E2: Motor Setup
* 1. The default depends on the MxC capacity. The value for a 200 V class MxC of 5.5 kW is given.
* 2. The setting range is from 10% to 200% of the MxC rated output current. The value for a 200 V class MxC for 5.5 kW is given. The upper limit of the Motor No-
Load Current (E2-03) must be less than the Motor Rated Current (E2-01).
* 3. The setting range depends on the MxC capacity. The value for a 200 V class MxC of 5.5 kW is given.
