DC Absolute coordinate;
approach position
directly(for rotary
axis, spindle)
DEF Definition instruction

FRCM Modal feedrate for
chamfer/rounding
FXS Travel to fixed stop
axis

Value assignments Information
Only specified The call of the machining cycles
values requires a separate block; the
appropriate transfer parameters
must be loaded with values.
Special cycle calls are also
possible with an additional
MCALL or CALL.
- 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
0, >0 In case FRC=0: Feedrate Fwill
act
0, >0 In case FRCM=0: Feedrate
Fwill act
Axis:
=1: select
=0: Deselection
