Speed-up function
Withloadshavingahighmomentofinertiaitispossibletocheckthejumpsduringthespeedchanges.Theycan
bereducedusingthefunction“Speed-up”.Thegures5.3.7.3and5.3.7.4showtheinuenceofthisfunction.
Figure 5.3.7.3: Above: Actual spd; Below: Motor current jumps with the speed
changes due to a high moment of inertia. The function Speed-up is not active.
Figure 5.3.7.4: Above: Actual spd; Below: Motor current. The same drive with
Speed -up function active.
Parameters used in the example:
Speed up base  14ms
Speed up gain  50%
Speed up lter 20ms
Setting of the speed zero logic
- Thespeedzerologicisfactorysetasdisabled.Seesection6.7.2,“Speedzerologic”,foradescriptionof
thedrivebehavior.
- DisableoftheI-sectionofthespeedregulatorwithn=0:
I-sectiondisabled:      Enable spd=0 I=Enabled
I-sectionenabled:      Enable spd=0 I=Disabled
note!  Whenthemotorisatastop,itispossibletoavoidthecreepofthedrivedisablingtheIsec-
