DATUM SHIFT with datum tables (Cycle 7, DIN/ISO: G53) 10.3
Please note while programming:
Danger of collision!
Datums from a datum table are
exclusively
referenced to the current reference point
(preset).
If you are using datum shifts with datum tables, then
use the SEL TABLE function to activate the desired
datum table from the NC program.
If you work without SEL TABLE, then you must
activate the desired datum table before the test
run or the program run. (This applies also to the
programming graphics).
Use the file management to select the desired
table for a test run in the Test run operating
mode: The table receives the status S
Use the file management in the Program run,
single block and Program run, full sequence
operating modes to select the desired table for
program run: The table receives the status M
The coordinate values from datum tables are only
effective with absolute coordinate values.
New lines can only be inserted at the end of the
table.
If you create datum tables, the file name has to start
with a letter.
Cycle parameters
Displacement: Enter the number of the datum from
the datum table or a Q parameter. If you enter a Q
parameter, the TNC activates the datum number
entered in the Q parameter. Input range 0 to 9999
