11.3 DATUM Shift with Datum

Tables (Cycle 7, DIN/ISO: G53)
Effect
Datum tables are used for:
Frequently recurring machining sequences at various locations on
the workpiece
Frequent use of the same datum shift
Within a program, you can either program datum points directly in the
cycle definition or call them from a datum table.
Reset
Call a datum shift to the coordinates
X=0; Y=0 etc. from the datum table.
Execute a datum shift to the coordinates X=0, Y=0 etc. directly with
a cycle definition:
Use the TRANS DATUM RESET function.
Graphics
If you program a new BLK FORM after a datum shift, you can use
MP 7310 to determine whether the BLK FORM is referenced to the
current datum or to the original datum. Referencing a new BLK FORM
to the current datum enables you to display each part in a program in
which several pallets are machined.
Status displays
In the additional status display, the following data from the datum
table are shown:
Name and path of the active datum table
Active datum number
Comment from the DOC column of the active datum number
