6.6.5 Calibrating the D Axis Pick&Place Head
Service Manual SIPLACE D1/D1i/D2/D2i 249
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.

Pick&Place Head 6.6.5 Calibrating the D Axis
250 Service Manual SIPLACE D1/D1i/D2/D2i
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.

SITEST:
► Select P&P module.
► Select Axis functions.
► Select the checkbox D-Axis.
► Select Positions...
► 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])

6.6.7 Calibration of Vacuum Distributor on the P&P Head
Calibration of Vacuum Distributor on the P&P Head
The vacuum distributor is part of the P&P head and creates the vacuum and air blast for the pick up and
placement process. The zero calibration of the vacuum distributor should be performed on initial setup
at the customer site and after replacing the vacuum distributor or P&P head.
If you do not calibrate the vacuum generator, you will have incorrect threshold values for calculating the
"No component on the nozzle or nozzle is dirty" value.
With the aid of the zero calibration the motor of the vacuum generator is positioned into a middle or neu-
tral position, so that there is no vacuum or air blast present at the nozzle.

Make sure that the 517 nozzle is on the P&P head and has been entered.
The zero point correction, plus the maximum and minimum travel range for the Z axis will be
correctly set after performing "head height" calibration.
