Unit 7 Datum shift (FCL 2 function)
With unit 7, datum shift, you 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
With unit 404 you can 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 47.).
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
Unit” on page 144.).
