ITX:Servo control system engineers chiefly work in two well-defined areas. They design new motion control systems for conveyors, pick and place machines, gantries, machine tools, and much more. On the other hand, they might redesign an existing system that typically comprises older analog controllers, sensors, and drives. Of course, the new design task starts with a clean sheet of paper. Since this system did not exist before, all the specifications must be derived from calculations, simulations, or actual measurements on existing machinery.
