5.1.10 RAPID TRAVERSE RATE OVERRIDE SWITCH
This is used to adjust the traverse rate by FO, 25,
50 and 100Yo. rate is the rapid traverse rate set by
parameter #6280 to 6284.
The switch is effective both in automatic operation
including GOO command and in manual operation
(RAPID mode). FO is set by parameter #6231.
5.1.10.1 RAPID FEED OVERRIDE
SWITCH 2
(1) In the conventional function, override of the
four steps of
and can be
commanded against the rapid feedrate.
This function is now expanded to allow override of
the six steps of
25%, FO , and ”
(2) The and feedrates are the feedrates
given by the parameter (#6466, #6467).
5.1.11 FEEDRATE OVERRIDE SWITCH
In the automatic operation mode ( TAPE, MEM,
MDI) , this switch is used to adjust the feedrate
by 10% from O to 200% of the programmed feedrate
specified with an F function at whatever position
the switch may be set.
Feed during tapping by
G74 follows F command. Where OVERRIDE
CANCEL switch is set
the be moved
at the programmed feedrate by F code regardless
of switch setting.

5.1.12 JOG FEEDRATE OVERRIDE SWITCH
1. This option permits overrides in 21 steps of
10% per step within a range of O to 200% in relation
to the jog feedrate.
2. This switch also serves as the “FEEDRATE
OVERRIDE” switch. When the JOG mode is selected.
the Feedrate Override switch becomes the Jog
Override switch.

3, Use this function as follows.
Although the Jog Feedrate switch can be switched
over in a maximum of 32 steps, this is limited
the three steps of LOW - MEDIUM - HIGH and the
intermediate speeds are compensated for with the
FEEDRATE fUnCtion.
5.1.13 FEEDRATE OVERRIDE CANCEL SWITCH
Turning on the OVERRIDE CANCEL switch pre-
vents the function of FEEDRATE OVERRIDE switch.
5.1.14 SPINDLE SPEED OVERRIDE
1. With this switch, the current spindle speed
can be changed to an override speed which
is set at 10% intervals between
50 and
of the current spindle speed.
2. During the tapping cycle by G84 and G74,
the spindle speed may selectively be made
independent of this switch, remaining at the
speed set by S code. This selection is
made with the parameter

Overview
The conventional function that allows to 120%
override against the S command is expanded to
allow override of 10% to 200%.
