Adjusting Speed Control
Parameters
These settings show how to adjust the speed control for motor tuning.
Increase the bandwidth to obtain
faster speed response. If oscillation
occurs, decrease the bandwidth.
Speed Loop Bandwidth:
A511 [Freq 1 BW] = 10 Hz
A513 [Freq 2 BW] = 10 Hz
A515 [Freq 3 BW] = 10 Hz
For [Freq x Kp], gradually increase by 1%
For [Freq x Ki], gradually increase by 0.1 s
For general use, set A509
[Speed Reg Sel] to 0 (Automatic)
Set A509
