2.4 TRAVERSE AND FEED FUNCTIONS
2.4.1 RAPID TRAVERSE RATE
2. 4.1.1 RAPID TRAVERSE RATE
The rapid traverse motion is used for the motion
for the Positioning and for the motion for
the Manual Rapid Traverse (RAPID) . The trav-
erse rates differ among the axes since they are
dependent on the machine specification and are
determined by the machine tool builders. The
rapid traverse rates determined by the machine
are set by parameters in advance for individual
axes.
When the tool is moved in rapid traverse
in two or three axial directions simultaneously ,
motions in these axial directions are independent
of each other, and
end points are reached at
different times among these motions. Therefore,
motion paths are normally not straight.
For override rapid traverse rates , Fo, 25%, 50%
and 100% of the basic rapid traverse rates , are
available.
Fo is a constant feed rate set by a
parameter ( #6231) .
2. 4.1.2 SETTING RANGE OF RAPID TRAVERSE
R A T E
For each axis, rapid traverse rates can be set
at some suitable multiple of O. 001
(or deg /
min ) .
The maximum programmable rapid traverse rate is
30,000 However, respective machine tools
have their own optimum rapid traverse rates. Refer to
the manual provided by the machine tool builder.
2.4.2 FEEDRATE (F-FUNCTION)
With five digits following an address character F,
tool feedrates per minute (mm /rein) are program-
med.

The maximum feedrate is subject to the perform-
ance of the servo system and the machine system.
When the maximum feedrate set by the servo or
machine system is below the maximum program-
mable feedrate given above, the former is set by
a parameter ( #6228) , and whenever feedrates
the set maximum limit are commanded, the
feedrate is clamped at the set maximum value.
F commands for linear and circular interpolations
involving motions in simultaneously controlled
two axial directions specify feedrates in the direc-
tion tangential to the motion path.
