Calibrating the Anticrash Board

Test setup of anticrash board

► Connect the digital multimeter to the anticrash board

TP 0 (0V) and TP 1 (signal).

► Push the two gantries together.

► Use the adjustment screw to set the voltage on the

distance sensor to 6V - +/- 0.1 V.

► Push the two gantries to a distance of 100 mm.

(elastomeric spring up to countersurface).

► The voltage should be approx. 2V.

Test setup of anticrash board

► Connect the digital multimeter to the anticrash board

at pin TP2 (signal) and at pin TP0 (0V).

► Push the two gantries together.

► Use the potentiometer R82 to set the voltage to 0V-

+/- 0.05 V.

► Push the two gantries together, to a distance of 100

mm +/- 1 mm.

► Use the potentiometer R92 to set the voltage to 0V-

+/- 0.05 V.

► Check the 0V setting again.

► If the value deviates, you will need to calibrate again.

Checking the Distance Sensor Function

Preparation

► Perform a complete reference run.

Test for placement area 1

► Fasten a sheet of paper to the center of the machine in placement area 1, level with the distance

sensor.

SITEST:

► Select "Gantry" ==> "Choose gantry" ==>

"Axis functions" ==> "Y axis" ==> "Position axis"

==> "Edit values and accept for the target position = 1 300.000 digits".

► Press the START button.

► The axis will stop at the obstacle. The distance sensor has triggered.

► Press the EMERGENCY STOP button and remove the obstacle.

► Press the RESET button on the anticrash board.

► Release the EMERGENCY STOP button and press the START button.

► Perform a reference run for the gantry.

► Perform a test for placement area 2 following the same procedure.

NOTICE

Select "gantry3" for placement area 2. Edit and accept a target position of 600.000 digits

Checking the Function of the Anticrash Board

Preparation

► Perform a complete reference run.

Testing the Proximity Switch on the Gantry

► Press the EMERGENCY STOP button.

► Unplug the relevant connector from the proximity switch.

► Release the EMERGENCY STOP button.

► Press the START button.

► Select the corresponding X or Y axis for the disconnected proximity switch.

SITEST:

► Select "Gantry" ==> "Choose gantry" ==> "Axis functions" ==> "Choose axis"

==> "Dynamic axis behavior" ==> "Set the travel path 9

(200.000 digits)".

▪ The anticrash board will trigger.

▪ The selected axis will brake in the relevant direction.

▪ As the anticrash board has triggered, you will see the following error message here:

"Gantry distance insufficient. Protective circuit reacted".

► Press the EMERGENCY STOP button.

► Reconnect the relevant proximity switch.

► Press the RESET button on the anticrash board.

► Release the EMERGENCY STOP button.

► Select "Cancel" and press the START button.

► The axis is now back in its normal state.

5.1.6 Mechanical Adjustment of the Incremental Encoder

Mechanical Adjustment of the Incremental Encoder

The incremental encoders (read units) on the X and Y axis are adjusted exactly to the position of the

incremental scale. The two limit marks on the incremental encoder show where the top/bottom positions

of the scale should be. The encoder is also mechanically set to a distance of 0.4 mm +/- 0.1 mm to the

incremental scale.

After this adjustment of the incremental encoder you have to check the zero pulse and track signals.

Correct installation should ensure correct count and zero pulse signals. For troubleshooting purposes

(error analysis and fixing), you will need to measures these signals with the oscilloscope. (See service

manual.)
