5 Reference Run
5.1 Reference Run (D-Series)
The placement machine reference run guaranties the correct function for placement in the station SW.
This is where the reference runs for the C&P head and for the gantry are described. A separate chapter
describes the reference run for the P&P module, performed parallel to that for the C&P head.
5.1.1 Overview
The reference run is divided into 4 main steps. Module reference runs for the WPC or for a 2nd
placement 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.
5.1.2 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). If one of the PCB sensors detects a board, this conveyor
belt will not be activated and this board will be transported to the output conveyor of the placement
station, at the end of the complete reference run.
5.1.3 Axis Reference Run
5.1.3.1 Head Axis Reference Run
The C&P6/12 placement heads need to be prepared for the axis reference run.
