Spindle
"S" is the identification letter for spindle data. Depending on which
mode of the Constant speed soft key is active, data is entered in:
„ Revolutions per minute (constant speed)
„ Meters per minute (constant cutting speed).
The input range is limited by the maximum spindle speed. You define
the speed limitation in "Set T, S, F", in machine parameters 805/855,
or in DIN programming with the G26 command.
The speed limit remains in effect until a new speed limit value is
programmed.
The speed compensation controller (speed override) allows you to
change the spindle speed (range: 50% to 150%).
The subscript number after the identification letter "S" indicates the
gear range.

„ If you are machining with a constant cutting speed,
MANUALplus calculates the spindle speed from the
position of the tool tip. The smaller the diameter of the
tip, the higher the spindle speed. The maximum spindle
speed, however, is never exceeded.
„ The spindle symbols indicate the direction of spindle
rotation as seen from the point of view of the machinist.
