10.5 Spindle Orientation Function
Spindle orientation signal (SOR) G29.5
When this signal is '1', spindle stops; while is '0', spindle is spinning in a certain speed set by data
parameter (No.3732) . No matter how is the gear state, spindle will rotate at a certain speed, so in the
mechanical spindle positioning, it can be used to rotate into the brake and pin and so on.
In M series, spindle motor can be made rotating in a certain speed by setting data parameter NO.3732,
in which situation because the rotating speed is constant in the gear switch devices, it can be used to
gear shift.When spindle stop signal SSTP is 1, spindle orientation signal SOR is invalid.
When bit parameter GST is 0, SOR signal is used for spindle orientation, of which speed is decided by
data parameter3732, while gear stage select signal does not change. For instance, if at the, SOR signal
turns to 1, while the speed data parameter 3732 set is not in the range of the low speed gear, due to
gear-stage signal is not alter, CNC will compute the corresponding speed still according to high speed gear
curve.When bit parameter GST is 1 SOR signal is used for control the motor speed. The output instruction
has no connection with gear-stage, set suitable spindle motor speed to control gear shift.
