correctly set
- Check the value for the current limitation
- The value for Magnetizing curr and/or Rotor resistance parameters is not
correct. Optimize the tuning as described in the instruction book.
The speed during acceleration with maximum current is not linear
Reduce the Speed I and Speed P proportionally. If this does not lead to an im-
provement, optimize the regulator.
Speed oscillating Check Speed P and Speed I parameter
If the operating point is in the field weak range, check the Flux P and Flux I
parameters
Incorrect value for Rotor resistance
Remedy: Optimize the tuning as described in the AVy instruction book on CD.
