Manual Lowering of Z Axis Settings
Student Guide SIPLACE X-Serie and X4I SW70x (AL2) 344
Manual Lo wering of Z Axis
9.4.3 Manual Lowering of Z Axis
The TwinHead is designed for a placement force of 0.5 to 15 N (to 30 N for high-force TwinHead)
The rotary axis needs to be very smooth-running, especially for low placement forces. Therefore, the
rotary axis is not constructed for traction forces.
Since both segments of the TwinHead are fitted at an angle of 180°, there are two different methods for
moving the Z axis downwards.
CAUTION
When manually lowering the Z axis, the TwinHead module can be easily damaged!
► Manual lowering may only be performed by trained personnel!
CAUTION
Before performing manual lowering of the Z axis, make sure the Z axis has been released at
the relevant axis controller board.
► When releasing the Z axis, the Z axis return cylinder moves upwards.
► If the axis is not released, the return cylinder will automatically move upwards when the Z
axis is manually lowered, which could cause injuries and damage to the placement head.
Lowering the Z Axis at P&P Module 1
To safely press the Z axis downwards, apply manual
pressure to the marked part of the retract unit driver.
Lowering the Z Axis at P&P Module 2
The Z axis can be moved downwards at segment 2 by
taking hold of the carrier arm from both sides and then
pushing this down.

Function Description
9.5.2 Function Description
The magazine for standard nozzles has 1 positioning fiducial for position detection, while the magazine
for special nozzles/grippers has two positioning fiducials. The nozzles are fixed by balls in the holder.
They are then either locked for return or released for pickup, depending on the direction of rotation of the
D axis.
Fitting the magazine (X/D3 machine)
The nozzle changer together with the empty tape duct is
fixed on the component docking unit. The magazines are
seated on a common support. They are centered with two
parallel pins and fixed in place with two countersunk
screws.

9.5.3 Nozzle Changer for TwinHead
All SIPLACE machines configured with a TwinHead are delivered with a nozzle changer by default. This
nozzle changer can accommodate up to 12 nozzle magazines. There are two types of magazine
available: standard magazines and magazines for special nozzles or grippers. Depending on the
machine type the nozzle changer can be freely configured with magazines. The nozzle changer consists
of a standard module with 3 nozzle garages, for two nozzles each (standard nozzles) and one nozzle
garage for a special nozzle. This configuration can be extended as shown in the diagram below.

NOTICE
The magazines for standard and special nozzles are freely configurable with SW 505 or higher.
