Mitsubishi FR-F500 FR-F520-0.75K Inverter F.A.Q.

How do I perform a factory reset on the Mitsubishi FR-F500 FR-F520-0.75K Inverter?

To perform a factory reset, enter the parameter setting mode, navigate to parameter 'Pr. 77' and set its value to '9999'. This will reset the inverter to its default settings. Ensure the inverter is stopped before performing the reset.

What is the procedure for troubleshooting a motor that does not start when using the FR-F520-0.75K inverter?

First, check the input power supply and ensure it's within the specified range. Verify all wiring connections are secure. Check for any error codes displayed on the inverter and refer to the manual for specific troubleshooting steps related to those codes.

How can I adjust the acceleration time on my Mitsubishi FR-F520-0.75K inverter?

To adjust the acceleration time, access parameter 'Pr. 7' and input the desired time in seconds. This setting determines how quickly the motor reaches its set speed from a standstill.

What maintenance should be regularly performed on the FR-F520-0.75K inverter?

Regular maintenance includes checking and tightening electrical connections, cleaning the cooling fan and heat sink, inspecting for dust and debris, and ensuring proper ventilation. Conduct these checks every 6 months.

How do I configure the FR-F520-0.75K inverter to display output frequency?

To display the output frequency, set parameter 'Pr. 52' to '1'. This will configure the display to show the frequency instead of other operational metrics.

What should I do if the inverter displays an overcurrent fault?

Check the motor and load for blockages or mechanical issues causing high current draw. Verify cable insulation and connections. Reduce the load or adjust the acceleration time if necessary. If the problem persists, inspect the inverter settings and parameters.

How can I extend the life of my Mitsubishi FR-F520-0.75K inverter?

Ensure proper cooling by keeping the heat sink and fan clean, avoid overloading the inverter, regularly check and maintain electrical connections, and operate the inverter within its specified limits.

Is it possible to operate multiple motors with a single FR-F520-0.75K inverter?

Yes, it is possible to operate multiple motors with a single inverter, but ensure the combined load does not exceed the inverter's capacity. Use appropriate protection and control circuitry for each motor.

How do I set up the inverter for remote operation?

To set up for remote operation, configure the control terminals for external control by setting parameters 'Pr. 79' and 'Pr. 178' appropriately. This allows the inverter to be controlled via external devices or switches.

What are the common error codes for the FR-F520-0.75K inverter and their meanings?

Common error codes include E.OC1 (overcurrent during acceleration), E.OC2 (overcurrent during deceleration), E.OC3 (overcurrent at constant speed), and E.OL (overload). Consult the manual for detailed troubleshooting steps for each code.
