NOOVERLAP program instruction motion. The only conditions that force an axis to make a larger change are if SINGLE is specified, or if a software limit stop would be violated. When NOOVERLAP is set, the setting of SINGLE or MULTIPLE mode is ignored. As with other user program errors, the error condition generated as a result of the NOOVERLAP test can be trapped by a standard REACTE subroutine if desired.
