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.)

NOTICE
The test is identical for all gantry groups.
NOTICE
To set this distance, use one or more small plastic disks with a total thickness of 0.4 mm.

Checking the Zero Pulse Signal
The zero pulse must be reliably and clearly recognized by the read head. To ensure this, you can check
both the analog and the digital zero pulse. Electronically controlled settings can not be performed on the
incremental length measurement system.

NOTICE
New incremental encoder
Since 2007, machines have been equipped with a new incremental encoder (as in SIPLACE
D4). A larger measuring window allows you to compensate contaminants on the incremental
scale (up to approx. 3.5 mm).
