11.9 MULTIPLE ROTARY CONTROL AXIS FUNCTION
General
A rotary axis is specified in the ROT bit (bit 1 of parameter 1008).
When incremental programming is specified for the rotary axis, a
specified value directly determines the travel distance. When absolute
programming is selected, either of the following two operations can be
specified by the RSR bit (bit 2 of parameter 1007).
(1) The NC unit rounds down the value specified in the absolute
command (G90) to a value indicating a full turn or less. The
difference between the rounded value and the current position is
the angular displacement. When the bit 5(INC) in parameter No.
1007 is specified, short-cut control can be executed. When the
difference between the rounded value and the current position
indicates more than a half turn, the short-cut control function
allows reverse rotation up to the specified position.
(2) The sign of the specified value indicates the direction of rotation.
(The plus sign (+) indicates counterclockwise rotation and the
minus sign (-) clockwise rotation). The absolute value of the
specified value indicates the destination.
An absolute value of a position relative to the rotary axis is represented
by an equivalent value within the amount of travel for a single
revolution as specified in parameter 1260.
