MLTrigSetEdge

 Function A function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances. - Sets the edge configuration for a trigger block (e.g., rising, falling, etc.)

Inputs

Input	Data Type	Range	Unit	Default	Description
BlockID	DINT	-2147483648 to 2147483647	N/A	No default	ID number of the trigger block.
Edge	DINT	0, 2	N/A	1 (rising edge A rising edge is the transition of a digital signal from low to high. It is also called positive edge)	The edge to trigger on. 0 = disable the Fast Input The inputs are taken into account at each cycle depending on the system periodicity (for example each millisecond). Under certain circumstances this can be insufficient when more accuracy is needed, or if a quick response is required from the system. To fill the gap, a drive may have some Fast Input connections (generally one or two). When an event happens that triggers a Fast Input (e.g. when a sensor sends a rising edge), the detection of a signal occurs faster (which can be 1000 times more accurate than the system periodicity). Then the timestamp associated with this input can be provided to the IPC to take corrective action. 1 = rising edge. 2 = falling edge.

Outputs

Output	Data Type	Range	Unit	Description
Q	BOOL	No range	N/A	TRUE if block executed successfully. FALSE if execution is not successful.

Remarks

• This block should be called prior to calling MLAxisCfgFastIn.
• The value at the Edge input must match the value at MLAxisCfgFastIn’s Mode input.
