8.4.5 Speed controller
The speed controller is automacally set if one of the following opmisaons is carried out:
4Motor selecon from motor catalogue ^ 144
4Automac motor idencaon (energized) ^ 146
4Automac motor calibraon (non-energized) ^ 147
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.
Details
The speed controller has an inuence in the following motor control types:
•
Sensorless control (SL PSM)
•
Sensorless vector control (SLVC)
The automacally calculated sengs for the speed controller enable an opmal control
behaviour for typical load requirements:
•
Minimum speed loss
①
•
Minimum seling me
②
•
Minimum overshoot
③
Speed
Load requirement
Speed setpoint
Seng notes
If oscillaons occur during operaon aer high load requirements:
•
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 load
requirements:
•
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!
