• Procedure for Specifying Absolute Mode in Infinite Length Mode Axis
Reference codes signify the direction of rotation and reference angles signify absolute
position as shown in the figure below when absolute references are set in Infinite Length
Mode Axis.
Refer to the following figures where the current position is specified at position 180 °.
• The software limit function is disabled when Infinite Length Positioning is selected.
• When moving to 0
° by specifying Absolute Mode in Infinite Length Mode Axis, the axis does not
move counterclockwise even if -0.0 is specified. Specify -360.0 to move the axis counterclock-
wise.
