Inverter analog output

Since the inverter has only one voltage output (10 VDC) from terminal AM as the analog monitor, use the FR-EPA or FR-EPE option if you need two channels. The... More Details >>

Can I use a motor of which capacity is larger than the inverter capacity?

Even when the actual load (torque) is half of the motor capacity, the current output from the inverter to the motor is not reduced to the half. Therefore, it... More Details >>

Inverter input current

Since the input current has a distorted waveform and the waveform ratio is low, the total inverter input power factor is very poor depending on the power sup... More Details >>

Offline auto tuning

Leave the setting of Pr.96 as "3". It indicates that auto tuning has been completed and the motor constant has been read. When it is changed unnecessarily, t... More Details >>

Replacement of the SF-JR with the SF-PR

Since the SF-PR is more efficient compared to the SF-JR, the resistance will decrease and the load current will increase. Check the following two points when... More Details >>
