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 …
when ... , do
WHENEVER … 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.
