Mitsubishi Electric FR F800 F.A.Q.

How do I perform a factory reset on the Mitsubishi Electric FR F800?

To perform a factory reset on the FR F800, navigate to the parameter settings and set parameter 79 (Pr.79) to the value of 1. Then, cycle the power to the inverter. This will reset all settings to factory defaults.

What are the steps to troubleshoot an overcurrent fault on the FR F800?

First, check the motor and wiring for any short circuits or grounding issues. Verify the motor's specifications match the inverter settings. Reduce the load or acceleration time if needed. Consult the manual for specific troubleshooting codes related to overcurrent conditions.

How can I set up the FR F800 for energy-saving operations?

To enable energy-saving operations, adjust parameter 60 (Pr.60) to activate the energy saving mode. You can further optimize by adjusting the voltage and frequency settings to match the motor's requirements and load conditions.

What maintenance procedures should be followed for the FR F800?

Regular maintenance should include cleaning the heat sink and cooling fans, checking electrical connections for tightness, and inspecting for any signs of wear or damage. Ensure that the ambient temperature and ventilation meet the inverter's requirements.

How do I update the firmware on the FR F800 inverter?

To update the firmware, download the latest version from the Mitsubishi Electric support website. Follow the instructions provided with the firmware package, typically involving connecting a compatible interface to the inverter and executing the update through the provided software.

What should I do if the FR F800 display shows a communication error?

Check the communication cable connections and ensure they are secure. Verify that the communication settings on the inverter match those of the connected device. Consult the manual for specific error codes and recommended actions.

How can I configure the FR F800 to operate with a PLC?

First, ensure that the inverter's communication settings are compatible with the PLC. Set the appropriate parameters for communication protocol (e.g., Modbus, Ethernet). Refer to both the inverter and PLC manuals for detailed configuration steps.

Can the FR F800 be used in a multi-motor setup?

Yes, the FR F800 can control multiple motors in a group operation. Proper configuration of parameters related to motor control and protection is required. Consult the user manual for parameter settings specific to multi-motor applications.

What is the recommended procedure for replacing the cooling fan in the FR F800?

Turn off the power and wait for the inverter to discharge completely. Remove the cover to access the cooling fan. Disconnect the fan's power and remove mounting screws. Replace with a new fan, secure it, and reconnect power before replacing the cover.

How do I adjust the acceleration and deceleration times on the FR F800?

Adjust the acceleration time by setting parameter 7 (Pr.7) and the deceleration time by setting parameter 8 (Pr.8) to the desired values. These parameters control the ramp-up and ramp-down times of the motor speed.
