Mitsubishi Electric FR A802 GF F.A.Q.

How do I perform a factory reset on the Mitsubishi Electric FR A802 GF?

To perform a factory reset on the FR A802 GF, navigate to the parameter settings menu, find the 'All Clear' parameter, and initiate the reset by following the instructions in the user manual. Ensure the motor is stopped and the drive is in a safe state before proceeding.

What is the procedure for troubleshooting overcurrent faults on the FR A802 GF?

Check for mechanical obstructions or excessive load on the motor. Ensure that the motor and drive are properly matched. Verify the wiring and inspect for short circuits. Adjust the acceleration and deceleration times if necessary.

How can I connect the FR A802 GF to a PLC for control?

Use the built-in RS-485 communication interface or an optional communication module such as Ethernet/IP. Configure the drive's communication parameters to match those of the PLC, and ensure the PLC is programmed to send and receive the necessary control signals.

What regular maintenance should be performed on the FR A802 GF?

Regular maintenance includes cleaning the drive's cooling fans and heat sinks to prevent overheating, inspecting electrical connections for tightness and corrosion, and checking for firmware updates. It's important to follow the manufacturer's maintenance schedule for optimal performance.

How do I adjust the acceleration time on the FR A802 GF?

Access the parameter settings and modify the acceleration time parameter to the desired value. This can be done through the drive's keypad or using a computer and the Mitsubishi Electric configuration software.

Why is the FR A802 GF displaying an 'Overvoltage' error and how can I fix it?

An 'Overvoltage' error typically occurs when the DC bus voltage exceeds its threshold. Check the power supply for voltage fluctuations, ensure deceleration times are not too short, and examine the braking resistor for proper operation.

How can I ensure energy savings when using the FR A802 GF?

Utilize the drive's energy-saving functions such as automatic energy optimization and load-based torque control. Regularly review and adjust operational parameters to match the application's needs without excess energy consumption.

Can I operate multiple motors with a single FR A802 GF drive?

Yes, but it requires careful configuration. The drive must be set up to handle the combined load of all motors. Use appropriate output contactors and ensure that the total motor current does not exceed the drive's rated capacity.

What should I do if the FR A802 GF drive does not start the motor?

Verify that all start commands are correctly configured and that the drive is not in a fault state. Check the wiring between the drive and motor, and ensure that the motor's parameters are correctly set in the drive.

How do I update the firmware on the FR A802 GF?

Download the latest firmware from Mitsubishi Electric’s website. Use the appropriate software tool to upload the firmware to the drive via its communication port. Follow the instructions provided with the firmware package carefully to avoid errors.
