SET: Various values, from the
specified element up to: ac-
cording to the number of val-
ues
REP: the same value, from the
specified element up to the
end of the field
0.001 ... 359.999 Specified in degrees; the
thread starting point with G33
will be offset by the specified
value (not applicable for tap-

n =1,
axis identifier: e.g. "SP1" or
"C"
0.0000 ... 359.9999 Specified in degrees; the
spindle stops at the specified

- Special function; filling of the
buffer memory until
STARTFIFO, "Buffer memory
full" or "End of program" is
detected.
- Special function; the buffer
memory is filled at the same
time.
- Special function; the next
block is only decoded if the
block before STOPRE is com-
pleted.

Kinematic transformation
(available only if configured
accordingly)
Disables kinematic transfor-
mation
Activates and defines a cou-

Deactivates a coupled axis
