Feedrate Override Dial [OVERRIDE]
The OVERRIDE dial is used to adjust the axis feedrate.
For example, this dial is used to find the most appropriate
feedrate during the operation of the machine.
When 100% (126 mm/min) is selected, the indicator in the
is lit.
When the dial is set at the 0% (0 mm/min) position, all axis movement stops.
Do not stop axis feed by setting the OVERRIDE dial in the 0% (0 mm/min) position. To
suspend axis feed, press the
(STOP) switch. If axis feed is suspended using the
OVERRIDE dial, an operator cannot recognize how the machine was stopped since no
indication is given and, therefore, such operation should be avoided. If axis feed is
suspended using the
(STOP) switch, the status of the machine can be recognized
since the indicator above the switch is lit.
Furthermore, if the dial is quickly operated repeatedly to suspend axis feed, it could
cause machine damage.
<In the automatic mode>
The programmed feedrate (F code) is adjusted in the range of 0 to 150% in increments of 10%.
An axis will be moved at the programmed feedrate when the setting is 100%.
<In the manual mode>
In manual operation, the axis feedrate can be set in the range of 0 to 1260 mm/min (16 steps) if
the mode selection switch
(JOG) is selected.
The relationship between the OVERRIDE dial setting and actual feedrate is indicated below.
