As hardware I have PLC 1769-L27ERM-QBFC1B, HMI PVW600 Compact, Switch Stratix 2000 and 2 PowerFlex 755 with encoder card 20-750-ENC-1. The movement has to be made with some sort of a E-CAM between the main supply engine and the rotating knife, but I don´t know how to configure the CAM. Can anyone help me with this? All I need is an example, because I don´t know wher to start. I have all the motor data, the ratio, etc...but I don´t know how to use this data.... [/INST] A good place to start is the drives accelerator toolkit. The MCCP and MAPC instructions are sophisticated and it will take a LOT of time to answer questions via forum messages like this. http://www.emea.rockwellautomation.com/oem/en/misc/free_design_tools.aspx Another place to look for assistance is your local Rockwell distributor and representative. If you have purchased the hardware, they should be very willing to help you. Even if you have not made the purchase, they should lend some assistance. If this is a class project though, a theoretical exercise, keep in mind the help you're asking for normally commands an hourly rate from a systems integrator that might surprise you. \\n </s>
