Path traversing behavior

8.6 Repositioning to a contour (REPOSA, REPOSL, REPOSQ, REPOSQA, REPOSH, REPOSHA, DISR,

DISPR, RMI, RMB, RME, RMN)

Job planning

484 Programming Manual, 07/2010, 6FC5398-2BP40-0BA0

The following applies to the REPOSH and REPOSQ circular motions:

The circle is traversed in the specified working planes

G17 to G19.

If you specify the third geometry axis (infeed direction) in the approach block, the

repositioning point is approached along a helix in case the tool position and programmed

position in the infeed direction do not coincide.

In the following cases, the control automatically switches over to linear approach

REPOSL:

● You have not specified a value for

DISR.

● No defined approach direction is available (program interruption in a block without travel

information).

● With an approach direction that is perpendicular to the current working plane.
