The properties of the speed controller can be adapted for adjustment and optimization of the
controller. The Amplification and Integral Time of the speed controller can be set via parameters

with static control deviation and occasional undesired higher deviations can be stabilized. However,
this will affect the dynamic behavior when the load changes (speed change or changing torque
requirements).
The parameterized amplification at the current operating point can additionally be assessed via the

gearbox can be improved by a value higher than zero percent.

The controller is deactivated or the torque-forming component is
zero.
The limitation of the speed controller assigns the upper limit to the
motor operation of the drive. Independent of the direction of
rotation, the same limit is used. The same applies in the case of
regenerative operation with the lower limit.
The assignment of the limit is done by the sign of the value to be
limited. Independent of the motor or generator operating points of
the drive, the positive limitation is done by the upper limit. The lower
limit is regarded as a negative limitation.
