MC_AbortTrigger
Description
-
- This function block starts a motion-related action and therefore stores data for calculations and error checking. Please see Calling Function Blocks Multiple Times in the Same Cycle if you are using a dual-core controller.

TriggerInput |
Description |
Specifies the Fast InputThe 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 that was specified in the MC_TouchProbe function block which is to be aborted. The elements of TriggerInput are as follows: InputID INT; 0 = Touch Probe 1 / Capture Engine 0 1 = Touch Probe 2 / Capture Engine 1 Range is [0,1] Direction INT; 1 = rising edgeA rising edge is the transition of a digital signal from low to high. It is also called positive edge, 2 = falling edge TrigID INT; is the axis number of the input. 0 indicates that the trigger axis is to be the same as Axis.AXIS_NUM.
