Spindle Function (S Function)

The spindle speed is specified in rpm in Address S. The direction of spindle rotation is
selected with M3 and M4. M3 = right direction of spindle rotation, M4 = left direction of
spindle rotation. The spindle stops with M5.
3.1

Spindle speed(S), direction of spindle rotation(M3,M4,M5)

The spindle speed and direction of rotation values set the spindle in rotary motion.
Other spindles may be available in addition to the main spindle (e.g. the milling spindle or an
actuated tool on turning machines). As a rule, the main spindle is declared the master
spindle in the machine data. This assignment can be changed using an NC command.

SETMS
S... : Spindle speed in rpm for the master spindle
S<n>=... : Spindle speed in rpm for spindle <n>
Note
The speed specified with S0=... applies to the master spindle.
M3: Direction of spindle rotation clockwise for master spindle
M<n>=3: Spindle direction of rotation CW for spindle <n>
M4: Direction of spindle rotation counterclockwise for master spindle
M<n>=4: Spindle direction of rotation CCW for spindle <n>
M5: Spindle stop for master spindle
M<n>=5: Spindle stop for spindle <n>
SETMS(<n>): Set spindle <n> as master spindle
SETMS: If SETMS is programmed without the configured master spindle is used
instead.
n=1 : main(left) spindle
n=2 : live tool spindle (milling spindle)
