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.
Procedure
1. Select the "Parameter" operating area.
2. Press the "Setting data" and "Spindle data" softkeys.
The "Spindles" window opens.
3. If you want to change the spindle speed, place the cursor on the "Maxi‐
mum", "Minimum", or "Spindle speed limitation at G96" and enter a new
value.
