PLC function

When Pr.414 is set to "1" and Pr.388 is set to "0", the PLC function is not enabled unless both the SQ signal from communication and the SQ signal from the e... More Details >>

Simple magnetic flux vector control

The simple magnetic flux vector control is unavailable for the FR-F800. The advanced magnetic flux vector control is higher-level function of the simple magn... More Details >>

Built-in PLC function

The error indicates that the parameter setting of the PLC function is not set. It is considered that the PC parameter is not checked when the PC parameter an... More Details >>

Operation at external operation/stop

It is recommended to turn OFF the start signals (STF and STR) when stopping the inverter.In this case, it is not probable that the motor rotates due to a cal... More Details >>

Fault contact when connecting separate power supply for each control circuit

Since the inverter's fault contact is an NC contact, it does not open unless a fault occurs.Therefore, when the control power supply (and main circuit power ... More Details >>

Current increase at motor stop

If the current increases when the motor stops under V/F control (at low speed under a light load), the motor is considered to be in the overexcitation state.... More Details >>

Fault code

Regenerative overvoltage protection (E.OVT).This error occurs when the regenerative power returns from the motor to the inverter (for example, during deceler... More Details >>

Built-in potentiometer and current input switching control

For setting the frequency, you cannot switch between the operation panel potentiometer and current input from an external source.To switch between the extern... More Details >>

Input power supply circuit breaker

When using a motor circuit breaker, the rated current of the motor circuit breaker to use must be equal to or higher than the rated current of the circuit br... More Details >>
