▪ 2 motor phases are switched to the power supply of the servo amplifier.
▪ The 3-phase AC motor moves to the next suitable magnetic position.
▪ 2 other motor phases are switched to the servo power supply and the axis moves further.
▪ These switching steps are repeated multiple times.
The axis reference run is continued with a reference position search for the position measuring system.

6.2.3 Reference Run at X and Y Axis (A364)
Zero pulse
Description of zero pulse search:
▪ Requirements:
– The commutation point search has been completed.
– The motor is in position control.
1. After the hardware end stop has been reached and the axis has moved in the opposite direction, the
search for a zero pulse is prohibited within a certain distance of the bumper (approx. 25 mm).
2. After moving out of this prohibited area, the search begins. If the zero pulse is found in this area,
further pulses will be searched for in an area of approx. 2.5 mm If only one zero pulse is found, an
end position message is issued and the reference run is completed.
In the event of a fault, multiple zero pulses or no zero pulses may occur in the defined area. In this
case, the axis will stop and an error message with be issued.
3. The axes are now in a defined position. After finding and checking the zero pulse, the zero point
correction is loaded.
4. The reference run for the main axes has now been completed. The vacuum and height reference
runs will begin.

Travel Ranges and Speed Monitoring
6.3.1 Travel Ranges and Speed Monitoring
The travel range of the X and Y axes will be determined during machine calibration.
This means that, during travel range calibration, the axis concerned moves as far as possible towards
the minimum or maximum position, until the set target value is no longer reached by the axis card. It is
then assumed that the hardware limit switch (bumper) has been reached. In a time window of approx.
10 ms, the greatest actual value achieved is taken to calculate the travel range.
To guarantee an appropriate safety gap before the hardware end switch is touched, a certain distance
is deducted from the set travel range. This enables the axis to brake in time, even when errors occur.

The X axis moves to the left and right bumper and measures their positions with a safety distance of 2.0
mm. The SW also deducts a value of 0.5 mm from the maximum or minimum travel range.
The Y axis moves to its minimum position (gantry 1/2) or to its maximum position (gantry 3/4).
The position opposite is then calculated.

▪ 1 - 4 = gantry 1 to 4
The end of the X axis travel range is + or - 0.5 mm before
the software limit switch, which is 1.5 mm before the
bumper. A safety distance of 2.0 mm to the bumper is
adequate, if the X axis moves into this area with
excessive speed.
The end of the Y axis travel range is + or - 2.0 mm before
the software limit switch. The Y axis travel range for a
particular placement area is monitored in one direction by
the software limit switch and a bumper. In the other
direction, there is a permanent exchange of
communication between the axes and their positions, via
the SPI Bus (see description of the anticrash function).

1. The minimum safety distance between the gantries,
during placement: minimum 4 mm.
Depending on the placement mode (i-placement or
alternating), the gantries will operate in one placement
area fully independently. This means that one gantry
does not need to know the position of the other one.

6.3.2 PCB Boards on the Gantry
The printed circuit boards which are described in this chapter are basically identical on each gantry and
do not depend on the head configuration. The gantry identification settings and the CAN bus terminating
resistance settings are defined at the DIP switch on the head interface.
