Example of operation
Examples of differences in the operation and counter displays according to the type of rotation
coordinate are given below.
(The workpiece offset is set as 0°.)
(1) Rotary type (short-cut invalid)
(a) The machine coordinate position, workpiece coordinate position and current position are
displayed in the range of 0 to 359.999°.
(b) For the absolute command, the axis moves according to the sign by the excessive amount
obtained by dividing by 360°.
N3
(2) Rotation type (short-cut valid)
(a) The machine coordinate position, workpiece coordinate position and current position are
displayed in the range of 0 to 359.999°.
(b) For the absolute command, the axis rotates to the direction having less amount of
movement to the end point.
