Notes when inverter capacity is larger than motor capacity

When using one-rank-higher inverter, as you mention, you need to care about the setting of the electronic thermal O/L relay.Setting the electronic thermal O/... More Details >>

Analog output

The FM output is 0 to 8 VDC pulse. More Details >>

Output voltage measurement

The inverter's output voltage is controlled by switching DC voltage and has a pulse voltage waveform.(It is not a clean sine wave.)Therefore, it cannot be me... More Details >>
