The properties of the speed controller can be adapted for adjustment and optimiza-
tion of the controller. The amplification and integral time of the speed controller are
to be set via the parameters

The control deviation can be filtered with the
Therefore the operation with static control deviation with occasional undesired devia-
tions can be stabilized, while at the same time the dynamic behavior in load change
operation (speed change or changing torque demand) suffers.
The parameterized amplification at the current operating point can additionally be as-
sessed via the parameter
In particular the small signal behavior in applications with a gearbox can be improved
by a value higher than zero percent.

The default setting is relative to the recommended machine data for the amplifica-
tion and integral time. This enables a first function test in a large number of appli-
cations. Switch-over between settings 1 and 2 for the current frequency range is
done by the software according to the selected limit value.
