Very long transient process
Increase KP speed (CP.30); eventually
reduce KI speed (CP.31)
Sustained oscillation short billowy,
noises, vibes
Decrease KP speed (CP.30)
Overshoot too long, strong speed
decreases at load change
Increase KI speed (CP.31)
=>
frequency inverter in status „noP"
=>
Parameter CP.10 = 4
Problem
Very long speed overshoot
Increase KP speed (CP.30);
Solution
eventually reduce KI speed (CP.31)
Transient too slow / remaining system
Problem
deviation
Increase KI speed (CP.31)
Solution
Problem
Sustained oscillation long billowy
Solution
Reduce KI speed (CP.31) and / or
reduce KP speed (CP.30)
