1) Applied ​motor ​indicates the maximum capacity applied for use of a standard 4-pole standard motor.

2) Rated Capacity: The input capacity of a 200V class is based on 220V and a 400V class is based on 440V. The current rating is based on the CT current.

3) The output of the rated current is limited according to the setting of the carrier frequency (CON-04).

4) The frequency can be set up to 300Hz by selecting 3, 4 Sensorless-1, or Sensorless-2 as the control mode (DRV-09 Control Mode).

5) The maximum output voltage does not go over the supplied power voltage. The preferred output voltage can be selected below the supplied power voltage.
