4.4.4.2
Velocity loop damping
Nominal value: 100%
The damping influences the Setpoint value overshoot magnitude and the
decay time constant of control loop oscillation.
Overshoot decreases. High frequency oscillation of the servo drive takes place as
from a certain threshold value.
On increasing the damping:
The Setpoint value overshoot of the actual value increases, and the actual value
oscillates for a longer time above and below the Setpoint value. As from a certain
threshold value the servo drive oscillates continuously.
On decreasing the attenuation

2100.3: Velocity loop damping
Unit: %
Range: 0 ... 500
Standard value: 100%
The damping influences the Setpoint value overshoot magnitude and the decay time
constant of control loop oscillation.
4.4.4.3
Filter - Actual velocity
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.
If you use motors with high-quality feedback systems (SinCos

SineCosine feedback) and low vibration mechanics, set the value to 0.
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.
2100.5: Filter - Actual velocity
Unit: %
Range: 0 ... 550
Standard value: 100%
This is used to improve signals (filtering) of the speed control signal
