M48 must be placed at the beginning of the program (or section of program) that is run for the current pallet. This
will check each time that a program is run, that the program matches the pallet. For example:
Oxxxx (Users program)
M48
;
; (Users part program for pallet 1)
;
M30
Oxxxx (Users program)
M48
;
; (Users part program for pallet 2)
;
M30
An alarm will be generated, “A (or B) not in Position”, if the pallet in the machine is not the one associated with the
part program. If this alarm is generated, verify the correct program is running for the loaded pallet.
Important: Verify that the rotary table on pallet one is plugged into “Connector 1”, and that the rotary table on
pallet two is plugged into “Connector 2”.
Sample Programs
Example #1
A basic pallet change program that loads the next scheduled pallet and runs the parts program. The following is a
sample of the PST, which indicates that pallet #1 is loaded and pallet #2 is scheduled. Pallet #2 will be loaded next
(see column 2, “Load Order”) and program O06012 will be used to cut parts on that pallet (see column 5, “Program
Number”). The program comment is captured from the program.

Set current pallet status to 12 actual string defined by operator. In this case, status
number 12 is defined as “Last Pallet”.
M99
(Return from subroutine.)
Description: The first loop through program O00001 will load pallet #2 (M50) and run program O06012 (G188
selects program from PST for pallet #2). The PST will then resemble Sample Table 2. The asterisk for pallet #2 in
the “Load Order” column indicates that this pallet is in the mill.
