Description

The indicated oscillation zone is superseded by a previous zone.

Remedy

Oscillation zone transitions always occur when the oscillation axis is at its zero position. This means that when the machine reaches a position boundary, oscillation may continue based on the previous positions oscillation parameters until the oscillation axis reaches its zero position. If positions are taught very close together, oscillation zones may be superceded by a previous zone
