Spindle speed S

The spindle speed S is entered in revolutions per minute (rpm) in a
TOOL CALL block (tool call). Instead, you can also define the cutting
speed Vc in meters per minute (m/min).
Programmed change
In the NC program, you can change the spindle speed in a TOOL
CALL block by entering the spindle speed only:
Program a tool call: Press the TOOL CALL key
Ignore the dialog question for Tool number ?
with the NO ENT key
Ignore the dialog question for Working spindle
axis X/Y/Z ? with the NO ENT key
Enter the new spindle speed for the dialog
question Spindle speed S= ?, and confirm with
END, or switch via the VC soft key to entry of the
cutting speed.
If the number of the already inserted tool is entered in
the TOOL CALL block without specifying the tool axis,
then only the spindle speed will change.
If the tool axis is also entered in the TOOL CALL
block, the control will insert a replacement tool if a
replacement tool was defined.
Changing during program run
You can adjust the spindle speed during program run with the
spindle speed potentiometer S.
