How to reset Mitsubishi Electric FR-A700?
You can reset the Mitsubishi Electric Inverter by: * Pressing the reset button on the operation panel. * Switching the power off and then on again. * Turning on the reset signal (RES) for more than 0.1s. Note that resetting the inverter clears the internal thermal integrated value of the electronic thermal relay function and the number of retries.
How to reset Mitsubishi Electric Inverter after protective function activation?
When the protective function of your Mitsubishi Electric Inverter is activated, first take the required corrective action. Then, reset the inverter and resume operation.
What happens when Mitsubishi Electric FR-A700 experiences a fault?
When a fault occurs in your Mitsubishi Electric Inverter, the inverter trips and outputs a fault signal.
Why Mitsubishi Electric FR-A700 Inverter motor does not run at correct speed?
If the speed command from the command device is incorrect or compounded with noise, ensure that a correct speed command is being sent from the device. If the speed command value doesn't match the value recognized by the Mitsubishi Electric Inverter, readjust the speed command bias/gain using Pr. 125, Pr. 126, C2 to C7 and C12 to C15. Also, verify the setting of Pr. 369 Number of encoder pulses if you are using vector control.
How to troubleshoot motor not rotating in Mitsubishi Electric FR-A700?
If the motor does not rotate under vector control, begin by checking the motor wiring. Then, select V/F control (set "9999" in Pr. 80 or Pr. 81) to check the motor's rotation direction. Verify the encoder specifications and wiring, ensuring that FWD is displayed when running the motor counter-clockwise. Confirm that the Pr. 369 Number of encoder pulses setting matches the encoder being used. Finally, check the encoder's power specifications (5V/12V/15V/24V) and input the external power supply.
What to do if speed does not rise to the speed command in Mitsubishi Electric FR-A700 Inverter?
If the speed of your Mitsubishi Electric Inverter does not rise to the speed command, it might be due to insufficient torque. In this case, increase the torque limit value. Alternatively, check if only P (proportional) control is selected; if so, switch to PI control.
How to fix if Mitsubishi Electric FR-A700 Inverter speed does not rise to the speed command?
If the speed of your Mitsubishi Electric Inverter does not rise to the speed command, it could be due to insufficient torque, causing the torque limit to activate. To fix this, increase the torque limit value. Alternatively, only P (proportional) control might be selected. In this case, switch to PI control.
Why Mitsubishi Electric FR-A700 does not hold alarm output?
When the magnetic contactor (MC) on the input side of the Mitsubishi Electric Inverter is opened upon activation of the protective function, the inverter's control power is lost, and the alarm output will not be held.
What to do with warnings on Mitsubishi Electric FR-A700?
Even when a warning is displayed, the Mitsubishi Electric Inverter won't trip. However, you should take appropriate measures to prevent a major fault from occurring.
How to turn on the reset signal on Mitsubishi Electric Inverter?
Turn on the reset signal (RES) for more than 0.1s on your Mitsubishi Electric Inverter.
