Note 1. The upper limit of the setting range and the factory setting for the 400-VAC class
are double the above values.
Note 2. The setting range and factory setting for n31 (electronic thermal reference cur-
rent) depend on the Inverter model. For details, refer to page 4-19.
Normally, set the rated motor amperage in n31.
