Q: What does Mazak alarm 123 mean?

Mazak alarm 123 is "SP ROT. FLUCT. SETTING ERROR (Alarm No., )". Alarm No. | Cause --- | --- &0000 0001 | When specifying the M code for enabling the spindle speed fluctuation synchronous mode, a spindle that was already in the spindle speed fluctuation synchronous mode in another control path was specified. &0000 0002 | When specifying the M code for enabling the spindle speed fluctuation synchronous mode, the specified spindle or NC axis did not exist. &0000 0004 | When specifying the M code for enabling the spindle speed fluctuation, a spindle whose spindle speed fluctuation was already enabled in another control path was specified. &0000 0008 | When specifying the M code for enabling the spindle speed fluctuation, the specified spindle or NC axis did not exist. &0000 0010 | The spindle whose spindle speed fluctuation is enabled does not match the spindle encoder number or the spindle specified for the constant surface speed control. Error type: Registered Data — program or tool data error. Machine state: Feed hold — feed stopped, machine ready.
