Help with Okuma HMC auto pallet change

[betts]

Details: Okuma Space Center MA-400HA with OSP E100M control. Two pallets.

 

First let me say Okuma and I have never been buddies, so I am a little weak in that area. We are trying to find out how to get the program to run continuous, obviously once the "load pallet" is ready and that button pushed.

 

We have only been able to get the machine to respond to M60, can't specify which table. Not a huge deal but on all our Fanuc controls we block skip the pallet change so once the program is proven all the operator has to do is load and hit the set-up button and the machine runs continuous.

 

We are currently hitting cycle start every time to keep it running. We inherited the machine used from a sister company but as far as I can tell it isn't screwed up.

 

Any Okuma guys that can offer help?

[MBlair]

If there is an M30 at the end of the program try replacing it with an M99.

[betts]

I should have stated that more clearly. When I said we block skip, we block skip the M30 for M99 on the Fanuc controls. On the Okuma it won't read M99.

 

The applications guy suggested a "GOTO N01" before the M02 and putting the N01 in the beginning. However the problem seems to be we are runnign off an internal card for memory and not the control memory.

 

Do we need to run all programs as a sub and run from the memory?

[Craig-B]

This is how I do it, You have to use the schedule program, and load it into memory with the .SDF extension. Then select the schedule program and stat the run. Then you can just use the pallet ready, and it will change for you. If you want to run something different, add an new schedule program or edit the current.

(PALLET SCHEDULE.SDF)

NSTART

(PALLET #1 PROG. 1234)

PSELECT MD1:1234.MIN

(PALLET #2 PROG. 5678)

PSELECT MD1:5678.MIN

GOTO NSTART

here how you ca do this on an okuma

 

PS the space between each value is very important to get it to work

 

program start

 

vc1=1 (user variable for part count)

NA1 (line to start machining)

***place G-code here***

vc1=vc1+1 (increase part count +1 or the quantity of part produced in a run)

 

if [vc1 eq **insert part required here*** ] NA2 (as soon as the part counter equals the designated value the program will jump to the N2 line)

goto NA1

NA2

m02

Craig,

So with this config. you are posting what runs on pallet-1 as a separate prg. from what runs on pallet-2, correct? Didn't think of that. We have just the one Okuma and many Fanuc controls so I let my brain get stuck I guess.

Use a library file..and user defined M-codes

 

M201 to check if in, or call in pallet1,M202 same for pallet#2

Also looks at the PART LOADED button at the front

 

M205 in place of M9 when using thru-coolant

 

Execution is done by the M-code...either MDI or in the program

 

-Create a file "MA400HA.LIB"

place in it

and then register that LIB file

and then define the M-code macro to the correct call statement ie

M201 is to use OPAL1

M202 is to use OPAL2

M203 is to use ONOT (empty the spindle)

M204 is to use OWARM

M205 is to use OM50O (coolant,spindle, all off,timed air blow, all off)

 

PS. size for the LIBrary file when registering in the control should be just larger than the file byte size

or

 

For pallet 1

 

OPAL1

IF [VPLNO EQ 1] NRTS

M60

MSG (PALLET CHANGE IF CORRECT PALLET PROGRAM WILL CONTINUE)

For Pallet 2

 

OPAL2

IF [VPLNO EQ 2] NRTS

Or just use the varable in the program VPLNO
