9.8 SPINDLE POSITIONING
The spindle positioning function moves the spindle connected to the
spindle motor by a given angle so that the workpiece attached to the
spindle is positioned at a desired angle.
With this function, any portion of the workpiece can be drilled.
The spindle position is detected by the position corder attached to the
spindle.
Whether to use the spindle for spindle positioning (spindle positioning
mode) or to use the spindle for spindle rotation (spindle rotation mode)
is command by special M code (set by parameters).
- Move command
When commanded:
G00 C_ ; (C is arbitrary axis address)
The spindle is positioned to the commanded position by rapid traverse.
Absolute (G90) and incremental (G91) command, as well as decimal
point input is possible.
- Increment system
Least input increment: 0.001deg
Detection unit: (360 times N)/4096 deg.
N : Combination ratio of position coder and spindle (N=1, 2, 4, 8, . .)
