Note 1. For
a 400-V Inverter
, if the carrier frequency is set to a value higher than the default setting, the
Inverter overload “OL2” detection value will decrease in consideration of an increase in the
heat that will be generated by the change in the carrier frequency.
Note 2. Default settings vary with the Inverter model.
