Dynamic Servo Control (DSC)
The PFOFIdrive profile contains the "Dynamic Servo Control" control concept. This can be
used to significantly increase the dynamic stability of the position control loop in application
class 4 with simple means.
For this purpose, the deadtime that is typical for a speed setpoint interface is minimized by
an additional measure (see also chapter "Dynamic Servo Control").
