The gantry is fixed to the two shuttles (see item 1 in Fig. 4.2 - 3
) of the recirculating ball screw unit
(see item 2 in Fig. 4.2 - 3
) using four M6 x10 hexagon socket-head screws. 4
The secondary part (see item 3 in Fig. 4.2 - 3
) of the Y-axis linear drive, with its permanent mag-
nets, is located above the guide rail of the recirculating ball screw unit. The secondary part is
mounted on the machine frame. 4
The air and power supply and signal lines for the gantry and collect&place head all run in a trailing
cable (see item 1 in Fig. 4.2 - 4
). 4

The seven power cables take the form of flexible ribbon cables, four of which are needed for the
collect&place head. They run beneath the cover in the machine frame (see item 1 in Fig. 4.2 - 5
),
between the head board on the head mount and the gantry board. 4
