445 [Ki Speed Loop]
Controls the integral error gain of the
speed regulator. The drive automatically
adjusts [Ki Speed Loop] when a non-zero
value is entered for [Speed Desired BW]
or an autotune is performed. Typically,
manual adjustment of this parameter is
needed only if system inertia cannot be
determined through an autotune. [Speed
Desired BW] is set to “0” when a manual
adjustment is made to this parameter.

446 [Kp Speed Loop]
Controls the proportional error gain of the
speed regulator. The drive automatically
adjusts [Kp Speed Loop] when a
non-zero value is entered for [Speed
Desired BW] or an auto-tune is
performed. Typically, manual adjustment
of this parameter is needed only if
system inertia cannot be determined
through an autotune. [Speed Desired
BW] is set to “0” when a manual
adjustment is made to this parameter.

447 [Kf Speed Loop]
Controls the feed forward gain of the
speed regulator. Setting the Kf gain
greater than zero reduces speed
feedback overshoot in response to a step
change in speed reference.
Default:

449 [Speed Desired BW]
Sets the speed loop bandwidth and
determines the dynamic behavior of the
speed loop. As bandwidth increases, the
speed loop becomes more responsive
and can track a faster changing speed
reference.
Adjusting this parameter will cause the
drive to calculate and change [Ki Speed
Loop] and [Kp Speed Loop] gains.
