Travel Ranges and Speed Monitoring at the X3 (A363)
The travel range of the X and Y axes will be determined automatically with the SITEST program. This
means that during calibration of the travel range of gantry 3 at placement area 2, the respective axis
moves as far as possible into its minimum and maximum position, until both proximity switches switch.
A safety gap before the hardware limit switch is calculated for each individual machine (see travel ranges
HF). For the Y axis of placement area 1, gantry 1 moves just to the minimum position and gantry 4 to
the maximum position.
Travel range X and Y axes of X3 machine
1. The calculation of travel ranges for the X axes at gantries 1/3/4 and of the Y axis at gantry 3 follows
the same procedure as the calculation for HF machines.
2. The travel range for the Y axes are calculated partly. This means that the Y axis of gantry 1 moves
into the minimum position and the Y axis of gantry 4 moves into the maximum position. As a result:
maximum position gantry 1 = maximum position gantry 4 - 480mm (gantry width) - 20mm safety
space. (In X4 machines, the travel ranges are set accordingly for gantry 2) Minimum position
gantry 4 = minimum position gantry 1 + 480 mm (gantry width) + 20 mm safety distance. (In X4 ma-
chines, the travel ranges are set accordingly for gantry 3)
3. Safety space approx. 20mm

Setting the Proximity Switch
On each axis are two proximity switches installed, which need a distance about 0.4 mm to the metal ac-
tuator. The metal actuator are installed on the left and right side from the incremental scale. Adjust cor-
rectly the distance with a distance gauge of 0.4 mm. After this adjustment calibrate the travel range for
the respective axis with the SITEST program.

The travel range of the X and Y axes will be determined automatically with the SITEST program.
This means that, during travel range calibration, the axis concerned moves as far as possible towards
the minimum or maximum position, until the set axis card target value is no longer reached. It is then
assumed that the hardware limit switch (buffer) 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.
Travel range for X and Y axes (D4 and X4 shown here)
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 buff-
er. A safety distance of 2.0 mm to the buffer 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 buffer. In the other direc-
tion, there is a permanent exchange of communication
between the axes and their positions, via the SPI Bus
(see description of the anticrash function).
Travel range for X and Y axes (D4 and X4 shown here)
1. During travel range calibration, the X axis moves as
far as possible towards the minimum or maximum po-
sition, until it touches the bumper.
The travel range is calculated, taking into account a
safety distance.
2. In placement areas 1 and 2, gantry 1/2 moves to the
minimum position and gantry 4/3 to the maximum po-
sition, for calculation of the Y axis travel range .
3. Safety distance between the gantries during place-
ment: minimum 4mm.
