After initial start-up the following adjustments must be done:
1.
Switch off control release (terminal X2.1)
⇒
Inverter in status „noP“
2.
Select closed-loop operation
⇒
Parameter CS.23
3.
Adjust speed controller
⇒

7.2.2
Start-up (closed-
loop)
Problem:
Sustained oscillation with high amplitude
Solution:
Reduce I-fraction (CS.01)
Problem:
Very long transient process, but stabilization
during constant run
Solution:
Increase P-fraction (CS.00); eventually
reduce I-fraction (CS.01)
Problem:
Speed overshoot too high
Solution:
Increase P-fraction (CS.00); eventually
reduce I-fraction (CS.01)
Problem:
Sustained oscillation during constant run
Solution:
Decrease P-fraction (CS.00)
Problem:
Transient too slow / remaining system
deviation
Solution:
Increase I-fraction (CS.01)
Problem:
Overshoot too long
Solution:
Increase I-fraction (CS.01)
