Speed controller optimization
The additional smoothing functions in the speed controller loop (damping me-
chanical resonance effects) are described in Section 3. Proceed as follows
when optimizing the speed controller:
4. Tachometer adjustment
5. Gain Kp
6. Integral action time T
7. Adaptation T
8. I–component limiting
9. Drift compensation (offset)
The unit must be powered–up to optimize the speed controller
Therefore please refer to p. 1-121 "Power–on".
The potentiometer scale divisions (in the setting tables) are defined as follows:
1-96
