Dynamic Servo Control (DSC)
The PROFIdrive profile contains the "Dynamic Servo Control" control concept. This requires
application class 4 and transfers not only the speed setpoint, but also the KPC position
controller gain factor and the XERR system deviation. With the aid of this data, the position
controller can be calculated in the drive. The position setpoint interpolation is still performed
in the controller. This can be used to significantly increase the dynamic stability of the
position control loop in application class 4.
