5.1.3 Travel Ranges and Speed Monitoring
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 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.
The X axis moves to the left and right buffer 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 minim travel path.
The Y axis moves to its minimum position (gantry 1/2) or maximum position (gantry 3/4).
The opposite position is calculated
Travel ranges for X and Y axes (X4I)
(1) to (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 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 ranges for X and Y axes
1. Safety distance between the gantries during place-
ment: minimum 4mm.
Depending on the placement mode (i-placement or alter-
nating), 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.

Anticrash Function for the A364
▪ The anticrash function is no longer provided by the anticrash board but instead by the A364 software
(application 1). This means that the proximity switches used to monitor the travel range and the sen-
sor for monitoring the gantry spacing are no longer required.
▪ Tasks:
– Monitoring the X and Y axis travel ranges
Evaluation of the actual position of the respective axis in the direction of the bumper, based on
the speed.
– Monitoring the distance of both Y axes in a placement area
Evaluation of the actual position of the own gantry and the partner gantry at gantry crash moni-
toring.
– Count error monitoring of the gantry axis
Monitoring incoming count pulses (edge control) over time.

5.1.4.2 Anticrash Monitoring for the A364
Anticrash Monitoring for the A364
The anticrash function is activated after the X/Y axes have been referenced. When the gantry axes are
referenced for the first time, anticrash monitoring is not active, which does not matter, due to the low ref-
erence speed.
After this, the bit is set for the anticrash monitoring function and the actual position for the relevant part-
ner gantry is continuously communicated via the SPI Bus.
The following information is exchanged between the Y axes:
▪ Actual position and speed of the own gantry
▪ Status information (reference state, anticrash monitoring state ).

5.1.4.3 Error "Gantry Crash"
Error "Gantry Crash"
A “gantry crash” error is established by calculating the position difference and speed difference for both
axes. A gantry crash error is signaled via the axis card and the CAN Bus. The servo is released for both
axes and both need to be referenced again.
5.1.4.4
5.1.4.4 Count Error:
Count Error:
If the axis board detects a "fatal count error", the axis concerned will be released and the anticrash func-
tion disabled. The other axis is informed of this in the status information and will also disable the ant-
icrash function. The released axis now needs to be referenced again.
after which the anticrash function will be re-enabled for both axes.
