Program simulation and execution.
Tool and offset.
Blocks with T and D programming (next tool and offset) are ignored during the retrace
function. Blocks with D programming (change of active tool offset) cancel the retrace
function.
·M· functions.
The behavior of the retrace function when executing M functions depends on how the
machine manufacturer has set it up. When the CNC finds an M function, it can either ignore
it and keep executing blocks in retrace or cancel the "retrace" function. In any case, the
following M functions behave as follows.
• Functions M00 and M01 are always executed; they are sent to the PLC and [CYCLE
START] must be pressed to resume execution in retrace.
• Functions M03 and M04 are always ignored; the CNC does not start the spindle nor does
it change its turning direction.
• While the spindle is running, function M05 cancels the "retrace" function; the CNC does
not stop the spindle. If the spindle was stopped, this function is ignored.
• Functions M19, M41, M42, M43 y M44 cancel the retrace function.
Functions that cancel the retrace function.
Definition. Functions and instructions.
Gear change. M41 M42 M43 M44
Spindle orientation. M19
Effective spindle stop. If the spindle was stopped, this
function does not cancel the retrace function.
M5
Change of work plane. G17 G18 G19 G20
Changing zero offset and fixture offsets, etc.
Functions G53-G59, G159 only cancel the retrace function
if they cancel an active zero offset.

Probing. G100 G101 G102
#SELECT PROBE.
Activate, cancel or modify constant surface speed. G96 G97
"C" axis.
The instruction #CAX OFF only cancels the retrace function
if it cancels an active #CAX.
