– The axis drive moves the seg-
ment to the 0-pulse and checks
the signal level for 3 digits.
– The axis runs in absolute posi-
tioning mode to one of the zero
pulses and check this zero
pulse. For a pick up angle of
90° the axis drive move direct
to the 90° black-bright transi-
tion.
– End signal is set when actual
position deviation is within al-
lowed deviation of position.
– There is no difference between
0° and 180° / 90° or -90° pick
up angle.

– When DP-station is swiveled in
the axiscontroller is activated
and ..
– .. the actual position is set to zero
by setting the position counter
DP-axis to 0.
– The DP-drive is operated in rela-
tive positioning mode.
– The DP-axis starts to the target
position taken from calibrated,
programmed and centered val-
ues.
– End signal is set when actual po-
sition deviation is within allowed
deviation of position.

6.3.24 Detailed turning process at DP-station - 3. Swiveling off
Fig. 6.3 - 21 Detailed turning process at DP-station - Swiveling off
– Start requirement for swiveling off is the end signal of DP-positioning.
– The DP-drive contact the sleeve. The positioning is finished with an end signal.
– The stepper motor is controlled by the light barrier on the cam disc.
– Picture 1 shows the swiveled in state.
– From the swiveled in state the stepper motor turn 90° counter clockwise to swivel off.
– Picture 2 shows the swiveled off state.
