Specifying the repositioning point (not for SERUPRO approaching with RMN)

With reference to the NC block in which the program run has been interrupted, it is possible

to select one of three different repositioning points:

● RMI, interruption point

● RMB, block start point or last end point

● RME, block end point

In the case of a minus sign, approach is behind the interruption point or, with

The distance between interruption point and approach point depends on the value of
