`MC_CamTableSelect` (FB)

FUNCTION_BLOCK MC_CamTableSelect

This function block selects the CAM tables by setting the connections to the relevant tables

A virtual axis can be used as master axis.
MC_PProfile is an ABB specific data type.
CamTableSelect makes data available. It prepares the provided data to be used by MC_CamIn or MCA_CamInDirect

Example on adding a CAM table

CamTable:ARRAY[0..2]OF MC_PProfile := [

(Master_position:= 0, interpolation_point:= 0, Velocity_ratio:= 1, Acceleration_ratio:= 1 ), (Master_position:= 10, interpolation_point:= 10, Velocity_ratio:= 1, Acceleration_ratio:= 1 ), (Master_position:= 20, interpolation_point:= 15, Velocity_ratio:= 1, Acceleration_ratio:= 1 ),

];

Note

User can utilize CAM editor (Cam table ABB basic) in Automation builder to generate Cam table automatically. User can also use MCA_CamStructureSelect function block which is similar to MC_CamTableSelect but give more features , and to be used with Cam Editor (Cam table ABB ). For more details refer to Automation builder help.

InOut:

Scope	Name	Type	Comment
Input	`Execute`	`BOOL`	Starts the function block at rising edge
	`MasterAbsolute`	`BOOL`	CamTable holds absolute positions for master. TRUE = Absolute, FALSE = Relative coordinates
	`SlaveAbsolute`	`BOOL`	CamTable holds absolute positions for slave. TRUE = Absolute, FALSE = Relative coordinates
	`Number_Of_Pairs`	`INT`	Number of sampling points, number of elements in CamTable
	`iType`	MC_ABB_iTypes_Enum	Type of interpolation. Possible values are: MCA_SPLINE_COMPLETE MCA_SPLINE_NATURAL MCA_POLY5 MCA_POLY3 MCA_LINEAR
	`CamTable`	POINTER TO MC_PProfile	Reference to CAM description, points to an array of MC_PProfile. User can use the Cam Editor (Cam table ABB basic ) to generate the Cam points
Output	`Done`	`BOOL`	Shows the status of the function block. Done = TRUE if the execution is finished
	`Busy`	`BOOL`	The function block with Busy = TRUE has control on the axis
	`Error`	`BOOL`	Signals that error has occurred within function block
	`ErrorID`	ERROR_ID	Error identification. For error details refer to Enumeration ERROR_ID
	`CamTableID`	MC_Cam_Id	Refers to prepared data, to be used for MC_CamIn or MCA_CamInDirect
Inout	`Master`	Axis_Ref	Reference to master axis
Inout	`Slave`	Axis_Ref	Reference to slave axis
