Remarks
-
-
This function or function block returns cached data.
See Program a Multi-Core Controller.
- See Function Blocks - General Rules about how inputs and outputs work.
- If a motor An actuator focused to a movement, converting electrical energy in a force or torque. is associated with the axis, it does not move when MC_SetPos is executed.
- MC_SetPos does not cause any motion.
- It applies an offset to the command and actual positions.
- MC_SetPos sets the accumulated Superimposed distance value for the input axis to 0 (zero).
- See Axis Positions Data for more information.
- This function block replaces MC_SetPosition.
-
- This function block starts a motion-related action and stores data for calculations and error checking.
See Call Function Blocks Multiple Times in the Same Cycle if using a dual-core controller.

FFLD Language Example
-
- This function block finishes immediately.
Because of this, the Done output does not get set to FALSE in a second call to the same MC_SetPos instance unless there is an error.
If the application needs to look for a state change to determine if a particular call to MC_SetPos was successful, then useAND
for the rising edge of the Execute input, the Done output, and the inverse of the Error output.
This FFLD Language example shows how this can be done.
In the example, the SetPosSuccessful variable is set toTRUE
for one cycle upon a successful call to the MC_SetPos instance.
