This FB generates a position difference for the defined position setpoint from a position
value and a speed signal.
In an integrator, the nIn_v speed signal is integrated into a position value and
subtracted from the dnSet_p position setpoint.
In addition, the adaptive dnAdd_p position value can be added to the integrator
content by setting bEn to TRUE.

FALSE 1.The speed signal at nIn_v is integrated by the angle integrator.
2.The result of the angle integrator is subtracted from the angle
signal at dnSet_p and output at dnOut_p afterwards.
TRUE The adaptive position value selected via dnAdd_p is added:
1.The speed signal at nIn_v is integrated by the angle integrator.
2.The angle signal at dnAdd_p is added to the integrated speed
signal in every task cycle.
3.The result of the angle integrator is subtracted from the angle
signal at dnSet_p and output at dnOut_p afterwards.
