Countermeasures when input power supply is turned off upon equipment fault

1. When the inverter power supply is turned OFF, the inverter is disconnected from the CC-Link network. However, since the CC-Link master station has the aut... More Details >>

Installing reactor for suppressing harmonics

You can connect multiple inverters to a single reactor. In this case, the load seems to be light from the reactor unless all of the inverters are rotating an... More Details >>

Inverter signal input speed

There is a 10 ms delay after the inverter recognizes the start command (STF OR STR) before it starts decelerating. The delay is 10 ms. A delay of 100 ms is i... More Details >>

Inverter with one-rank higher capacity
