Control oscillation via synchronized actions
With this mode of oscillation, an infeed motion may
only be executed at the reversal points or within
defined reversal areas.
Depending on requirements, the oscillation
movement can be
• continued or
• stopped until the infeed has been finished
executing.
Sequence
1. Define oscillation parameters
The parameters for oscillation should be defined
before the movement block containing the
assignment of infeed and oscillating axes and the
infeed definition (see "Asynchronized oscillation").
2. Define motion-synchronized actions
The following synchronization conditions can be
defined:
• Suppress infeed until the oscillating axis is
within a reversal area (ii1, ii2) or at a reversal
point (U1, U2).
•
Stop oscillation motion during infeed at
reversal point.
• Restart oscillation movement on completion of
partial infeed.
• Define start of next partial infeed.
3. Assign oscillating and infeed axes as well as
partial and complete infeed.
