Gantry Anticrash Function for the A364 Axis Card
214 Service Manual SIPLACE D4
6.2.2.2 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 will not be active, which is not so important, due to the
low reference speed.
After this, the bit is set for the anticrash monitoring function and the actual position for the relevant
partner gantry is continuously communicated via the SPI Bus.
The following information is exchanged between the Y axes:
Actual position of the own gantry
Gantry speed
Status information (reference state, anticrash monitoring state ).
6.2.2.3 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.
6.2.2.4 Count Error:
If the axis board detects a "fatal count error", the axis concerned will be released and the anticrash
function disabled. The other axis is informed of this in the status information and will also disable the
anticrash function. The released axis now needs to be referenced again.
after which the anticrash function will be re-enabled for both axes.

6.2.3 Description of the PCB boards on the Gantry
The boards on the gantry described below are basically identical and do not depend on the head
configuration of D1, D2 and D4 machines (the D3 has a different board here). The CAN bus terminating
resistor is fixed onto the gantry head distributor.
