Spindle Override – The Spindle Override Slider and RPM 100% buon (see Figure 6.2) 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 overriden when the spindle
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
(e.g., G84 tapping cycle) 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 (see Figure 6.2) 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 (e.g. G84 tapping cycle) moves or any me
M48 (disable feed and speed overrides) is in eect.
Maxvel Override – The Maxvel Override and Maxvel 100% buon (see Figure 6.2) 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 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 percent and verifying the Distance to Go and X/Y/Z/A DROs look appropriate before
connuing. 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 (e.g. G84 tapping) 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 DROs – The X, Y, Z, and A
work oset DROs display the current mill
posion expressed in the currently acve work
oset coordinate system (G54, G55, etc.).
