10.7.6.1 Speed controller
For a quick commissioning, the calculaons and sengs are made automacally during the
opmisaon.
For typical applicaons, a manual adaptaon of the parameters of the speed
controller is not recommended. A wrong seng may have a negave eect on
the control. For special applicaons, contact the manufacturer before adapng
the parameters.
The automacally calculated sengs for the speed controller enable an opmal control
behaviour for typical load requirements. The oscillographed actual speed value (red) shows
the control mode.

1 Minimum speed loss
2 Minimum seling me
3 Minimum overshoot
Seng notes
If oscillaons occur during operaon aer high loads:
•
Reduce gain of the speed controller in 0x2900:001 (P332.01).
•
Increase reset me of the speed controller in 0x2900:002 (P332.02).
If the speed loss is too high or the seling me too long during operaon with high loads:
•
Increase gain of the speed controller in 0x2900:001 (P332.01).
If the gain is set too high or the reset me too low, the speed control loop can
become unstable!
