8.2 Reference Run

The C&P20 head has 3 axis types: the Z-axis, Star axis and DP axes, pluse the X and Y axes for

the gantry. Before starting production, all axes must be initialized, so that the axis controller can

locate their actual mechanical positions. The software start procedure first loads the DP master

firmware and then rotates the DP axes into the 0° position.

General sequence 8

– With a few exceptions, this reference run principle is the same as that of the DLM2 6 and 12

nozzle C&P heads. However, stepping motors are no longer to initialize, as the C&P20 head

is equipped with a pressure control valve for vacuum and air kiss and each segment has its

own DP drive. For this reason, the functions previously performed by the stepping motor are

now redundant.

– In Siplace X machines, all heads C&P head, TWIN head make the reference run at the same

time, the gantry axes follows.

Reference run for X/Y axes

Initializes head axes

(Star, Z, DP axes)

The X/Y axes move head to reject

position

Rejects component with cleaning pulse

for all segments, if necessary

The X/Y axes move the head to the fixed conveyor side

Nozzle height and closed vacuum is measured for

all segments.

Conveyor reference run

The X/Y axes move to wait position.

8.2.2 Preparing the Z-axis Reference Run

Fig. 8.2 - 2 Preparing the Z-axis reference run (C&P20)

The retract unit on the C&P20 head of the Z-axis ensures that the Z-axis is already in a safe po-

sition after the machine has been started up. This means that the star can be rotated properly dur-

ing the reference run, without the need for a prior reference run of the Z-axis.

8.2.3 Star Axis Reference Run

Fig. 8.2 - 3 Star axis reference run

The star axis rotates in an anticlockwise direction (1) to the zero point pulse of the incremental

encoder. After the star axis reach the zero point pulse, the zero point correction factor is loaded

and the star axis rotates in a clockwise direction

(2) (according to the zero point correction factor)

until the position and set the counter to 0 digits.
