Why does the Mitsubishi Electric Controller servo motor not rotate?
If the Mitsubishi Electric Controller's servo motor does not rotate, check the cumulative command pulses, as there might be a wiring mistake. Also, consider that no pulses might be input.
Why is the LED not lit or flickering on my Mitsubishi Electric MR-E-20A?
If the LED on your Mitsubishi Electric Controller is not lit or flickers, it could be due to several reasons: a power supply voltage fault, a faulty servo amplifier, a shorted power supply of CNP1 cabling, a shorted power supply of encoder cabling, a faulty encoder, or a shorted power supply of CN3 cabling.
What to do if the Mitsubishi Electric MR-E-20A Controller servo motor shaft is not servo-locked?
If the Mitsubishi Electric Controller's servo motor shaft is not servo-locked (is free), first, check the display to see if the servo amplifier is ready to operate. This issue might be due to the servo-on signal not being input, potentially caused by a wiring mistake. Also, verify if 24VDC power is supplied to COM. You can check the external I/O signal indication to see if the servo-on (SON) signal is ON.
Why is the Mitsubishi Electric MR-E-20A Controller servo motor running in reverse?
If the Mitsubishi Electric Controller's servo motor runs in the reverse direction, it could be due to a mistake in the wiring to the controller or a mistake in the setting of parameter No. 54.
