DC21FlyCut
D = Device(cam01,camming,camming2, camming3, camming4)
C = Calculation functions
The DC21FlyCut function execute the calculations necessary to be able to perform a linear fly cut. Passing parameters of length piece, acceleration/deceleration Slave, maximum speed of the masters in this type of cut, maximum speed Slave and various times needed to cut, the function calculates the areas of the cam program and writes about arrays special. Next is another function (WrCam) that deals with writing data to the device that you want. If there are problems in calculations, why physically not be execute, the type of error that occurred is returned in the “Error” variable.
Use this function to search the highest productivity of the machine running the slightest stroke can cut tank.

Error
After calling the function, if there are any errors the error variable takes certain values, the meaning of these values is summarized below:
0: calculation execute without errors
1: Master speed or Slave speed equal to 0
2: calculated slave speed greater than the maximum extra space-cutting
3: insufficient piece length
4: negative return space (insufficient piece length)
5: slave return speed greater than the maximum
6: insufficient time for the return
Operation notes
-
This function always calculates the cam dividing it into 15 sectors
-
The cutting sector is the sector 4 (rowex = 4). In this sector the codeM = 1000 to enable management of cutting output from the device ('funout' parameter of Camming device)
-
If, during operation, the speed of the Master exceeds that set as Master reference speed (“VriferM” parameter) the good operation of the cam is no longer guaranteed (the analog output of the slave could go into saturation)
