Unit 141 Datum Shift

Unit 141 Datum Shift is used to define a datum shift with the direct input

datum table. You need to have specified the datum table in the program
header.

Define datum shift via the datum table. Enter the datum

number or choose it via the SELECT NUMBER soft key.

If you have selected a datum table, the TNC only uses the
programmed line number until the next time a datum
number is called (unit-wise effective datum shift).

Completely reset datum shift: Press the RESET DATUM
SHIFT soft key. If you only want to reset the datum shift in
specific axes, program the value 0 in the form for the
respective axis.
