– Follow the Information and press the Start button on the maschine.

–Press OK

Now the head is calibration the Z- and Star zero point correction and save the new values in the

Achs_ver.ma and on the EEprom.

NOTE :Is this function not successful, please check the Travel range of the Z-axis.

The max. and min. travel range of the Z-axis(C&P20) are 34000 digits and -200 digits.

Function description: 11

– The Z-Axis move up with the current sensor mode and set the counter to 0.

– Then the Z- axis moves down to 18000 digits until the ball bearing of the Z- axis is between the

raceway of the star axis.

– The star turns left and right and calculated the average value. This is the new zero point cor-

rection (

zpc) value of the star axis.

– The Z- axis moves further down until the ball bearing (Segment) is in the center of the raceway

gap.

– The star turns right into the gap of the raceway and the Z- axis push up the ball bearing against

the raceway. The Z-axis position is read.

– Now the Z- axis position is read on the left side from the raceway gap with the same procedure,

like the right side.

– Afterwards the new zero point correction of the Z- axis is calculated in the following way :

Z- position - diameter ball bearing - thickness of the raceway = new zpc Z- axis

NOTE : The data is directly stored in the Achse_ver.ma and in the EEPROM of the head.

11.2.4 Calibration positions in the machine

Fig. 11.2 - 2 Top view of machine

Key:

(1) Transport direction

(2) Fixed PCB corner BB 1/ 2 Track 1 and 2

(3) Machine zero point BB 1

(4) Calibration position BB 1 (depend on the head type)

(5) Machine zero point BB 2

(6) Calibration position BB 2 (depend on the head type)

Note:

Some calibrations require that you attach nozzles on the placement heads.

Use nozzles of type

956 for C&P6/12, 1235 for C&P20 and for the Twin head 517. Make sure that

all nozzles have been attached correctly, otherwise measuring will lead to incorrect results.

If you need to, place the calibration tool into the "calibration pocket". (Fig. 11.2 - 2).

Before you place the calibration tool, make sure that it is clean. Also, be sure that you insert it into

the "calibration pocket" with its print of the fiducial structure on the bottom. 11
