MC_StepDirect (FB)

FUNCTION_BLOCK MC_StepDirect

This function Block performs a static homing by directly forcing an actual position. No physical motion is performed in this mode. This is equivalent to a MC_SetPosition action, but clears the Homing State.

Note

This function block modifies actual position and sets to the “SetPosition” input value at the end.

InOut:

Scope	Name	Type	Comment
Input	Execute	BOOL	Starts the function block at rising edge
	SetPosition	LREAL	[u] Value of the absolute position to be set when homing is done. Range: Linear Axis: Maximum range is 16#7FFFFFFF in increments, if configured in units, range will be limited to equivalent of 16#7FFFFFFF increments Modulo Axis: Range will be limited by Modulo range defined
	BufferMode	MC_BufferMode	not supported, default mcABORTING used
Output	Done	BOOL	Shows the status of the function block. Done = TRUE if the execution is finished
	Busy	BOOL	The function block is not finished
	Active	BOOL	Indicates that the function block has control on the axis
	CommandAborted	BOOL	Command is aborted by another command from other PLCopen function block
	Error	BOOL	Signals that error has occurred within function block
	ErrorID	ERROR_ID	Error identification. For error details refer to Enumeration ERROR_ID
Inout	Axis	Axis_Ref	Reference to axis
