Adjustment Speed Controller of F5 Lift with "speed jump"

1. Open control release (terminal X2A.16)
2. Select closed loop operation
3. Motor without load
4. Set parameters LF.30, LF.31, LF.32 to maximum values
5. Give drive command and measure ru.02/ LI.03 and ru.09/ LI.04

Problem
Solution
Very long transient process
Increase KP speed (LF.11); eventually
reduce KI spped (LF.12)
Sustained oscillation short billowy,
noises, vibes
Decrease KP speed (LF.11)
Overshoot too long, strong speed
decreases at load change
Increase KI speed (LF.12)
=> frequency inverter in status „noP"
=> Parameter LF.10 = 2
Problem Very long speed overshoot
Solution Increase KP speed (LF.11); eventually
reduce KI spped (LF.12)
Problem Transient too slow / remaining system
deviation
Solution Increase KI speed (LF.12)
Problem Sustained oscillation long billowy
Solution Reduce KI speed (LF.12) and / or
reduce KP speed (LF.11)
