Parameters 11-49
160 Kf Speed Loop
Use Kf Speed Loop to control the feed forward gain of the speed
regulator. Setting the Kf gain to less than one reduces speed
feedback overshoot in response to a step change in speed
reference.
Parameter number 160
File:group Control:Speed Regulator
Parameter type linkable destination
Display x.xxx
Factory default 1.000
Minimum value 0.500
Maximum value 1.000
Conversion 65535 = 1.0
161 Spd Desired BW
Use Spd Desired BW to specify the speed loop bandwidth and to
determine the dynamic behavior of the speed loop. As you
increase the bandwidth, the speed loop becomes more
responsive and can track a faster changing speed reference.
As you adjust the bandwidth setting, the 1336 IMPACT drive
calculates and changes Ki Speed Loop (parameter 158) and Kp
Speed Loop (parameter 159) gains. A zero bandwidth setting lets
you adjust the speed loop gains independent of bandwidth for
custom tuning applications.
Note: You must have the correct Total Inertia (parameter 157)
entered before adjusting the speed loop bandwidth. Total Inertia
is measured by the autotune (startup) routine.

pass lters in the Kf error path of the speed PI regulator.
