Damping of the speed controller

The damping influences the target value overshoot magnitude and the decay
time constant of control loop oscillation.
Nominal value: 100%
On increasing the damping:
Overshoot decreases. High frequency oscillation of the servo drive takes place as
from a certain threshold value.
On decreasing the damping:
The target value overshoot of the actual value increases, and the actual value
oscillates for a longer time above and below the target value. As from a certain
threshold value the servo drive oscillates continuously.

Unit: % Range: 0 ... 500
The damping influences the target value overshoot magnitude and the decay time constant
of control loop oscillation.

Filter for speed value

Can be used to improve (filter) the rotation speed signal. The greater the value, the
stronger becomes the filter effect. However, the rotation speed delay increases
with this value, so that the maximum possible control loop dynamic range becomes
smaller with values which are too large.
Set the value to 0 when using motors with SinCos.
!
In the case of large load inertia in relation to the moment of inertia of the motor, a
!
large value can achieve further improvement in the attainable stiffness.
