6.1 Reference Run (D/Di-Series)
Reference Run (D/Di-Series)
The placement machine reference run guaranties the correct function for placement in the station SW.
In diesem Kapitel wird der Referenzlauf für C&P-Kopf und Portal beschrieben. Danach wird der parallel
zum C&P-Kopf ausgeführte Referenzlauf zum P&P-Modul beschrieben.
6.1.1
6.1.1 Overview
Overview
The reference run is divided into 4 main steps. Module reference runs for the WPC or for a 2nd place-
ment head per gantry are not listed at this stage.
1. Conveyor system reference run
This activates the unoccupied (not occupied with a PCB) conveyors.
(in older SW versions, this function can also be performed to conclude the reference run.)
2. Axis reference run
This is divided into:
A.) the head axis reference run and
B.) the gantry axis reference run.
The gantry head axes are started at the same time. As many functions as possible are performed at
the same time.
3. Vacuum reference run
The
A.) vacuum values "open" and "closed" for placement are determined and
B.) all segments in the DP stations are rotated into their 0 degrees positions.
4. Height reference run
This function tests the length of the segment nozzles and of the heads in a placement area, on the
top surface of a conveyor side.
These are described and explained in detail below. Machine type or configuration-related extensions or
deviations are explained in separate texts to prevent confusion.
6.1.2
6.1.2 Conveyor Reference Run
Conveyor Reference Run
The conveyor reference run tests the function of the conveyor belts. This requires the relevant conveyor
belt to be empty i.e. to be free of boards (PCB). Stellt einer der LP-Sensoren eine LP fest so wird dieses
Transportband (so wie auch das Eingabe-Transportband) nicht aktiviert und am Ende des gesamten
Referenzablaufes wird diese LP in das Ausgabeband der Bestückstation transportiert.

Head Axis Reference Run
The C&P6/12 placement heads need to be prepared for the axis reference run.
Sequence:
► Initialize the stepping motor as soon as you have switched on the machine:

► Press START button
This also switches the control voltages on.
► Preparing the star axis reference run
The following steps are performed:
– Upwards movement of Z-axis to top end stopper.
– Downwards movement to Z position (30 digits) with reduced force for free star movement.
► Star axis reference run
The following steps are performed in sequence:
– In the first reference run, the star axis performs a commutation point search for the 3-phase system
of the drive.
– The star axis positions itself at the axis zero pulse.

▪ The valve positioning drives have positioned the drive
ball bearings in the valve plunger so that star rotation
without malfunction is possible.

– The star axis loads the zero point correction value.
– The star axis positions itself at counter status 0. Segment 1 is now in the star pickup/placement
position.
► Z-axis reference point run
As the Z-axis does not have a zero pulse, the Z-axis end stopper is used for this "zero pulse position".
The zero point correction (ZPC) is determined during each reference run.
– The Z-axis moves again to the top end stopper and then positions itself to the standard value of 5
digits. Subsequently:
– The star axis positions to 6250 digits (6.25°).
– The Z-axis moves down again to the end stopper, transmits the Z-axis position and moves back to
the 5 digit position.
– The star axis positions to 6750 digits (6.75°).
– The Z-axis moves up again to the end stopper, transmits the Z-axis position and moves back to
the 5 digit position.
– The star axis positions to -6250 digits (-6.25°).
– The Z-axis moves down again to the end stopper, transmits the Z-axis position and moves back to
the 5 digit position.
– The star axis positions to -6750 digits (-6.75°).
– The Z-axis moves up again to the end stopper, transmits the Z-axis position and moves back to
the 5 digit position.
► The zero point correction value is calculated from the 4 Z-axis positions, is transmitted to the axis
controller and is used until the machine is switched off.
– The star axis is moved back to the 0 position (segment 1 down).
This automatic zero point correction ensures that the segment ball bearing is in the optimum position
for the circular guide.
► The head axis reference run is now finished.

6.1.3.2 Gantry Axis Reference Run
Gantry Axis Reference Run
The first reference run also includes the commutation point search for the 3-phase drive of the gantry
axes.
Sequence:
Initializing the 3-phase drive system and the position measuring system of the gantry axes:

function

► DP axis reference run
– The DP station is swiveled in by a CAN bus com-
mand (2).
– The axis controller starts from the 0 position and
continues until the incremental encoder detects a
segment zero pulse.
► – The DP station is swiveled out again by a CAN bus
command (1).
