Operation by single-phase power supply

Similarly to the FR-A220, single-phase power supply operation is possible by reducing the inverter's output current.Ensure that the output current is smaller... More Details >>

Long motor wiring

When you use a long wire between the inverter and motor, pay attention to the following: 1. Since the voltage supplied to the motor terminal is reduced due t... More Details >>

Load current limit of inverter

You can input current from the terminal AM of the inverter to the programmable controller (for A/D conversion) and control the speed with the software of the... More Details >>

Functions available when using inverter on CC-Link

You can use the regular terminal block wire functions during CC-Link operation. 　Set Pr.338 (Operation command source) and Pr.339 (Speed command source) to e... More Details >>

Reset command during operation

The reset signal does not damage the inverter.It seems that the inverter went faulty due to other reasons.Mitsubishi Electric FA Center can inspect the inver... More Details >>

Terminal FM

Since the terminal FM is designed with 8 V peak pulse voltage output, it cannot output 10 V.Since the terminal AM is an analog output of 0 V to 10 V, use thi... More Details >>

Motor heat generation at low-speed operation

When using the FR-A540-3.7K in Advanced magnetic flux vector control, operating the motor continuously under the 100% torque at up to 3 Hz does not cause a h... More Details >>

Coasting

When the inverter output shutoff signal MRS is turned on, the output is shut off immediately without regard to setting of Pr.250. More Details >>
