The following table shows the "positioning data" setting items for the reference
axis and interpolation axis.

M code –
: Setting always required
: Set according to requirements (Set to "–" when not used.)
: Setting restrictions exist
– : Setting not required (Unrelated setting item, so any setting value will be ignored. Use the initial
value or a value within the setting range.)
: For 2-axis interpolation, the partner axis is set. If the self-axis is set, an error "Illegal interpolation
description command (error code: 521)" will occur. For 3- and 4-axis interpolation, the axis setting
is not required.
: Refer to Section 5.3 "List of positioning data" for information on the setting details.
