2.4.2 FEEDRATE (F-FUNCTION) (Cent’d)
F commands for linear interpolations involving
motions in simultaneously controlled three axial
directions specify feedrates also in the direction
tangential to the motion path.
EXAMPLE
With GO1 . Y.. . . F400 ;
F = 400 = fX2 + fY2 +

2.4
F commands for linear interpolations involving
motions in simultaneously controlled four axial
directions specify feedrates also in the direction
tangential to the motion path.
F = + fy2 + +
Notes :
. If FO is programmed, it is regarded as a data
error. (alarm code “030)
. Do not program F commands with minus numerals,
otherwise correct operation is not guaranteed.
EXAMPLE
F-250 ; . . . . . . . . wrong
2.4.3 FEEDRATE 1/1 O
The feedrate programmed by F commands can be
converted to 1 value with a parameter set-
ting as follows.
. When parameter #6020 or is set to “ “
the feedrates range becomes as shown below.

. When parameter #6020 DO or is set to “O, ”
the feedrate range returns to normal.
2.4.4 F 1-DIGIT PROGRAMMING
(1) Specification of a value to 9 that follows
F selects the corresponding preset feedrate.
(2) Set the feedrate of each of to F9 to the
setting number shown in Table 2.15 (a).
(3) By operating the manual pulse generator
w h e n switch is on, the feedrate of -
digit command currently specified may be in-
creased or decreased.
Set the increment or de-
crement value per pulse multiply) to the
parameters listed in Table 2.15 (b).
As a result of this operation, the contents of the
setting number of the F1-digit feedrate are
changed.
(4) Upper Limit of Feedrate
Set the maximum feedrate of designation
to the following parameter. If a value greater
than the usual maximum feedrate (the contents
of #6228) is set, it is governed by the contents
of #6228.
