Okuma OSP Alarm A 1229 - Max. spindle rotation count not specified
Max. spindle rotation count not specified
The allowable maximum spindle speed (G50 S****) was not designated before the spindle rotation command was given for automatic operation. Without the G50 clamp, the control refuses to run the spindle in auto mode.
Common Causes
- Program error: G50 S**** missing before the spindle rotation command
- Program structure lost the G50 setting before automatic operation
Troubleshooting Steps
- 1Read the code number shown with the alarm: code 1 = Allowable maximum spindle speed not designated before spindle rotation command
- 2Read the code: 1 confirms the allowable maximum spindle speed was not designated before the spindle rotation command for automatic operation.
- 3Open the program and find the first spindle rotation command; add a G50 S**** line before it with the allowable maximum spindle speed for the job.
- 4Check subprograms and macros called before the rotation command to ensure they do not clear the G50 setting.
- 5Rerun the program in single block through the first spindle start to confirm the alarm is gone.
