Spindle Override – The Spindle Override Slider and RPM 100% buon allow you to override the
commanded spindle speed by percentages ranging from 1 percent to 150 percent. The RPM 100%
buon returns the override to 100 percent of the commanded value or no override. The spindle
must be running for these controls to have a noceable eect. If you override the spindle when it is
stopped, the speed is overridden the next me spindle starts. The override doesn’t drive the spindle
past its maximum speed. The Spindle Override seng is ignored during spindle-synchronized moves
or any me M48 (disable feed and speed overrides) is in eect.
Feedrate Override – The Feedrate Override Slider and Feed 100% buon work similarly to the Spindle
Override controls. They aect the commanded feedrate by a percentage ranging from 1 percent
to 150 percent. The feedrate override works for MDI, jogging, and G-code program G01/G02/G03
moves. The override has no eect on G00 (rapid) moves. The Feedrate Override seng is ignored
during spindle-synchronized moves or any me M48 (disable feed and speed overrides) is in eect.
Maxvel Override – The Maxvel Override and Maxvel 100% buon work similarly to the Feedrate
Override controls, except that these controls aect both G00 and G01 moves. They clamp the mill
velocity to a percentage of the maximum velocity. The Maxvel Override slider can be very useful
when running a G-code program for the rst me. You can use it to stop the mill by sliding it down
to 0% and verifying the Distance to Go (DTG) and X/Y/Z/A DROs look appropriate before connuing
(for more informaon, refer to Posion Status Group later in this chapter). The Maxvel Override
is a safety feature, and as such is not inhibited during spindle-synchronized moves or with M48.
Make sure that Maxvel is at a value that allows the mill to achieve the programmed feed rate during
spindle-synchronized moves or the move may fail to produce the intended results.
6.2.2 Position Status Group
The buons, labels, and DROs of the Posion
Status Group pertain to mill posion, acve
G-code modalies, and feed/speed sengs
(see Figure 6.3). These controls may be used
at any me before or aer running a G-code
program or MDI move. They are unavailable
for operator input while mill is moving.
Axes Work Oset DRO – Displays the current
mill posion expressed in the currently acve
work oset coordinate system (G54, G55, etc.)
for the X-, Y-, Z-, and A-axis.
When the mill is at rest, these DROs are also
operator entry elds. Change the current
work oset posion by clicking in the DRO
eld, which illuminates. Type a number, for
example 4.0, and click the Enter key. Click the
Esc key to return to the original value.
