Palette Change M201/M202 Alarm

Hi

Found a helpful library file on this forum. MX40-HA.zip

M201= call in pallet#1,continue if pallet#1 is current
M202= call in pallet#2,continue if pallet#2 is current
M203= empty tool from spindle
M204= call WARMUP cycle for machine
M205= empty thru tool coolant line with air blow

If i use M201 or M202 when the right palett is "in" the machine, nothing happens and everything is ok

If I use M201 or M202 when the wrong palett is "in" the machine, i got an Alarm :

2207 ALARM-B Expression: factor 512F

Machine MA-600HB 2008/07
OSP-P200M

M203,M204 and M205 works great

Is there somebody who may know what causes this?

Ole H (sorry for bad English....)

This library file was originally designed for a OSP7000 control.
The alarm sounds like that some "expression" in that code does not work on your P200 control
I cannot assist as I no longer have access to an Okuma machine...
What you could do is put sections into a normal program, single step through it, and find the offending code... the following is used to call PALLET 1... RTS changed to M30

Code:

---

OPAL1(PALLET1)
NSTRT(CHECK WHICH PALLET IN MACH)
 IF[VPLTK EQ 2]NCHK2 ( PALLET#2 - IN MACH)
 IF[VPLTK EQ 1]NEND
 GOTO NERR1
NCHK2
 IF[VORD[WKPL] NE 1]NMESS
 M60
 RP=1 M289 ( SET PALLET#1 ) GOTO NEND
NMESS
 VNCOM[1]=1
 MSG (******************************** CHECK NEXT PALLET IS READY AND PRESS WORK LOAD FINISHED ********************************)
NLOOP
 IF[VORD[WKPL] NE 1]NLOOP
 NMSG
 GOTO NSTRT
NERR1
 VNCOM[1]=1
 MSG (ILLEGAL PALLET COND)
 M0
 GOTO NEND
NEND M30

Hi

Thanks for reply and tips

When i put this into a normal program it seems like it stops on the" IF[VORD[WKPL] NE 1]NMESS" line...

NMESS is only a jump destination.... there must be sometime else, a space missing, not liking the WKPL command ( this hold the PALLET number in the machine for a OSP7000)
I don't know, and I am unable to check... sorry

I think this is incorrect
WKPL (I think) is the workload finished button, that it is OK to change pallets.
