2.6.1.2 Repositioning on contour with controlled REPOS
Approach modes
Influence path axes individually
During SERUPRO approach, a REPOS operation is initiated in order to reposition to the
contour. A large number of axes, which the user can control by means of interface signals, is
frequently moved. The operator panel interface supplies the offsets per channel axis, which
REPOS intends to traverse.
Repositioning of individual path axes can be controlled by the PLC and, therefore, has
priority over the actual RMI, RMB and RME commands in the part program.
RMI: Repositioning to interruption point
RMB: Repositioning to start of block
RME: Repositioning to end-of-block position
RMN: Repositioning to next point on path
Repositioning with RMN
Like RMI, RMB, and RME, the RMN function (REPOS Mode Next) is redefined for
SERUPRO approach. After an interruption, the repositioning block is not started again
completely with RMN, but is merely executed as follows from the next path point:
At the time REPOSA is interpreted, position (B) is referenced in order to find point C at the
interruption block with the shortest distance to B. The repositioning block moves from B to C
to the end position.

B Position reached using JOG key
after the SERUPRO operation.
C SERUPRO approach moves from B
after C as C is the point next to B in
target block 2-3.
