Initial Start-up
Chapter Section Page Date
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 ⇒ see adjustment tips below
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)
