Even though the maximum frequency setting is changed using CC-Link, the running frequency is not changed. By writing the set frequency to the remote register... More Details >>

Offline auto tuning

Auto tuning can be performed because the motor is one rank lower than the inverter capacity. More Details >>

Inverter circuit breaker selection

Since the inverter leakage current is in proportion to the switching voltage of the transistor of the main circuit, the leakage current for the 400 V system ... More Details >>

Countermeasure against noise on input side

In general, the line noise filter (FR-BLF) is used against the power supply noise. The AC reactor also works. As other countermeasures:- Use a metal conduit ... More Details >>
