Path traversing behavior
8.6 Repositioning to a contour (REPOSA, REPOSL, REPOSQ, REPOSQA, REPOSH, REPOSHA, DISR,
DISPR, RMI, RMB, RME, RMN)
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
RMI DISPR=... or RME DISPR=... allows you to select a repositioning point which sits before
the interruption point or the block end point.
DISPR=... allows you to describe the contour distance in mm/inch between the repositioning
point and the interruption before the end point. Even for high values, this point cannot be
further away than the block start point.
If no DISPR=... command is programmed, then DISPR=0 applies and with it the interruption
point (with RMI) or the block end point (with RME).
DISPR sign
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.
