5.5.3.2 Optimising the speed controller

To optimise the speed controller, the drive must be accelerated in the base speed range with slow

setpoint ramps (e.g. acceleration time = 5 s) to speed values below the rated speed and then

decelerated again.

Gain optimisation

The proportional gain Vp is selected under C00070

:

1. Increase C00070

until the drive oscillates slightly (see picture [5-11]).

2. Reduce C00070

until the drive runs stable again (see picture [5-12]).

3. Reduce C00070

to approx. half the value.

Optimise the reset time

The reset time Tn is selected under C00071

:

1. Reduce C00071

until the drive oscillates slightly.

2. Increase C00071

until the drive is stable again.

3. Increase C00071

to approx. double the value.
