5.4.1.2 Optimising the speed controller
The speed controller is designed as PID controller.
Gain setting
The proportional gain Vp is selected under
C00070 :
1. Select the speed setpoint.
2. Increase C00070 until the drive becomes unstable (observe motor noises).
3. Reduce C00070 until the drive becomes stable again.
4. Reduce C00070 to approx. half the value.
Reset time setting
The reset time Tn is selected under
C00071 :
1. Reduce C00071 until the drive becomes unstable (observe motor noises).
2. Increase C00071 until the drive is stable again.
3. Increase C00071 to approx. double the value.
Rate time setting
The rate time Td is selected under
C00072 :
• Increase C00072 during operation until an optimum control behaviour is reached.
