➠ Push the Z-axis down.
➠ Undo the two M1.6x3,2 slot screws (item 2 in Fig. 5.4 - 16).
➠ Loosen the M2x3 hexagon socket-head screw (item 5 in Fig. 5.4 - 16) of the cable clamp (item
4 in Fig. 5.4 - 16
).
➠ Undo the M2x5 hexagon socket-head screw (item 13 in Fig. 5.4 - 16) of the cable clamp
(item 12 in Fig. 5.4 - 16
).
➠ Undo the M2.5x4 hexagon socket-head screw (item 7 in Fig. 5.4 - 16) on the angled clip (item
6 in Fig. 5.4 - 16
) beside the star drive.
➠ Undo the M2.5x4 hexagon socket-head screw (item 9 in Fig. 5.4 - 16) on the angled clip (item
8 in Fig. 5.4 - 16
).
➠ Carefully pull the sensor and cable out of the front part of the collect&place head.
5.4.8.4 Installing the z-axis bottom sensor
➠ Thread the sensor cable from the Z-axis into the front part of the collect&place head.
➠ Fix the sensor (item 1 in Fig. 5.4 - 16) in position using the two M1.6x3,2 slot screws (item 2 in
Fig. 5.4 - 16
). Initially screw only loosely into the jaws for the Z-axis (item 3 in Fig. 5.4 - 16).
➠ Use the M2x3 hexagon socket-head screw (item 5 in Fig. 5.4 - 16) to fix the cable clamp for
light barrier 3 (item 4 in Fig. 5.4 - 16
) in place.
➠ Fix the cable in place using the cable clamp (item 12 in Fig. 5.4 - 16) in the driver (item 11 in
Fig. 5.4 - 16
).
➠ Fix the cable in place using the angled clip (item 6 in Fig. 5.4 - 16) beside the star drive.
➠ Check the cable run inside the front part of the collect&place head.
– When the Z-axis is pushed right out, the cable should lie loosely around the housing for the
star drive shaft. The cable must NOT be pulled tight.
– When the Z-axis is pushed right in, the cable should run freely inside the front part of the
collect&place head without touching the rotary encoder for the DP-axis.
CAUTION
If the radius of curvature is too small, the Z-axis may become jammed or the light barrier
cable may break. 5
If the cable run meets the two conditions above, fix the cable in place using the angled clip
(item 8 in Fig. 5.4 - 16
). 5
➠ Insert the plug connector for the cable into socket X11 on the intermediate terminal block.
