Mitsubishi Electric FR A700 F.A.Q.

How do I perform a factory reset on the Mitsubishi Electric FR A700?

To perform a factory reset on the FR A700, navigate to the parameter settings menu and set parameter 77 to 1. Then, cycle the power to reset the drive to its factory settings.

What is the procedure to connect the FR A700 to a PLC?

To connect the FR A700 to a PLC, use the RS-485 communication interface. Configure the communication parameters such as the baud rate and station number in the drive's settings to match those of the PLC.

How can I troubleshoot an overcurrent fault on the FR A700?

Check for any short circuits or ground faults in the motor and its wiring. Ensure that the motor is not overloaded and verify that the drive's settings match the motor's specifications.

What maintenance is required for the FR A700 inverter?

Regularly inspect the inverter for dust and dirt buildup, especially on the cooling fins and vents. Perform periodic checks on the electrical connections to ensure they are secure. Replace the cooling fan every 3 to 5 years depending on usage.

How do I set up a V/F control mode on the FR A700?

Access the parameter settings and set parameter 80 (Control mode) to 0 for V/F control. Adjust the V/F pattern parameters (parameters 2 and 3) to match the motor characteristics.

What steps should I follow to extend the life of my FR A700 inverter?

Ensure proper ventilation around the inverter to prevent overheating. Regularly clean the device, maintain stable input power, and monitor the load to avoid overloading. Implement preventive maintenance by checking for any unusual noises or vibrations.

Can I use the FR A700 with a single-phase input?

Yes, the FR A700 can be used with a single-phase input by derating the inverter. Ensure that the input voltage and current ratings are compatible with the drive's specifications.

How can I minimize harmonic distortion when using the FR A700?

Install a line reactor or an active filter to reduce harmonic distortion. Ensure the inverter's parameters are properly set to minimize harmonics, and consider using a higher-rated inverter if necessary.

What is the function of the PID control in the FR A700, and how can I set it up?

The PID control function allows for automatic control of process variables. To set it up, configure the PID parameters: set the target value, adjust the proportional, integral, and derivative gains (parameters 96, 97, and 98), and enable the PID function via parameter 90.

How do I update the firmware on the FR A700?

Firmware updates for the FR A700 are typically handled through Mitsubishi Electric's service centers or authorized distributors. Contact them for the latest firmware and instructions on how to perform the update safely.
