PLCs & Controllers

About plcs & controllers

Motion controllers coordinate the movement of servo and stepper axes on a machine: positioning, speed control, electronic gearing and cam profiles, and interpolated moves where several axes follow one path. Motion CPUs and technology CPUs combine that motion control with the logic of a programmable logic controller (PLC), so one controller runs both the sequence of the machine and its axes. Machine automation controllers add networking, data handling and often safety in the same platform. The controller sits at the centre of the machine: it reads sensors and operator inputs, runs the program, and sends position and speed commands to the servo drives over a real-time network.

This page lists 54 controllers and modules from ABB, Danfoss, Delta Electronics, Eaton, Mitsubishi Electric, OMRON, Siemens and Yaskawa, including motion controllers, motion CPUs and modules, machine automation controllers and technology CPUs. Use the brand shortcuts or the filters to narrow the list by brand and product type, open a product for its information sheet, and add the models you need to one quotation request.
