220 Spd Observer BW
Sets the internal bandwidth for the speed feedback observer.
The setting should be as high a possible, preferrably at least 6
times the value of parameter 90 [Spd Reg BW]. A setting of
1000 rad/sec is reasonable for most applications. The speed
observer is bypassed when set to zero. Units:
