SMC_TRAFO_Gantry2Tool2 (FB)¶

FUNCTION_BLOCK SMC_TRAFO_Gantry2Tool2

Reverse transformations for gantry systems with tool offset. The tool is approximated by a rectangular triangle.

InOut:

Scope	Name	Type	Comment
Input	`pi`	SMC_PosInfo	Target vector position (x,y), ouptput of interpolator. SMC_POSINFO
	`dOffsetX`	`LREAL`	Additional offset for x-axis
	`dOffsetY`	`LREAL`	Additional offset for y-axis
	`dAlpha`	`LREAL`	Angle indicating orientation of tool, can be calculated by use of SMC_CalcDirectionFromVector
	`dToolA`	`LREAL`	Size of tool A = distance( set position) - (machine position)
	`dToolB`	`LREAL`	Size of tool B = distance( set position) - (machine position)
Output	`dx`	`LREAL`	Resulting position for x-axis
Output	`dy`	`LREAL`	Resulting position for y-axis
