9. SPINDLE SPEED FUNCTION
419
CAUTION
1 Feed hold is invalid during spindle positioning.
2 Spindle positioning stops when emergency stop is applied;
restart with orientation operation.
3 Dry run, machine lock, and auxiliary function lock are not
available during spindle positioning.
4 The spindle positioning function and the serial spindle Cs
contour control function cannot be used together. If both
functions are used, positioning has priority.
5 Specify parameter No. 4962 even if semi-fixed angle
positioning is not used; otherwise M codes (M00 to M05) do
not work.
NOTE
1 Command spindle positioning with an independent block.
X- and Y-axis positioning cannot be commanded to the
same block.
2 Spindle positioning cannot be done by manual operation.
3 Automatic drift compensation is not effective for spindle
positioning. To adjust the amount of drift compensation for
each axis, set values manually and adjust the spindle
amplifier to minimize the spindle motor rotation at a voltage
of 0V. (parameter No. 3731). Insufficient adjustment
causes poor positioning accuracy. Drift compensation is not
needed with a serial spindle.
4 The machine coordinates for the spindle positioning axis
are displayed in pulses units.
