Speed Regulator
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.
