10.4.2 Spindle speed limitation: G25, G26
Functionality
In the program, you can limit the limit values that would otherwise apply by writing G25 or
G26 and the spindle address S with the speed limit value. At the same time the values in the
setting data are overwritten.
G25 or G26 only need one separate block each. A previously programmed speed S is
maintained.
Programming
G25 S... ; Lower spindle speed limitation
G26 S... ; Upper spindle speed limitation
Information
The outmost limits of the spindle speed are set in machine data. By entering via the operator
panel, setting data for further limitations can be activated.
For the function G96 -constant cutting speed, an additional upper limit (LIMS) can be
programmed/entered.
Programming example
N10 G25 S12 ; Lower spindle speed limitation : 12 rev/min
N20 G26 S700 ; Upper spindle speed limitation : 700 rev/min
