Editing 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 fields "Minimum" and "Maximum" within the limit values
defined in the relevant machine data.
Spindle speed limitation at constant cutting rate
In field "Spindle speed limitation at 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.
Note
The "Spindle data" softkey only appears if a spindle is configured.
