9. (S) SPINDLE SPEED AND SPINDLE ORIENTATION
Code S can have three different meanings:
a) Spindle speed.
The spindle speed is programmed directly in rev/min. by means of code S4.
Any value may be programmed between S0 and S9999; i.e. between 0 and 9999 rev/
min. This value is limited by the max. speed permitted by the machine; this limit is
set by a machine parameter.
The instruction book of the machine must be consulted in each particular case. The
controls on the front panel of the CNC may be used to achieve between
50 and 120% variation in programmed spindle speed.
These controls do not operate when carrying out the tapping canned cycle G84 or
when function G33 is activated the speed being fixed at 100% of the programmed
value.
b) Spindle orientation
If S4.3 is programmed after M19, it identifies the spindle’s stopping point in degrees,
referred to the encoder zero marker. The spindle will rotate according to parameters
P601(7) and P700 until the point identified by S4.3 is reached.
The spindle must have an encoder in order to use this function.
