I have an Okuma Howa Milac 4H that is working fine other than the pallet changer. i can mannually shuttle them in and out with the controls over at the front of the machine but I can not get it to do it in a program. When I run the prgram for a pallet change it move to change posistion then just sits there waiting on someting. Does any one have a sample program they can send me for a pallet change so I can see if I am missing someting in my program?

Here are what was in the machine when I got it.

You usually have to press a pallet select button (L or R pallet) to start a pallet change cycle. The machine could be waiting for the pallet door open signal, table unclamp, pallet change program pos = pallet change parameter pos. Also are pallet counters correct, does the control know where each pallet is ?

in single block, which line of the program does it stop on ?

Here is what I can tell you. the machine stops at the m62 code. it moves in to change position and then stops waiting on the next move. I dont know how to tell what pallet it is looking at to tell if it is in the right position. it has a fanuc 11m control on it.

I worked an Okuma MX40 horizontal with pallets.

With it there is an additional button to press before a pallet can cycle in AUTO mode

Is there a button to acknowedge that the standby pallet has had a part loaded onto it, and is ready to be shuttled into the machine ?
ie "WORK LOAD FINISHED" or something similar.

What does the manual say for the M-codes ( M61/62/63 )

I have a Okuma Howa 40H. To change pallets in MDI mode we enter a M60 <EOB> and then press the pallet standby button at the loading station. In programs we generally use a master program and subprograms for each pallet with the main program handling the pallet changes. The 2 programs you posted look like the subprograms.

Here is our main program:

%O0001
(USE TO RUN TWO PROGRAMS);
N005 M98 P9136 (PALLET A);
N010 M60;
N015 M98 P9137 (PALLET B);
N020 M60;
N025 M99;

On our machine M00 is Program Stop and M61-M86 are not defined. Of course as it is a different machine you may have options we don't have. Our machine uses a Fanuc 16M control
