S S/ FUNCTIONS
With the S function is programmed the spindle revolutions.
Basing on the programmed number if the machine is equipped with more rotation ranges,
the right one is automatically selected and inserted (M40).
During the work cycles, the CN keep under constant control the current absorption
percentage of the spindle motor.
This percentage is visible on the screen. If the absorption percentage is over the 98% for
an equal time to the one imposed in spindle axis configuration, the CN reduce the work
speed of 30% on the one programmed. If the absorption doesn't reduce of 98% the CN stop
the machine and an error appear.
To keep under control an absorption value less than 98% it is sufficient to program: S
(revolutions numb)/(absorption percentage).
Example: S2000/15 = the spindle speed is 2000 rpm, the reduce speed mechanism will
be activated if the absorption percentage exceed the 15% for an equal time to the one
imposed in axis spindle configuration.
