KMX CNC Retrofit Safety, Programming, Operating & Care Manual
When the Auxiliary Function option is installed and active, the ProtoTRAK KMX
CNC can control four different auxiliary functions. You can select whether to
activate or deactivate these functions at the beginning or end of each event.
If Auxiliary Functions are selected on the program header, the system will
prompt for AUX BEG and AUX END in each event.
When running programs with Auxiliary functions, the ACCESSORY hard key on
the front panel must have the correct status. If you want the program to
automatically turn the Auxiliary functions on and off, press and hold the
ACCESSORY key until the status line reads ACC AUTO. Press again to turn off.

Indexer
Activates an electronic signal at the end of this event. See note
below.
4
Spindle
Turns off the spindle at the end of this event. Note, the spindle
automatically turns off for each tool change
–
it is not
necessary to program a spindle off.
Coolant/Air on and off is automatically programmed for tool changes. If you
want the air or coolant pump on while cutting the entire part, you need only
program the Aux begin in the first event and Aux end in the last event. The
coolant pump or air solenoid will turn on at the beginning of the programmed
event and will turn off during tool changes.
The Indexer function is designed to operate with a standard indexer.
Programming an Aux 3 at the beginning or end of an event will cause the
ProtoTRAK KMX CNC to stop machining at the beginning or end of the event and
wait for a signal from the indexer. The signal notifies the CNC that the indexer
has finished its programmed move. The CNC will then automatically resume the
program. Make sure your tool is clear of the workpiece before commanding an
index. If need be, add an Aux 3 to the end of a position event.
