We are trying to develop CAM profiles for a link arm mechanical system that we can set limits on either the jerk of the load or torque of the motor. We currently have a CAM that is optimized for motor torque based off the load inertia but this requires us to run the machine at 100%; which isn't always possible.
Using excel I can get CAMs to work for the accel, but I can't seem to remember how to know when I need to start decel based on position and how long it will take. Can someone point me in the right direction. I recall seeing some equations from Peter Nachtwey years ago; but I can't seem to find them now.
