Variable texts
There are various ways of defining variable text:
● Date and time
● Quantity
● Numbers
● Text
Mirror writing
You can engrave the text mirrored on the workpiece.
438
For example, you can engrave the time and date of manufacture on a workpiece. The
values for date and time are read from the NCK.
Using the workpiece variables you can assign a consecutive number to the workpieces.
You can define the format (number of digits, leading zeroes).
The place holder (#) is used to format the number of digits at which the workpiece counts
output will begin.
If you do not want to output a count of 1 for the first workpiece, you can specify an
additive value (e.g., <#,$AC_ACTUAL_PARTS + 100>). The workpiece count output is
then incremented by this value (e. g. 101, 102, 103,...).
When outputting number (e. g. measurement results), you can select the output format
(digits either side of the point) of the number to be engraved.
Instead of entering a fixed text in the engraving text field, you can specify the text to be
engraved via a text variable (e. g., _VAR_TEXT="ABC123").
