Return to the contour after the machine axes were moved during a
program interruption that was not performed with the INTERNAL
STOP function.
Return to the contour after a block scan with RESTORE POS AT N,
for example after an interruption with INTERNAL STOP.
Depending on the machine, if the position of an axis has changed
after the control loop has been opened during a program
