The actual value parameter
The revolutions of the motor displayed should correspond to the
quired position.
The minimum number of revolutions needed until the required position is reached depends on the

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 stand-
still at the required position. This is the minimum value for the
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.
461 Signal correction
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 posi-
tive figure for the
Signal correction
