P&P Head Parameters
Parameter force sensor and spring pre-tension
SITEST:
Select P&P module
Select Axis functions
Select the checkbox Z axis.
Select the Parameter... menu and enter the values
Force sensor comparative value in [mV/V]. This value is always smaller than 3.0 [mV/V].
and Spring pretension in [mN]. (this value is between 300 and 700 [mN]).
If the values are not entered according to the data on the P&P head in SITEST, determination of the
placement force will not be correct between the 1 and 15 N.
Zero point correction (ZPC) D axis
SITEST:
Select P&P module
Select Axis functions
Select the checkbox D axis
Select Positions...
Disable the checkbox Use digit unit.
Mark the required line and select Edit.
Enter the relevant ZPC value in 1/100 degrees and select Accept.
Confirm your entry with Accept.
Perform a reference run for the D axis.
Do not forget to perform D axis calibration afterwards.
Label with D axis correction value and parameters for
P&P head
Legend
Each P&P head has a label with corrective values, which
needs to be entered after initial operation or after replac-
ing the head in SITEST.
1. Sensor (parameter for the DMS strips)
2. Spring (spring pre-tension)
3. DP (zero point correction D axis)
NOTICE
DO NOT adjust the setting screw (fine thread) for the spring pre-tension! It is currently not pos-
sible to measure the spring pretension at the customer site, meaning that the placement head
needs to be replaced.

Zero point correction (ZPC) Z axis
SITEST:
Select P&P module
Select Axis functions
Enable Z axis
Select Positions... and enter the following values:
(switch off display in digits)
⇨ max. travel range (position): 57500 µm
⇨ max. travel range (position): -2000 µm
⇨ Zero point correction: 0 µm
==> Perform a head height calibration (ZPC for the Z axis).
Calibrate the head height of the P&P head. Switch over to the Calibrate Head.

6.6.5 Calibrating the D Axis
Calibrating the D Axis
Put the calibration nozzle for the TWIN Head/P&P head manually at the P&P head sleeve. Make
sure that the two adjust pins engage properly in the nozzle.
Perform an axis reference run for the D axis.
Now check the alignment of the nozzle:
The drilling on the calibration nozzle must point to the center (SW 505 or higher) of the machine (for
SR/MC 504.0x to machine outside) and the nozzle must be aligned parallel to the PCB conveyor.
Assign the nozzle "516" for the P&P head to be calibrated:
SITEST:
Select P&P module
Select the nozzle changer head function.
Select the appropriate "segment" from the list.
Select Edit ==> mark "516" and select Accept.
Enable Select Segment.
Select Confirm Exchange.
NOTICE
Only enter the standard values for the Z axis if the reference run or the calibration of the head
height was not successful.
NOTICE
Make sure that the 517 nozzle is on the P&P head.
NOTICE
The zero point correction, max- and min. travel range of the Z axis is determined when you cal-
ibrate the head height.
NOTICE
The exact zero point correction (ZPC) of the D axis is automatically calibrated on the SIPLACE
HF/HF3 with a calibration nozzle.
Correct calibration can only be expected if the ZPC angle differs less than +/- 5 degrees from
the real value.

SITEST:
Select P&P module
Select Calibration Functions
Open the Calibrate Zero Point DP Axis menu.
When requested to do so by the SW, connect the D axis calibration nozzle.
The ZPC will be automatically determined through the angle recognition of the nozzle outline.
Repeat this procedure until the new value does not deviate more than +/- 0.01° from the previous
value.

Set the zero point correction to 0.
Perform an axis reference run for the D axis.
Put the calibration nozzle for the TWIN Head/P&P head manually at the P&P head sleeve. Make
sure that the two adjust pins engage properly in the nozzle.
Enable the D axis of the P&P head at the axis card.
Manually rotate the nozzle into the zero position:
The drilling on the calibration nozzle must point to the center (from SW 505 onwards) of the machine
and the nozzle must be aligned parallel to the PCB conveyor.
In order to display the position of the D axis, open the Z axis menu by checking the checkbox and
then return to D axis.
Enter the value shown for the D axis as the zero point correction value.
Activate the D axis of the P&P module at the axis card.
Perform an axis reference run for the D axis.
Now check the position of the nozzle:
The drilling on the calibration nozzle must point to the center (from SW 505 onwards) of the machine
and the nozzle must be aligned parallel to the PCB conveyor.
Do not forget to perform D axis calibration afterwards. (see "6.6.5 Calibrating the D Axis" [ 249]).
NOTICE
If the calibration is not successful, you can roughly determine the zero point correction manually
and enter this value. (see "6.6.5.1 Manual Calculation of the D Axis Zero Point Correction"
[ ➙ 250])
