Function Block - Homing by setting Actual Position to the position of the feedback.

Inputs

Input	Data Type	Range	Unit	Default	Description
En	BOOL	FALSE, TRUE	N/A	No default	Enables execution. Used in the FFLD editor only.
Execute	BOOL	FALSE, TRUE	N/A	No default	Request the homing step procedure at the rising edge.
AxisID	AXIS_REF	1 to 256	N/A	No default	Name of a declared instance of the AXIS_REF library function. See AXIS_REF Structure.
Mode	BOOL	FALSE, TRUE	N/A	No default	Define the actual position assignment source. 0 (zero) = Use drive feedback position for actual position. 1 = Use once per rev feedback position.

Output	Data Type	Range	Unit	Description
Done	BOOL	FALSE, TRUE	N/A	Indicates the move completed successfully. The Command Position has reached the endpoint.
Busy	BOOL	FALSE, TRUE	N/A	High from the moment the Execute input goes high until the time the move is ended.
Active	BOOL	FALSE, TRUE	N/A	Indicates this move is the Active move.
CommandAborted	BOOL	FALSE, TRUE	N/A	Indicates the move was aborted.
Error	BOOL	FALSE, TRUE	N/A	Indicates either: An invalid input was specified. The move was terminated due to an error.
ErrorID	INT	Enumerated	N/A	Indicates the error if the Error output is set to TRUE. 1 = Desired SetPosition is outside of Rollover period.

Performs a static homing function by setting Actual Position to the position of an absolute encoder.
No physical motion is performed in this mode.
Equivalent to MC_SetPosition is performed with SetPosition coming from absolute encoder reading but with the option of using the once per rev feedback value.
