Troubleshooting MO3/M04 operation
I have a 1983 Kitamura mycenter 3 with Fanuc 6m controller. I can issue a spindle speed and m03 or m04 command in MDI and machine responds. RPM gage reads whatever S**** I entered. However when I right a test code with a few moves etc it comes to the S500 M03 line, spindle turns on and program stops like it's not receiving speed obtained signal. I can hit reset, spindle stops and rest of program continues on thru. Anyone have ideas on fixing this...or even a parameter to change to eliminate the speed verify?

put up you bit of test code that is not working
.... it may not be that line that is at fault
Re: Troubleshooting MO3/M04 operation
Superman's suggestion is a good one. In full auto the control reads in several lines ... so the issues may well be further down the code.
Another suggestion ... did you try single block instead of full auto? ... does it go any further in single block?
Hope this helps ...

Hi,
Remove the G02 in all the lines or add a R-value ( I / J) in these G02 lines.
Is there no alarm ?

Another suggestion:
G28 X0 Y0 Z0 must be commanded in G91 mode. Change to G90 thereafter.
For safety reasons, it is better to home Z first, followed by XY home::
G91 G28 Z0;
G28 X0 Y0;;
G90;
