以下示例演示如何创建和使用CAM表。
请参考Axis Setup Procedure了解如何设置轴的说明和示例。

'**********************************************************************************************************
' File:			CAM_MOVE.PRG
' Purpose:		Move two axes with CAM table and master-slave
' Version:		1.00
' Author:		Nir Geller
' Description:	This is an example of use of a CAM table. Initialize a CAM table with a sinus function character,
'				and set master - slave relations between two axes. Move the master axis and see how the slave axis
'				follows according to the cam table.
'
'				Record or watch the PFB of AX_MASTER and AX_SLAVE.
'
'**********************************************************************************************************

'Declaring a cam-table type global variable:
common shared AX_MASTER as generic axis = A1
common shared AX_SLAVE as generic axis = A2
common shared CamTable1 as cam

program

	call SetCAM

 
	attach AX_MASTER
	attach AX_SLAVE

 
	'call EC_SET_MOTION_OPMODE(AX_MASTER, POSITIONMODE)

 
	AX_MASTER.en = 1
	AX_SLAVE.en = 1
 
	sleep 1000
 
	while 1
 
		MOVE AX_MASTER 1000 vcruise=1000 starttype=immediate abs = 1

 
		while AX_MASTER.IsMoving <> 0
			sleep 1000
		end while
 

 
		MOVE AX_MASTER 0 vcruise=1000 starttype=immediate abs = 1

 
		while AX_MASTER.IsMoving <> 0
			sleep 1000
		end while
 
 
	end while
 
	detach AX_MASTER
	detach AX_SLAVE

end program
