What to do if the Mitsubishi Electric FR-E720-0.75K Inverter option unit does not function?
- B
  Brett RileyAug 18, 2025
  If the option unit of your Mitsubishi Electric Inverter isn't working, try these steps: * Ensure the option is correctly fitted. * Reset the inverter. * Perform a complete parameter reset to return to initial values, then power the inverter on again. If you're using a network, check that: * Network cables between nodes are properly connected and terminated. * Network settings are correct using the Profibus-DP Network Configuration Software. * Other nodes aren't showing network errors. * The Profibus-DP master is properly connected and functioning.

What to do if Mitsubishi Electric Inverter shows overcurrent trip during acceleration?
- E
  Elizabeth AndersonAug 20, 2025
  If the Mitsubishi Electric Inverter experiences overcurrent during acceleration, it indicates that overcurrent has occurred. To resolve this, try the following: Set a longer acceleration time. If 'E.OC1' appears at start, disconnect the motor and restart the inverter. If 'E.OC1' persists, the inverter may be faulty and you should contact your sales representative. Check the wiring for output short circuit and ground fault. When the rated motor frequency is 50Hz, set the Pr. 3 Base frequency to 50Hz. Lower the stall prevention operation level. Activate the stall prevention operation and the fast-response current limit operation (Pr.156). For operations with frequent regenerative driving, set the base voltage in Pr. 19 Base frequency voltage.

- W
  William RamosAug 23, 2025
  If the Mitsubishi Electric Inverter's regenerative brake duty reaches 85% of the Pr. 70 Special regenerative brake duty setting or higher, set a longer deceleration time and check the settings of Pr.30 Regenerative function selection and Pr. 70 Special regenerative brake duty.

What causes the electronic thermal relay function pre-alarm on Mitsubishi Electric FR-E720-0.75K, and how to resolve it?
- H
  harrisjenniferAug 26, 2025
  If the cumulative value of the electronic thermal O/L relay has reached 85% of the Pr. 9 Electronic thermal O/L relay setting or higher on your Mitsubishi Electric Inverter, reduce the load and frequency of operation. Also, set an appropriate value in Pr. 9 Electronic thermal O/L relay.

What causes output phase loss in Mitsubishi Electric Inverter?
- C
  Christopher GonzalezAug 28, 2025
  If the Mitsubishi Electric Inverter detects a loss in one of the three output phases (U, V, W) during operation, ensure the cables are properly wired. If the motor capacity is smaller than the inverter capacity, choose matching inverter and motor capacities.

What to do for write disable error on Mitsubishi Electric Inverter?
- G
  Gary SimmonsSep 2, 2025
  If the Mitsubishi Electric Inverter is showing a write disable error, check the setting of Pr. 77 Parameter write selection, the settings of Pr. 31 to Pr. 36 (frequency jump), and the connection of PU and the inverter.

How to clear maintenance signal output on Mitsubishi Electric Inverter?
- M
  Mark SchultzSep 7, 2025
  If the Mitsubishi Electric Inverter outputs a maintenance signal, and the cumulative energization time has exceeded the maintenance output timer set value, setting '0' in Pr. 503 Maintenance timer erases the signal.

What causes undervoltage on Mitsubishi Electric FR-E720-0.75K?
- G
  Gregory WashingtonSep 9, 2025
  If the Mitsubishi Electric Inverter detects undervoltage, it means the voltage at the main circuit power has been lowered. Investigate the devices on the power supply line, including the power supply itself.
