(3) Linear type (workpiece coordinate position linear type)
(a) The coordinate position counter other than the workpiece coordinate position is displayed
in the range of 0 to 359.999°.
The workpiece coordinate position is displayed in the range of 0 to ±99999.999°.
(b) The movement is the same as the linear axis.
(c) During reference position return, the axis moves in the same manner as the linear axis until
the intermediate point.
The axis returns with a rotation within 360° from the intermediate point to the reference
position.
(d) During absolute position detection, even if the workpiece coordinate position is not within
the range of 0 to 359.999°, the system will start up in the range of 0 to 359.999° when the
power is turned ON again.

(4) Linear type (all coordinate values linear type)
(a) The all-coordinate position counter is displayed in the range of 0 to 99999.999°.
(b) The movement is the same as the linear axis.
(c) During reference position return, the axis moves in the same manner as the linear axis until
the intermediate point.
The axis rotates by the difference from the intermediate point to the reference position and
returns to the reference position.
(d) During absolute position detection, the system starts up at the position where the power
was turned OFF when the power is turned ON again.
