1.1 Fundamentals of programming
Information
It is also possible to specify the
dimensions for the end point of a
rotary axis with DC(...)
irrespective of G90/G91; also
applies to spindle positioning
Defining a local user variable of
the type
BOOL, CHAR, INT, REAL,
directly at the beginning of the
program
Starting with configured axis
acceleration;
starting with sudden
acceleration;
run-in path specified, if
necessary with axis overload
Braking with configured axis
acceleration.
Braking with sudden
acceleration,
specification of run-out path,
with rounding
When FRC=0, feedrate F will act For the unit, see F and
When FRCM=0, feedrate F will
act
A GoTo operation is performed
to a block marked by a label; the
jump destination is in the
direction of the program start.
A GoTo operation is performed
to a block marked by a label; the
jump destination is in the
direction of the end of the
program.
The dimension can be specified
for the end or center point of a
certain axis irrespective of G90.
