9.4 Spindle data
The speed limits set for the spindles that must not be under- or overshot,
are displayed in the "Spindles" window. You can limit the spindle speeds in
the fields "Minimum" and "Maximum" within the limit values defined in the
relevant machine data.
In the field "Spindle speed limitation for G96", the programmed spindle
speed limitation at constant cutting speed is displayed together with the
permanently active limitations. This speed limitation, for example, prevents
the spindle from accelerating to the max. spindle speed of the current gear
stage (G96) when performing tapping operations or machining very small
diameters.
