Returning to the contour
With the RESTORE POSITION function, the TNC returns to the

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 interruption
