11.2 Oscillation controlled via synchronized actions

The synchronized actions

The synchronized motion actions listed below are

used for general oscillation.

You are given example solutions for individual tasks

which you can use as modules for creating user-

specific oscillation movements

In individual cases, the synchronization conditions

can be programmed differentially.

Vocabulary words

WHEN ... DO ...

WHENEVER ... DO

You can implement the following functions with the

language resources described in detail below:

1. Infeed at reversal point

2. Infeed at reversal area.

3. Infeed at both reversal points.

4. Stop oscillation movement at reversal point.

5. Restart oscillation movement

6. Do not start partial infeed too early.

The following assumptions are made for all

examples of synchronized actions presented here:

• Reversal point 1 < reversal point 2

• Z = oscillating axis

• X = infeed axis

You will find more information on synchronized

motion actions in Section 11.3.
