Cam Operation

Cam operation synchronizes the position of the slave axis with the master axis according to a cam
table. Start cam operation with the MC_CamIn (Start Cam Operation) instruction. End cam operation
with the MC_CamOut (End Cam Operation) instruction or the MC_Stop instruction. Create a cam table
using the Cam Editor in the Sysmac Studio and download it to the CPU Unit. Use the Synchronization
menu command of the Sysmac Studio to download the project to the CPU Unit.
