Test the Y-axis limit:
Hold down the down arrow key to move the YZ car in the negative Y direction.
The YZ car should move toward the gantry side plate until it encounters the limit switch target where it
will stop abruptly. Once the YZ car stops, release the arrow key.
Click on the Zero Axis button on the keypad. Select the Y checkbox and click the ZERO button. Notice
that the Y value changes to 0.000 in the position window.
Move the Y-axis off the proximity target using the up arrow key
Check Movement Distance
This step will help find the total available movement area on the X- and Y-axes. This information will
make sure the target and physical stop locations are correct and help with table placement.
The tool should now be near the XY zero location. The X- and Y-axes should have been zeroed at the
proximity target locations during the previous step.
Make sure that neither proximity switch is triggered as this will prevent proper function.
Test X-Axis Distance
Hold down the right arrow key to move gantry in the positive X direction. The gantry will move down
the rails until it encounters the high X target. Release right arrow key when gantry stops.
Look at the red position window to check the X value. This is the total available X movement distance.
This value should be at least 1” larger than the nominal X movement distance. Record this value.
The X-axis typically has extra movement available at this end for use with the Automatic Tool Changer
option. For example a 96-48 table might have an X movement distance of 102.824”.
Move the X-axis off the proximity target using the left arrow key.
Test Y-Axis Distance
Hold down the up arrow key to move the YZ car in the positive Y direction. The YZ car will move
across the gantry until it encounters the high Y target. Release the up arrow key after the YZ stops.
Check the Y value in the red position window. This is the total available Y movement distance. This
value should be at least 1” larger than the nominal Y movement distance. For example, a 96-48 table
might have a total Y movement of 49.427”.
Test Z Zero Function
Clip the Z zero alligator clip to the Z zero plate.
Check the software red positon window for Input 1 light.
Disconnect the alligator clip from the Z zero plate. The Input 1 light should go out.
Proximity Switch Targets
The proximity switch targets are metal bolts that the inductance based limit switches will sense. The
limit switches should be set up to pass just over the target about 1/4” (5mm) before the movement
axis reaches its hard stop. When the software receives this input it will stop the tool so that position is
not lost.
