program problrm

[m_ghaff2000]

We have center machine with Fanuc OM control
I wrote a program such:

.
.
.
N50 G53 g00 z-10...
N60 M03 s1000
N70 ...

after execution the program all line are executed but the machine stop on spindle rotation line M03 s1000 the spindle rotates but the program dosent go to next line!!! on the spindle drive rotation is indicated 1005 rpm.
I have chck it in MDA mode M03 S1000 spindle rotates but the light on program starts remain on.
I have checked all parameter. is there any diagnostic to show me real spindle rotation?
please help me soon I need help urgently!

thanks

All I can think of quickly is a signal from the spindle drive (speed arrival?) that signals to the PLC/control to proceed. I would need the machine electrical to tell which signal it is.

i think u have G1,G2 or G3 with out feed rate given in one of the blocks after N60, check ur prog very good , and see if u have an alarm
i hope this help
bye

check the dry run switch, and spindle arrival signal.. it probably isnt on..

[m_ghaff2000]

I have checked Spindle arrival signal it is "ON" after a few milisecond after M03 S1000 command.
but the program stop in this line!!?
Thanks

Possibly, M03 is redefined on your machine, using macros?

[Boots]

If your machine can read 3 lines ahead which I think it does, the error may not be on the line it stops on. Could we see more of the program please?

[bmngator]

I think Boots is right. Show us some more of the program.

Thanks all for youe reply

my proram is:

N20 G00 G53 z-1
N30 M03 S1000
N40 G00 X.. Y..
N50 G01 F.. Z...

if I omit line N30 M03 S1000 the program executed normally! without problem and axis go to locations. but with spindle rotation stop on N30!?
Thanks

Possibly, some hardware problem regarding completion of M-code???

If you are working on 0i series control, assign a value of 2 to system variable #3003 before M03, and see what happens.

Does this happen right after a tool change?

[nabil_elbadri]
