Mitsubishi Electric FR F700PJ F.A.Q.

How do I perform a factory reset on the Mitsubishi Electric FR F700PJ?

To perform a factory reset on the FR F700PJ, navigate to parameter 79 (All Parameter Clear) and set it to '1'. This will reset all parameters to factory defaults. Ensure you backup critical settings before performing this operation.

What is the procedure to troubleshoot an overvoltage fault in the FR F700PJ?

Check the power supply voltage to ensure it is within the rated range. Verify that the deceleration time is set appropriately to prevent regenerative voltage spikes. If necessary, install a braking resistor or regenerative braking unit.

How can I integrate the FR F700PJ with a PLC system for automation control?

To integrate with a PLC, use the built-in RS485 communication interface for Modbus RTU protocol. Configure communication parameters (Pr.117 to Pr.124) and ensure the PLC is set to match these settings for seamless integration.

What maintenance practices are recommended for the FR F700PJ inverter?

Regularly clean the cooling fins and ensure adequate ventilation to prevent overheating. Inspect electrical connections for signs of wear or corrosion and ensure they are secure. Perform visual checks for any physical damage or dust accumulation.

How do I adjust the acceleration and deceleration times on the FR F700PJ?

Adjust the acceleration time using parameter Pr.7 and the deceleration time using parameter Pr.8. Set these values according to your application requirements to ensure smooth motor operation.

What should I do if the FR F700PJ inverter displays an E.OC1 error?

An E.OC1 error indicates an overcurrent during acceleration. Check for short circuits in the motor cables, verify proper motor parameters (Pr.71 to Pr.75), and ensure the motor is not overloaded. Consider increasing the acceleration time if necessary.

Can the FR F700PJ be used with single-phase motors?

The FR F700PJ is designed for three-phase motors. Using it with single-phase motors is not recommended, as it may lead to improper operation or damage to the inverter and motor.

How do I configure the FR F700PJ for PID control?

Enable PID control by setting parameter Pr.128 to '1'. Configure the PID setpoint and feedback settings (Pr.129 to Pr.135) based on your application requirements. Fine-tune the PID parameters for optimal performance.

What is the recommended procedure to update the firmware on the FR F700PJ?

Firmware updates should be performed by authorized personnel. Contact Mitsubishi Electric support for the latest firmware and follow their instructions for updating, ensuring that the inverter is not powered during the process.

How can I reduce the electromagnetic interference (EMI) from the FR F700PJ?

Install an EMI filter on the power input side of the inverter. Use shielded cables for motor connections and ensure proper grounding. Additionally, avoid running sensitive signal cables parallel to the inverter's power cables.
