5.2.6 Zero Offset
Settable zero offset
You can activate one of the 4 settable zero offsets in the called
part program
with G54
to
G57.
The value of the settable zero offset for each axis is the sum of:
•
The coarse offset (ZERO
OFFSET) and
•
the fine offset (ZERO
OFFSET
FINE)
Note:
Input of the values for
G54
to
G57 is described
in
Section
4.5.
Programmable zero offset
Using ''G58" and "G59" you can program an additional zero offset for all existing axes
in
the
called
part
program. Details of how
to
program these zero offsets are
to
be found in the
Programming Guide
(User Documentation for SINUMERIK 805).
The
programmed
zero offsets of a
current
program can be displayed on the
screen
by
selecting ZERO
OFFSETS.
Note:
The values of the ZERO OFFSETS
programmed with
G58
and/or
G59 are cleared
with
program end (M02, M30).
External
zero
offset
The values for the external
zero offset (ZERO OFFSET EXTERN) are transferred from the
interface control (PLC)
to
the NC.
These values can also
be displayed on the
screen
by selecting
ZERO OFFSETS.
