Path traversing behavior

9.9 Repositioning at contour (REPOSA/L, REPOSQ/H, RMI, RMN, RMB, RME)

The sign DISPR is evaluated. In the case of a plus sign, the behavior is as previously.

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

block start point.

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

Even for higher values, this point can lie in the block end point at the maximum.

Sample application:

A sensor will recognize the approach to a clamp. An ASUP is initiated to bypass the clamp.

Afterwards, a negative DISPR is repositioned on one point behind the clamp and the

program is continued.

SERUPRO approach with RMN

If abort is forced during machining at any position, the shortest path from the abort point is

approached with SERUPRO approach and RMN so that afterward only the distance-to-go is

processed. The user starts a SERUPRO process at the interruption block and uses the

JOG keys to move in front of the problem component of the target block.

For SERUPRO, RMI and RMB are identical. RMN is not limited to SERUPRO but is generally
