Adjustment Instruction Speed Controller - KEB COMBIVERT F5 - Serie Betriebsanleitung

Adjustment instruction speed controller

5. Adjustment instruction speed controller
With the PC software KEB COMBIVIS (Scope) set and real speed can be displayed. If one of the
following real speed curves occurs at acceleration, the speed controller (CP.30, CP.31) should be
adjusted according to the notes.
Problem: Very long transient process
Solution: Increase KP speed (CP.30); eventually
reduce KI speed (CP.31)
Problem: Sustained oscillation short billowy, noises,
vibes
Solution: Decrease KP speed (CP.30)
Problem: Overshoot too long, strong speed
decreases at load change
Solution: Increase KI speed (CP.31)
Problem: Speed overshoot too high
Solution: Increase KP speed (CP.30); eventually
reduce KI speed (CP.31)
Problem: Transient too slow / remaining system
deviation
Solution: Increase KI speed (CP.31)
Problem: Sustained oscillation long billowy
Solution: Reduce KI speed (CP.31) and / or reduce
KP speed (CP.30)
