Mitsubishi Electric FR FC F.A.Q.

How do I reset the Mitsubishi Electric FR-FC inverter to factory settings?

To reset the inverter to factory settings, press the 'MODE' button to enter the parameter setting mode, navigate to parameter 79 (Pr.79), and set its value to 1. Press the 'SET' button to confirm. This will reset all parameters to default. Ensure the inverter is stopped before performing this action.

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

First, check the motor and cable connections for any short circuits or disconnections. Verify the load conditions and ensure they are within the inverter's specifications. If the issue persists, check the settings for acceleration and deceleration times and adjust them to prevent sudden load changes.

How can I change the frequency reference source on the FR-FC inverter?

To change the frequency reference source, access parameter 79 (Pr.79) and select the desired input method, such as analog input or digital input. Adjust the parameter setting accordingly to suit your application requirements.

Why is the inverter not starting even though the RUN command is given?

Ensure that all safety interlocks and external wiring connections are properly secured. Check that the RUN command is correctly configured and that there are no active alarms or parameter settings preventing the inverter from starting.

How do I perform regular maintenance on the FR-FC inverter?

Regular maintenance includes cleaning the inverter's cooling fan and heat sink to prevent overheating, inspecting electrical connections for tightness, and checking for any unusual noises or vibrations during operation. Ensure that the environment is free of dust and moisture.

What parameters should I adjust for energy saving?

Consider adjusting parameters related to the motor control method, such as switching to V/F control for less demanding applications. Fine-tune acceleration and deceleration times, and use the energy-saving mode if available. Regularly monitor and adjust based on load conditions.

Can the FR-FC inverter be used with a generator?

Yes, the FR-FC inverter can be used with a generator. However, ensure the generator's capacity is sufficient to handle the inverter's power requirements. Use a power filter to protect the inverter from generator fluctuations, and confirm compatibility with harmonic distortion levels.

How can I monitor the inverter's performance remotely?

Install the appropriate communication option card for your inverter model to enable remote monitoring. Use compatible software or a PLC with a communication protocol like Modbus to interface with the inverter and monitor performance data.

What should I do if the inverter overheats frequently?

Check the installation environment for adequate ventilation and ensure the cooling fan is operational. Clean dust and debris from the heat sink and fan. Verify that the inverter is not overloaded and that its settings are within the specified thermal limits.

How can I extend the lifespan of my Mitsubishi Electric FR-FC inverter?

Regular maintenance, such as cleaning and inspection, is crucial. Operate the inverter within its specified limits and avoid frequent start-stop cycles. Ensure proper cooling and ventilation. Update parameters based on the application needs and use protective devices like surge protectors.
