SPEED COMMAND (file C)
Speed Regulator
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 causes the drive to
calculate and change P445 [Ki Speed Loop] and
P446 [Kp Speed Loop] gains.

450 [Total Inertia]
Represents the time in seconds, for a motor
coupled to a load to accelerate from zero to
base speed, at rated motor torque. The drive
calculates Total Inertia during the autotune
inertia procedure.
Adjusting this parameter causes the drive to
calculate and change P445 [Ki Speed Loop] and
P446 [Kp Speed Loop] gains.
