What to do if Mitsubishi Electric MR-J2S-A Amplifier rotation ripples are large at low speed?
If you observe large rotation ripples (speed fluctuations) at low speed with your Mitsubishi Electric Amplifier, it is likely due to a gain adjustment fault. To resolve this, make gain adjustments by increasing the auto-tuning response level and repeating acceleration and deceleration several times to complete auto-tuning.
What to do if Mitsubishi Electric MR-J2S-A servo motor does not rotate?
If the Mitsubishi Electric Amplifier servo motor does not rotate, it could be due to wiring mistakes. If using open collector pulse train input, ensure 24VDC power is supplied to OPC and that LSP and LSN are on. Also, check that pulses are being input.
Why is the Mitsubishi Electric MR-J2S-A Amplifier servo motor shaft free?
The servo motor shaft might be free because servo-on (SON) is not input due to a wiring mistake, or because 24VDC power is not supplied to COM. Check the display to see if the servo amplifier is ready to operate and check the external I/O signal indication to see if the servo-on (SON) is ON.
What to do if Mitsubishi Electric MR-J2S-A Amplifier position shift occurs?
If position shift occurs with your Mitsubishi Electric Amplifier, it could be due to pulse counting errors caused by noise. Confirm the cumulative command pulses, cumulative feedback pulses, and the actual servo motor position.
Why is the Mitsubishi Electric MR-J2S-A Amplifier servo motor shaft not servo-locked?
The servo motor shaft may not be servo-locked because servo-on (SON) is not input (possibly due to a wiring mistake), or 24VDC power is not supplied to COM. Check the wiring and ensure 24VDC is supplied.
What to do if Mitsubishi Electric MR-J2S-A LED is not lit or flickers?
If the LED on your Mitsubishi Electric Amplifier is not lit or flickers, check the power supply. It could be due to a power supply voltage fault or the servo amplifier being faulty. Also, check for shorts in the power supply of CN1 cabling, CN3 cabling, or encoder cabling. Repair the cabling or replace the encoder if faulty.
What causes Overload 1 on a Mitsubishi Electric MR-J2S-A Amplifier?
Overload 1 can occur if the servo amplifier is used in excess of its continuous output current. To resolve this, reduce the load, review the operation pattern, or use a servo motor that provides a larger output.
