How to fix large rotation ripples at low speed on Mitsubishi Electric MR-J2S-70CP-S084?
If you notice large rotation ripples (speed fluctuations) at low speed with your Mitsubishi Electric Amplifier, it's likely due to a gain adjustment fault. To resolve this, increase the auto tuning response level and repeat acceleration and deceleration several times to complete auto tuning.
What to do if Mitsubishi Electric Amplifier servo motor shaft oscillates due to large load inertia?
If a large load inertia moment causes the servo motor shaft to oscillate side to side on your Mitsubishi Electric Amplifier, the cause is likely a gain adjustment fault. If the servo motor may be run with safety, repeat acceleration and deceleration several times to complete auto tuning.
Why is Mitsubishi Electric MR-J2S-70CP-S084 servo motor shaft not servo-locked?
If the servo motor shaft of your Mitsubishi Electric Amplifier is not servo-locked, and is free, it could be due to a couple of reasons: 1. Servo-on (RYn0) is not input due to a wiring mistake. Check the display to see if the servo amplifier is ready to operate. 2. 24VDC power is not supplied to COM. Check the external I/O signal indication to see if the servo-on (RYn0) signal is ON.
Why is the LED not lit or flickering on my Mitsubishi Electric MR-J2S-70CP-S084 Amplifier?
The LED on your Mitsubishi Electric Amplifier might not be lit or may flicker due to several potential issues: * A power supply voltage fault. This is not improved if connectors CN1A, CN1B, CN2 and CN3 are disconnected. * A faulty servo amplifier. This is also not improved if connectors CN1A, CN1B, CN2 and CN3 are disconnected. * A shorted power supply of CN1 cabling. This is improved when connectors CN1A and CN1B are disconnected. * A shorted power supply of encoder cabling or a faulty encoder. This is improved when connector CN2 is disconnected. * A shorted power supply of CN3 cabling. This is improved when connector CN3 is disconnected.
