Unit 7 Datum Shift (FCL 2 function)
Unit 7 Datum Shift is used to define a datum number from the datum
table that you have specified in the program header. Select the datum
number via soft key.
Unit 404 Set Basic Rotation
Unit 404 is used to set any basic rotation. Use this unit primarily to reset
basic rotations that you have specified through probing functions.
Before you use unit 7 you must select in the program head
the datum table in which smarT.NC will apply the datum
numbers (see “Program settings” on page 49.).
Reset datum shift: Define unit 7 with number 0. Ensure that
in line 0 all coordinates are defined as 0.
If you want to define a datum shift by entering coordinates,
use the conversational unit (see “Unit 40 Conversational
Programming” on page 156.).
