FR-BMF

The inverter may be broken due to the temperature rise of the internal parts. More Details >>

FR-HC2

Three phases are measured with the CT. The accuracy is ±10 % which is same as the inverter output current. More Details >>

Torque control

Torque control cannot be performed with the FR-E700 series. It is available with the FR-A700 and FR-V500 series. More Details >>

Is the number of writing times of the parameter memory limited?

1. The limit of the parameter writing is 100,000 times. 2. Parameter error occurs. Since the data in the ROM may be broken, the inverter may become unavailab... More Details >>
