Help Program / Alarm

[kperk12345]

It's an Okuma OSP-E100L control

code:
G0 X20 Z20
G50 S900
T0202 G96 S200 M3 M8
X3.8 Z.1
Z-.2
G1 X3.7614 Z-3151 F.02

This works.

If i change the G50 value to S350 i get this alarm:

Spindle Revolution over A side 3E8


any idea why?

Thanks ahead of time....

Only my guess, I think right now machine is on the high gear and I don't think you can go below 500rpm. Keep try to play with the RPM....and it is what I'm guessing then witch machine to lower gear.

Try these changes: (comments inserted for clarity)
G90 (Absolute positioning)
G0 X20 Z20 (Rapid to soft limits)
G50 S350 (Set maximum spindle speed)
G95 (Set feed in IPR)
G97 S=3.82*200/3.8 T0202 M3 (Set starting spindle RPM to match initial X position, select Tool 2)
G00 X3.8 Z.1 M8 (Rapid to initial X,Z position, coolant ON)
G96 S200 (Set CSS mode)
G00 Z-.2
G1 X3.7614 Z-3151 F.02
...
G97 S=3.82*200/3.7614 (last X feed pos)
G00 X20 Z20 M9

This will keep the spindle from wild RPM changes (in G96 mode) when rapid traversing the X axis.

maybe another guess, but our Okuma gets either a M41 or M42 with each tool. (Gear selection)
