0...7 index of the parameter set

0...7 index of the parameter set
Minimum: Maximum:

Input of –3dB bandwidth for control output filters 1...2 (bandstop) in the velocity
controller.
The filters are activated in machine data MD 5200: NUM_OUT-
PUT_VCTRL_FILTERS and MD 5201: OUTPUT_VCTRL_FILTER_CONFIG.
0...7 index of the parameter set
Minimum: Maximum:
0.0 7999.0
0...7 index of the parameter set
Minimum: Maximum:
0.0 7999.0
Input of numerator bandwidth for control output filters 1...2 (damped bandstop)
in the velocity controller. Setting a value of 0 initializes the filter as an undamped
band-stop.
The filters are activated in machine data MD 5200: NUM_OUT-
PUT_VCTRL_FILTERS and MD 5201: OUTPUT_VCTRL_FILTER_CONFIG.
The DSC (Dynamic Stiffness Control) function is supported, allowing higher P
gain settings in the position controller. The function is implemented in the same
way as on an electrical drive. It is also activated via the control system (as on an
electrical drive).
