Enter the numerator bandwidth for control output filters 1...2 (damped bandstop)
in the velocity controller. Entering a value of 0 initializes the filter as an unatte-
nuated bandstop filter.
The filters are activated in MD 5200: NUM_OUTPUT_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).
