6.2.2.1 Anticrash Function for the A364

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.

6.2.2.2

6.2.2.2 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 ).

6.2.2.3 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.

6.2.2.4

6.2.2.4 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.

PCB Boards on the Gantry

The boards on the gantry, as described below, are basically identical and do not depend on the head

configuration of D1, D2 and D4 machines. The CAN bus terminating resistor is fixed onto the gantry head

distributor.
