t speed
Constant surface speed Gx96
G96: Main spindle; Gx96: Spindle x (x: 1...3)
The spindle speed is dependent on the X position of the tool tip or on
the diameter of the drilling or milling tool.
Speed Gx97
G97: Main spindle; Gx97: Spindle x (x: 1...3)
Constant spindle speed.

Parameter
S Cutting speed in m/min or ft/min
If you call a drilling tool while a constant cutting speed is
active, the Control automatically calculates the spindle
speed from the programmed cutting speed and activates
it with Gx97. To prevent inadvertent rotation of the
spindle, program the spindle speed first and then T.
