■Restrictions
In the following cases, the 3-axis helical interpolation control cannot be set.
• When "degree" is set in "[Pr.1] Unit setting" of the reference axis and circular interpolation axis
• When the units set in "[Pr.1] Unit setting" are different between the reference axis and circular interpolation axis (The
combination of "mm" and "inch" is possible.)
• When "reference axis speed" is set in "[Pr.20] Interpolation speed designation method"
• When the value out of the range of "0 to 999" is set in the number of pitches ("[Da.10] M code/Condition data No./Number
of LOOP to LEND repetitions/Number of pitches")
In the following case, an error occurs and the positioning will not start. During the positioning control, the operation stops
immediately at the detection of the error.
Error cause
When the radius exceeds 536870912 (= 2
the 2-axis circular interpolation control is possible is 536870912 (= 2
Start point address = Center point address
End point address = Center point address
When the center point address is out of the range of -2147483648 (-2

■Positioning data to be set
When using the 3-axis helical interpolation control with center point designation (ABS helical right, ABS helical left), set the
following positioning data.
