Automatic Operation (Position Control)8-148.2.2 Type of Interpolation Control (Three-axis Interpolation)• The following types and operation specification methods are available for the 3-axisinterpolation.• The axes in the relation of an interpolation are called 1st axis, 2nd axis and 3rd axis for the3-axis interpolation. Also, the 1st, 2nd and 3rd axes are automatically allocated from thesmallest axis number in ascending order.

Also, in the case of the pass point specification,the coordinate of the pass point on arc is specified as the data of 1st-axis (X-axis) auxiliarypoint and 2nd-axis (Y-axis) auxiliary point of positioning data• When the control method is increment, for the both center point and pass point, theincrement coordinate from the start point is specified.• When the start point and the operation done point is the same, it performs one circularoperation when using the center point method. However, when using the pass point method,an error occurs.• In case of the pass point method, when the start point, pass point and operation done pointexist in the same straight line, an arc is not comprised, and an error occurs.
