We will be using CtrlX drives with a Beckhoff controller for servo motion control. The drives will be in CSP mode, so only command position will be sent to the drive. On the one hand we want the bus cycle time as high as possible, because then we have a lot of margin for the code execution in the Beckhoff controller (f.i. in a 5ms controller cycle you can run more code then in a 1 ms controller cycle). On the other hand we want that the motion of our servomotor follows perfectly the motion command from the controller. I suppose that very short point to point motions require a short bus cycle (nc-task), but how do you make the relation between your motion profiles and the minimum NC-Cycle time?
