Motion control is a sub-field of automation, encompassing the systems or sub-systems involved in moving parts of machines in a controlled manner. The main components involved typically include a motion controller, an energy amplifier, and one or more prime movers or actuators. Motion control may be open loop or closed loop. In open loop systems, the controller sends a command through the amplifier to the prime mover or actuator, and does not know if the desired motion was actually achieved. Typical systems include stepper motor or fan control. For tighter control with more precision, a measuring device may be added to the system (usually near the end motion). When the measurement is converted to a signal that is sent back to the controller, and the controller compensates for any error, it becomes a Closed loop System.
Typically the position or velocity of machines are controlled using some type of device such as a hydraulic pump, linear actuator, or electric motor, generally a servo. Motion control is an important part of robotics and CNC machine tools, however in these instances it is more complex than when used with specialized machines, where the kinematics are usually simpler. The latter is often called General Motion Control (GMC). Motion control is widely used in the packaging, printing, textile, semiconductor production, and assembly industries. Motion Control encompasses every technology related to the movement of objects. It covers every motion system from micro-sized systems such as silicon-type micro induction actuators to micro-siml systems such as a space platform. But, these days, the focus of motion control is the special control technology of motion systems with electric actuators such as dc/ac servo motors. Control of robotic manipulators is also included in the field of motion control because most of robotic manipulators are driven by electrical servo motors and the key objective is the control of motion.
SIMOTION – the high-end motion control system
SIMOTION, the proven high-end motion control system, features optimal performance for all machine concepts as well as maximum modularity. With SCOUT TIA, you can rely on a consistent engineering that is integrated in the Totally Integrated Automation Portal (TIA Portal). Drive-integrated SINAMICS safety functions are of course also available for your customized safety concepts.
With the new software versions, SIMOTION supports object-oriented programming (OOP), the OPC UA communication protocol, as well as user program tests in the engineering without hardware. Thereby, SIMOTION further optimizes its benefits with regard to modularity, openness, and efficient software development.
To compete on a global scale, industry requires powerful, versatile, and efficient motion control applications that work with precision. Machine builders have to adapt to these requirements and also continue to understand, implement, and reliably meet the very specific and individual requirements of their industrial customers.
The proven, modular, and scalable SIMOTION portfolio featuring high-end functions is the optimal solution for motion control applications in machine building when modularity, maximum precision, and speed are required. You can use SIMOTION to implement a wide variety of tasks and requirements with regard to motion control and adapt them for any industry with a motion control focus. for more info contact us! email@example.com
