* 1. The setting range and the factory setting of the Inverter will differ depending on its capacity and control method. (The value
for the 200 V class 0.4 kW Inverter in open loop vector control mode is given.) (See page - 35.)
* 2. For a 400 V Inverter, if the carrier frequency is set to a value higher than the factory setting, the Inverter overload “OL2” detec-
tion value will decrease.
