(Note): Refer to Section 5.3 "List of positioning data" for information on the setting details.
Restrictions
An error will occur and the positioning will not start in the following cases. The
machine will immediately stop if the error is detected during a positioning control.
 If the movement amount of each axis exceeds "1073741824 (=2
Composite speed" is set in "[Pr.20] Interpolation speed designation method"
The error "Outside linear movement amount range" (error code: 504) occurs at a
positioning start.
(The maximum movement amount that can be set in "[Da.6] Positioning
address/movement amount" is "1073741824 (=2
