Mitsubishi FR-AL Inverter F.A.Q.

How do I perform a factory reset on the Mitsubishi FR-AL Inverter?

To perform a factory reset, access the inverter's parameter settings and set parameter 77 (Initialization) to '1'. This will reset all parameters to factory defaults. Ensure the inverter is stopped before performing this operation.

What should I do if the Mitsubishi FR-AL Inverter displays an overcurrent fault?

Check the motor connections for any short circuits or loose connections. Verify that the motor is not overloaded and that the inverter is correctly configured for the motor's ratings. Reset the inverter after resolving the issue.

How can I adjust the speed of a motor using the Mitsubishi FR-AL Inverter?

You can adjust the motor speed by changing the frequency setting. Access the frequency parameter and modify it to the desired value either through the keypad, potentiometer, or external control signals.

Why is the Mitsubishi FR-AL Inverter not starting the motor?

Ensure that the start command is being received by the inverter. Check wiring connections, verify that the run command is active, and confirm that there are no active fault conditions preventing operation.

How often should I perform maintenance on the Mitsubishi FR-AL Inverter?

Regular maintenance should be performed every 6 to 12 months, including checking for dust accumulation, tightening electrical connections, and inspecting for any signs of wear or damage.

What is the procedure for changing the control mode on the Mitsubishi FR-AL Inverter?

Access the parameter settings and change the control mode parameter to the desired mode (e.g., V/F Control, Vector Control). Ensure the motor is stopped before making changes.

How do I troubleshoot a communication error on the Mitsubishi FR-AL Inverter?

Check all communication cables and connections for proper installation. Verify the communication settings, such as baud rate and protocol, match between the inverter and the controlling device.

Can I use the Mitsubishi FR-AL Inverter with a single-phase power supply?

Yes, the FR-AL Inverter can be configured to operate with a single-phase power supply. Consult the inverter manual for specific instructions on wiring and parameter settings for single-phase operation.

How can I extend the lifespan of my Mitsubishi FR-AL Inverter?

To extend the lifespan, ensure proper ventilation, avoid exposure to excessive heat and moisture, perform regular maintenance, and operate the inverter within its specified limits.

What steps should I take if the Mitsubishi FR-AL Inverter overheats?
