Cam Tables and Cam Data Variables

The MC Function Module uses the cam profile curves that you create on the Cam Editor of the Sysmac
Studio as cam tables. The cam table data is handled as cam data variables in the user program in the
NY-series Controller.

*1 Use the Synchronization menu command of the Sysmac Studio to upload and download the project.
*2 The cam data variables that are uploaded cannot be changed on the Cam Editor. Refer to the following page
for the procedure to edit a cam data variable on the computer after editing it from the user program. Also, if the
project is rebuilt or the cam profile curve is changed from the Sysmac Studio, the cam data variable that was
uploaded is overwritten with the cam profile curve data.
*3 "Cam definition variable" is the generic term for cam property variables and cam node variables.
 Cam Table Data Flow
• Use the Sysmac Studio to download the cam profile curves that you created in the Sysmac Studio
to the NY-series Controller to save them as cam tables in the non-volatile memory in the Industrial
PC. When you upload a cam table to the Sysmac Studio, the cam table that was saved in the non-
volatile memory is uploaded.
• The cam tables that were saved in non-volatile memory are implemented as cam data variables in
the main memory after you download them or when the power is turned ON.
• You can use the user program to edit cam data variables and cam definition variables in the main
memory. Refer to 9-2-5 Cam Tables for information on cam data variables and cam definition vari-
ables.
• The MC_GenerateCamTable (Generate Cam Table) instruction in the user program can overwrite
the cam data variable in main memory according to the value of the cam definition variable.
• The motion control instruction MC_SaveCamTable saves the cam data variables in the main
memory to non-volatile memory.
• You can upload the cam definition variable that were created in the Cam Data Settings of the Sys-
mac Studio even after the variable is changed in the user program. If the cam definition variable
was created as a user-defined variable, you cannot upload it after it is changed in the user pro-
gram.
