Mitsubishi Electric F800-E, FR-F820, FR-F840 F.A.Q.

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

To perform a factory reset on the F800-E, navigate to the parameter setting mode, locate parameter 'Pr. 77', and set it to '2'. This will reset all parameters to their factory defaults. Ensure to back up any custom settings before performing the reset.

What is the procedure for troubleshooting an overcurrent fault on the FR-F820?

First, check for any mechanical binding or overload conditions in the motor. Inspect the wiring for any shorts or damage. Ensure that the motor's rated current matches the drive settings. If the problem persists, reduce the acceleration and deceleration times or consult the drive manual for further diagnostics.

How can I optimize energy savings using the Mitsubishi FR-F840?

Utilize the built-in energy-saving functions of the FR-F840, such as the automatic energy-saving mode and the optimum excitation control. Regularly maintain the system to ensure efficient performance and adjust the drive parameters to match the load requirements for optimal energy efficiency.

What maintenance should be regularly performed on the FR-F820 to ensure optimal performance?

Regularly inspect the cooling system, including fans and heat sinks, for dust and debris. Check all electrical connections for tightness and signs of wear. Regularly update the firmware if necessary and verify parameter settings. Ensure the environment is within specified temperature and humidity ranges.

How do I configure PID control on the Mitsubishi F800-E?

Enter the parameter setting mode and configure the PID parameters: 'Pr. 128' for proportional gain, 'Pr. 129' for integral time, and 'Pr. 130' for derivative time. Adjust these values to match your system's dynamics, and enable PID control through 'Pr. 127'. Consult the manual for detailed instructions on tuning.

What steps should be taken if the FR-F840 displays a communication error?

Check the communication cable connections and ensure they are secure. Verify that the communication settings match between the drive and the controller. Inspect for any electromagnetic interference and ensure proper grounding. If the error persists, consult the manual for specific error codes and solutions.

How can I extend the lifespan of my Mitsubishi FR-F820 drive?

Ensure proper ventilation around the drive to prevent overheating. Regularly clean and inspect the drive for dust and contaminants. Avoid frequent start/stop cycles and maintain stable environmental conditions. Schedule periodic maintenance checks to identify and rectify issues early.

What are the steps to update the firmware on the Mitsubishi Electric F800-E?

Download the latest firmware from the Mitsubishi Electric website. Connect your PC to the drive using the appropriate interface. Use the Mitsubishi software tool to upload the firmware to the drive, ensuring that the drive is in a safe state before proceeding. Follow the on-screen instructions to complete the update process.

How do I set up a speed control using an external signal on the FR-F840?

Connect the external signal to the designated input terminals on the drive. Adjust the parameter settings: 'Pr. 79' for frequency setting, and 'Pr. 178' for external input selection. Calibrate the input range using 'Pr. 902' and test the setup to ensure accurate speed control.

Why is my FR-F820 not starting the motor even though there are no error codes displayed?

Check that the start command is being received by the drive. Verify that all safety interlocks and emergency stop circuits are closed. Ensure that the motor and drive parameters are correctly configured. Inspect the input power supply for stability and confirm that the run command is active.
