5.11: Current Loop
Initial current loop proportional gain (
Cp
) and current loop integral gain (
Ci
) values were calculated
in a previous step. For an introductory overview of the control loops, see
Operating Modes (p. 19)
.
NOTE: For Copley Controls digital amplifiers, the current loop gain is independent of the power
supply voltage.
