This parameter is the r.m.s. input current to the drive. The phase currents consist of an active component and a reactive component. The three phase
currents can be combined to form a resultant current vector as shown below:

The resultant current magnitude is displayed by this parameter. The active current is the torque producing current for a motor drive and the real
current for a Regen drive. The reactive current is the magnetising or flux producing current for a motor drive.

The active current is the real current in a Regen drive.
Direction of active current
+
-
The active current is aligned with the y axis of the reference frame. The y axis of the reference frame is aligned with the Regen drive terminal voltage
vector.
