➠ Make sure that the contact surfaces of the turning station and rear panel are clean.
➠ Insert the M3 x 25 hexagon socket-head screw (item 2 in Fig. 11.2 - 1) into the hole in the
centering station.
➠ Run the cable between the vacuum hose and the vacuum generation socket.
➠ Place the holes in the turning station on the parallel pins.
➠ Carefully push the turning station towards the back part until it reaches the stop.
➠ Fix the turning station with the hexagon socket-head screw.
➠ Plug the cable into sockets X12 and X18 on the head board (see item X12 and X18 in Fig.

➠ Switch the placement system on and start it up.
➠ Use the SITEST program to run a function test.

The stepper motor, which acts to swivel out the drive O-ring to engage with the segment sleeve,
is controlled and monitored by the Machine Controller via the CANBUS. When the Star axis is in
position, and the axis ’End Signal’ is sent to the Machine Controller, the Machine Controller gives
the command to swivel out. The stepper motor rotates 90° to engage with the sleeve, the slotted
light barrier monitors this movement and when it is complete the signal is reported back to the Ma-
chine Controller.
The Machine Controller now sends the 'Servo Enable' command to the Axis Controller and as a
result the drive motor will start and rotate the sleeve to the required position. Once the axis card
measures that the position is correct it then gives the 'End Signal' to the Machine Controller. The
command is then sent to the stepper motor to swivel back the drive system that does so by re-
versing 90° back to it's home position. Again when this movement is complete the signal is sent
back to the Machine Controller.
These functions can be tested using the 'Single Funtions' tests in the SITEST program.
½ The Dp swivel motor is controlled by
the machine controller via the
CANBUS.
½ The swivel motor position is detected
by a slotted light barrier which monitor
the disk fitted to the motor shaft.
½ The axis controller is enabled with the
“swiveled in signal”sent to the machine
controller via the CANBUS.
½ The axis controller is disabled with the
“swiveled off signal”sent to the machine
controller via the CANBUS.
½ The position is directly measured on
the sleeve by the encoder looking at the
scale.

The stepper motor of the valve drive is turned to the home position. The stepper motor runs and
the light barrier on the cam disk sets the end signal.
Because of the special shape of the cam disk the stepper motor is able to recognize the home
position.
