Note 1. The setting range and the default of the Inverter will differ depending on its capacity and con-
trol mode. (The value for the 200-V class 0.4 kW Inverter in open loop vector control mode is
given above.)
Note 2. 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.
