Step response of the velocity loop depending on the optimization parameter
"attenuation" and "stiffness"
Attenuation = 100%
Stiffness = 100%
1: Setpoint value
2: Actual value (stiffness = 200%)
3: Actual value (stiffness = 100%)
4: Actual value (stiffness = 50%)
5: Actual value (attenuation = 500%)
6: Actual value (attenuation = 100%)
7: Actual value (attenuation = 50%)
D-term
The D-term parameter ( of the velocity loop) activates existing control oscillations of
drives with elastic coupling (e.g. toothed belt drives). The D-term is not
automatically designed and must therefore be set manually.
Position loop
The position controller is automatically adapted depending on the stiffness of the
velocity loop.
