5.3 INCRMENTAL COMMAND TYPE SPINDLE ORIENTATION
(SPINDLE ROTATION SPEED CONTROL)
Optional function
5.3.1 Overview
Incremental command type spindle orientation is a function that
expands the spindle orientation in which a stop position is specified
externally using a position coder.
This function is intended to move the spindle from the position where
it was when a spindle orientation command was input to a position
specified incrementally. It positions the spindle as follows:
The spindle rotates from the position where it was when a spindle
orientation command was input through an incremental angle
specified from the PMC via the CNC. When the spindle orientation is
completed, a completion signal is sent to the PMC via the CNC.
Using the function enables:
(i) Spindle motor-based turret indexing
(ii) Spindle rotation speed control if a command multiplier value
(parameter-specified value) is set to "4096"
NOTE
1 Using this function requires the spindle orientation
CNC software option.
2 Up to about 120 revolutions can be specified as the
maximum allowable spindle speed.
