Define motion-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
Note
In individual cases, the synchronization conditions can be programmed differentially.

Functions
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
