In case there is an axis indicated as the R-axis in All Axes Parameter No. 56, establish the
setting in All Axes Parameter No. 57 “Coordinate System Definition 1 R-Axis Coordinates
Direction Setting”.

Relation between direction
of rotation from X-axis to
Y-axis and R-axis direction
in base coordinate system
0: Same direction
1: Opposite direction
(All Axes Parameter No. 57 is the parameter to define the relations of X-axis, Y-axis and
R-axis in the base coordinate system.
In case this parameter is not established correctly, the axes will not operate as expected.
Pay attention when establish the setting for this parameter as the controller cannot judge
right or wrong for the contents of the setting.)
Establish the setting as described below for the value in All Axes Parameter No. 57.
(Example) In the construction below, Rb positive direction (clockwise) is opposite the rotating
direction from Xb positive direction to Yb positive direction R’ (counterclockwise),
thus All Axes Parameter No. 56 should be set to “1”.
