Mitsubishi Electric FR D700 F.A.Q.

How do I reset the Mitsubishi Electric FR D700 inverter to factory settings?

To reset the FR D700 inverter to factory settings, switch off the power, press and hold both the PU and STOP keys, then power on the inverter while keeping the buttons pressed until the display reads 'InIt'.

What is the procedure to perform a parameter initialization on the FR D700?

To initialize parameters, set Pr. 77 to '1' and then press the STOP/RESET key. This will reset all parameters to their default values.

How can I troubleshoot an overvoltage fault on the FR D700?

Overvoltage faults can occur due to excessive input voltage or regeneration during deceleration. Check the input voltage and consider using a braking resistor to handle regenerative energy.

What is the recommended maintenance schedule for the FR D700 inverter?

Regular maintenance should include inspecting the cooling fan and heat sinks every 6 months, checking connections and tightening screws annually, and replacing the cooling fan every 3 to 5 years.

How do I connect an external frequency setting device to the FR D700?

Connect the external frequency setting device to the analog input terminals (2-5V, 4-20mA) and configure parameters Pr. 73 and Pr. 74 according to the input type.

Can the FR D700 inverter be used with a single-phase power supply?

Yes, the FR D700 can operate on a single-phase power supply by using models specifically designed for single-phase input. Refer to the manual for compatible models.

How do I set up the FR D700 for PID control operation?

To set up PID control, enable the PID function by setting Pr. 128 to '1', and configure the relevant PID parameters such as Pr. 129 to Pr. 134 for tuning.

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

E.OC1 indicates an overcurrent during acceleration. Check for short circuits in the motor wiring, verify motor parameters, and ensure the acceleration time is sufficient.

How can I adjust the acceleration and deceleration times on the FR D700?

Adjust the acceleration time using Pr. 7 and the deceleration time using Pr. 8. Increase these values to lengthen the time or decrease them to shorten it.

Is it possible to control the FR D700 remotely via a PLC?

Yes, the FR D700 can be controlled remotely using a PLC by interfacing through the RS-485 communication port and configuring the necessary communication parameters.
