To Next PageTo Next PageWhy input pulse frequency of Mitsubishi Electric EZMOTION MR-E Super MR-E-70A-QW003 Controller command pulse is too high?
If the input pulse frequency of the command pulse is too high, it could be because the pulse frequency of the command pulse is too high, so change the command pulse frequency to a proper value. It could also be that noise entered command pulses, so take action against noise.
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 main circuit device overheat?
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 communication error between Mitsubishi Electric EZMOTION MR-E Super MR-E-70A-QW003 servo amplifier and computer?
If a communication error occurred between the servo amplifier and communication device (e.g. personal computer), it could be due to a communication cable fault (Open cable or short circuit), so repair or change the cable. It could also be that the communication device (e.g. personal computer) is faulty, so change the communication device (e.g. personal computer).
What causes excessive regenerative warning on Mitsubishi Electric EZMOTION MR-E Super MR-E-70A-QW003?
If there is an excessive regenerative warning, it means the regenerative power increased to 85 or more of permissible regenerative power of built-in regenerative resistor or regenerative option. To solve this, you can: 1. Reduce frequency of positioning. 2. Change regenerative option for the one with larger capacity. 3. Reduce load.
Why Mitsubishi Electric Controller servo motor shaft is not servo-locked?
If the servo motor shaft is not servo-locked (is free), 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) signal is ON, as it could be because the servo-on signal is not input (wiring mistake) or 24VDC power is not supplied to COM.
