Current measurement method

When measuring current, if you open the output side while current is flowing on the input side, high voltage is induced and dielectric breakdown may occur wi... 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 >>

"PS" appears when the STOP key on the operation panel is pressed during external operation. It is considered that someone pressed the key. Dismiss "PS" in on... More Details >>

Inverter 200 V input and 400 V output

We do not have an inverter that directly takes 200 V input and generates 440 V output. Therefore, as you mention, use a 400 V class inverter by boosting the ... More Details >>

Influence by PHS

PHS does not cause the inverter to malfunction.On the contrary, if you use PHS near an inverter or motor, communication over PHS may become noisy or even get... More Details >>
