Function Block - Adds a Superimposed Axis to the Axis’s list of assigned superimposed axes.
This feature allows the application program to superimpose the moves of multiple axes (Superimposed Axes) on top of the move of another axis (Receiving Axis).
- This is performed internally by adding the command deltas of the Superimposed Axes to the command delta of the Receiving Axis.
- A maximum of four different Superimposed Axes can be superimposed upon a Receiving Axis.
-
-
- This function or function block returns cached data.
- See Program a Multi-Core Controller.
- While the Superimposed Axis is on this list, its command deltas are added to the Axis’s command deltas.
- The Axis and the SuperimposedAxis must have the same update rate.
- The OK output goes high to indicate the function executed successfully.
- If the OK output does not go high, one of these errors is detected:
- Axis and SuperimposedAxis do not have the same update rate.
- Four different superimposed axes have already been assigned to Axis.
- The axis is not a valid axis.
- The axis is not a servo or virtual axis.
- SuperimposedAxis is not:
- A valid axis number.
- A servo or virtual axis.
- Axis could not acquire PLC motion engine lock.
