Spindle control mode

When control mode?
The spindle is in control mode with the following functions:
● Constant spindle speed S, M3/M4/M5 and G94, G95, G97, G33, G63
● Constant cutting rate G96 S, M3/M4/M5
Requirements
A spindle position actual value sensor is absolutely essential for M2/M4/M5 in conjunction
with revolution feedrate (G95, F in mm/rev or inch/rev), constant cutting rate (G96, G97),
thread cutting (G33).

The spindle changes to oscillation mode if a new gear stage has been specified using
automatic gear stage selection (M40) in conjunction with a new S value or by M41 to
M45. The spindle only changes to oscillation mode if the new gear stage is not equal to
the current actual gear stage.
When the new gear stage is engaged, the IS "Oscillation mode" (V390x 2002.6) is reset
and the spindle is switched to control mode with the IS "Gear changed" (V380x 2000.3).
The last programmed spindle speed (S value) is reactivated.
To stop the spindle from rotation (M3 or M4) with orientation or to reorient it from standstill
(M5), SPOS, SPOSA or M19 are used to switch to positioning mode.
M3, M4 or M5 are used to change to control mode if the orientation of the spindle is to be
terminated. The last programmed spindle speed (S value) is reactivated.
If the orientation of the spindle is to be terminated, M41 to M45 can be used to change to
oscillation mode. When the gear change is complete, the last programmed spindle speed
(S value) and M5 (control mode) are reactivated.
Tapping with compensation chuck (thread interpolation) is activated via G331/G332.
SPOS must first be used to set the spindle to position-controlled operation.
