Description
This parameter reads the measured, de-rotated actual current value of the motor.
Note: Internally the resolution of the current scale is 20130 increments. For an AKD PDMM
with a peak current of 9 amps, the current resolution applied is 9/20130 = .447 mA. For a 48
amp peak current drive, the resolution is 48/20130 = 2.38 mA. The current scaling is hard coded
and cannot be changed by decreasing the peak current settings in the drive.

Description
This parameter selects the feedback source that current loop use for commutation angle cal-
culation.
0 = Primary feedback
1 = Secondary feedback
For induction motor closed loop control the commutation angle is set as shown in the following
figure.
