2.12.7 Speed controller

The speed controller is designed as an ideal PID controller.

Parameter setting

By selecting a motor under C0086 the parameters are preset, making most adaptations to the

application unnecessary.

 The proportional gain V

can be set under C0070:

– Enter approx. 50 % of the speed setpoint (100 % = 16384 = N

max

– Increase C0070 until the drive becomes unstable (pay attention to motor noise)

– Reduce C0070 until the drive runs stable again.

– Reduce C0070 to approx. half the value.

 The reset time T

can be set under C0071:

– Reduce C0071 until the drive becomes unstable (pay attention to motor noise).

– Increase C0071, until the drive runs stable again.

– Increase C0071 to approx. twice the value.
