM module.
What does clock error mean on Mitsubishi Electric MR-J4-700B(-RJ) Servo Drives?
If your Mitsubishi Electric Servo Drives have a clock error, it indicates an issue with the clock settings. Check the clock settings.
What causes linear encoder error 2 on Mitsubishi Electric Servo Drives?
If your Mitsubishi Electric Servo Drives are showing a linear encoder error, this is due to an environmental error. Assess and rectify environmental conditions.
How to resolve network module initialization error on Mitsubishi Electric MR-J4-700B(-RJ)?
If your Mitsubishi Electric Servo Drives have a network module initialization error, it could be caused by the network module being undetected or due to initialization errors. Check the network module connections and check the network module for faults.
