9. SPINDLE SPEED FUNCTION
1061
[Classification] Output signal
[Function] This signal indicates that the actual spindle speed is not within a tolerance
to the specified speed.
[Output condition] The signal becomes logical “1” when:
⋅ The actual spindle speed goes out of tolerance to the specified speed.
The signal becomes logical “0” when:
⋅ No alarm condition has been detected for spindle speed fluctuation.
⋅ An alarm condition is cleared by resetting the NC when the signal is
