Chapter 4 Parameter SettingsDD Series

NOTE

;In torque/vector control mode, it is not recommended to have motors run in parallel.

;It is not recommended to use torque/vector control mode if motor rated power exceeds the rated power of the AC motor drive.

;The no-load current is usually 20~50% X rated current.

;The rated speed can not be greater than or equal to 120f/p (f=rated frequency Pr.01-32; P: number of motor poles Pr.01-15).
