Example: f = 20 Hz, a = 5 Hz/s, p = 2  U
With an actual frequency of 20 Hz and a delay of 5 Hz/s, at least 20 rotations are needed until
standstill at the required position. This is the minimum value for the
shorter positioning distance is not possible. If the number of rotations until the required position is
reached is to be lower, the frequency must be reduced, the deceleration increased, or the reference
point must be shifted.
The digital signal for registration of the reference point and the logical assignment are to be chosen

The signals for positioning and a stopping behavior should not be assigned to the same digital input.

The registration of the reference position via a digital signal can be influenced by a variable dead
time while the control command is read and processed. The signal running time is compensated by a
positive figure for the

The influences on the positioning which depend on the operating point can be corrected empirically

the Load correction
duration is increased by a positive load correction value. The distance between the reference point
and the required position is extended. Negative values accelerate the braking process and reduce
the positioning distance. The limit of the negative signal correction results from the application and
