Speed change due to power supply voltage fluctuation

1. The output frequency satisfies the "control specification/frequency precision" even when the power supply voltage changes, but the output voltage cannot r... 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 >>

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 >>
