After the inital startup do the adjustments for closed-loop operation as follows:
1. Swtich off control release (terminal X2.1)
2. Select closed-loop operation
3. Adjust speed controller
Problem:
Very long transient process
Solution:
Increase P-fraction(CP.12); eventually
reduce I-fraction (CP.13)
Problem:
Sustained oscillation during constant run
Solution:
Decrease P-fraction (CP.12)
Problem:
Overshoot too long
Solution:
Increase I-fraction (CP.13)

Problem:
Speed overshoot too high
Solution:
Increase P-fraction (CP.12); eventually
reduce I-fraction (CP.13)
