Spindle speed S, directions of rotation

Functionality
The spindle speed is programmed under the address S in revolutions per minute, if the
machine has a controlled spindle.
The direction of rotation and the beginning or end of the movement are specified via M
commands.
Programming
M3
M4
M5
Remark: For integer S values, the decimal point can be omitted, e.g. S270.
Information
If you write M3 or M4 in a block with axis movements, the M commands become active
before the axis movements.
Standard setting: Axis movements will only start once the spindle has accelerated to speed
(M3, M4). M5 is also issued before the axis movement. However, it does not wait for the
spindle to stop. Axis motion already starts before the spindle comes to a standstill.
The spindle is stopped with the end of the program or RESET.
At the beginning of the program, the spindle speed is zero (S0).
Note: Other settings can be configured via machine data.
