Setting the display of resolution, time and date
Use the display screen to specify the display reso-
lution of linear and angular values, and to format
the display of time, date and angles.
Click the Tools/Options/Display menu item to dis-
play the Display screen.
Specifying display resolution
Enter the display resolutions for linear and angu-
lar values into the appropriate Display Resolution
fields. Metric values are expressed in millimeters.
Display resolutions that exceed the resolution of
the input encoders result in unnecessary zeros at
the right of the displayed value. Display resolu-
tions less than the resolution of input encoders result in the display of rounded values.
Formatting time, date and angles
Format the display of time, date and angles by clicking the desired radio button.
Displaying the distance to target surfaces for CNC moves
Normally, the DRO displays the current input sensor position. Checking the Display distance to target...
box changes the DRO to display the distance to the next CNC target while running a program. This can be
useful when debugging a program.
The distance decreases during CNC moves until the continuation zone
around the CNC target point is reached. At that time, the DRO displays
the current position until the measurement at the target is complete.
When the measurement is complete, the DRO changes to display the
distance to the next CNC target again. When the program is completed
or halted, the DRO displays the current position until the next program
execution begins.
Showing the last edge position in the DRO
Check the Show last edge... box to show the position of the last edge
detected by the optical edge detection system in the DRO numeric read-
out.
