If the main circuit device overheats, it could be due to a faulty servo amplifier, in which case you should change the servo amplifier. It could also be that the power supply was turned on and off continuously by overloaded status, so the drive method is reviewed.
How to fix large rotation ripples at low speed on Mitsubishi Electric Controller?
If you observe large rotation ripples (speed fluctuations) at low speed on your Mitsubishi Electric Controller, make gain adjustment in the following procedure: 1. Increase the auto tuning response level. 2. Repeat acceleration and deceleration several times to complete auto tuning.
Why current is higher than permissible current of Mitsubishi Electric EZMOTION MR-E Super MR-E-70A-QW003 servo amplifier?
If the current is higher than the permissible current of the servo amplifier, it could be due to several reasons: * A short circuit in servo amplifier output phases U, V and W: correct the wiring. * A faulty transistor (IPM) of the servo amplifier: change the servo amplifier. * A ground fault occurred in servo amplifier output phases U, V and W: correct the wiring. * External noise caused the overcurrent detection circuit to misoperate: take noise suppression measures.
How to fix communication error between Mitsubishi Electric EZMOTION MR-E Super MR-E-70A-QW003 Controller encoder and servo amplifier?
If a communication error occurred between the encoder and servo amplifier, check if the encoder connector (CN2) is disconnected and connect it correctly. Other possible causes are encoder fault, in which case you should change the servo motor or encoder cable faulty (Wire breakage or shorted), so you should repair or change cable.
Why Mitsubishi Electric EZMOTION MR-E Super MR-E-70A-QW003 Controller servo motor run in reverse direction?
The servo motor may run in the reverse direction due to a mistake in wiring to the controller or a mistake in setting of parameter No.54.
What to do if incorrect combination of servo amplifier and servo motor on Mitsubishi Electric Controller?
If there is an incorrect combination of servo amplifier and servo motor, use correct combination.
What causes RAM, memory fault on Mitsubishi Electric EZMOTION MR-E Super MR-E-70A-QW003?
If there is a RAM or memory fault, it is due to faulty parts in the servo amplifier, so change the servo amplifier.
What to do if set value is 0 on Mitsubishi Electric EZMOTION MR-E Super MR-E-70A-QW003?
If the set value is 0, check the internal speed commands 1 to 7 (parameters No.8 to 10 72 to 75).
What to do if parameter setting is wrong on Mitsubishi Electric EZMOTION MR-E Super MR-E-70A-QW003 Controller?
If the parameter setting is wrong, it may be due to a servo amplifier fault that caused the parameter setting to be rewritten, in which case you should change the servo amplifier. It could also be that a regenerative option or servo motor not used with servo amplifier was selected in parameter No.0, so set parameter No.0 correctly.
Why Mitsubishi Electric EZMOTION MR-E Super MR-E-70A-QW003 Controller converter bus voltage exceeded 400VDC?
If the converter bus voltage exceeded 400VDC, it may be due to: * Regenerative option is not used: Use the regenerative option. * Though the regenerative option is used, the parameter No.0 setting is '0 (not used)': Make correct setting. * Lead of built-in regenerative resistor or regenerative option is open or disconnected: Change the lead. * Regenerative transistor faulty: Change the servo amplifier.
