Setting positioning data
When carrying out interpolation control, the same positioning data Nos. are set for the "reference axis" and the "interpolation
axis". The following table shows the "positioning data" setting items for the reference axis and interpolation axis.
: Setting always required, : Set according to requirements (Set to "" when not used.), : Setting restrictions exist
: Setting not required (Use the initial value or a value within the setting range.)

*1 The axis No. is set to axis to be interpolated No.1 for 2-axis linear interpolation, to axis to be interpolated No.1 and No.2 for 3-axis linear
interpolation, and to axis to be interpolated No.1 to No.3 for 4-axis linear interpolation.
If the self-axis is set, the error "Illegal interpolation description command" (error code: 1B22H) will occur. The axes that are not used are
not required.
Refer to the following for information on the setting details.
Page 452 Positioning data
Starting the interpolation control
The positioning data Nos. of the reference axis (axis in which interpolation control was set in "[Da.2] Control method") are
started when starting the interpolation control. (Starting of the interpolation axis is not required.)
The following errors or warnings will occur and the positioning will not start if both reference axis and the interpolation axis are
started.
• Reference axis: Interpolation while interpolation axis BUSY (error code: 1A98H)
• Interpolation axis: Control method setting error (error code: 1B24H), start during operation (warning code: 0D00H).
