Automation Direct India is a leading dealer and distributor of Yaskawa Motion Controllers in India. We distribute Yaskawa Motion Controllers in Chennai, Bangalore, Pune, Mumbai, Ahmedabad, Hyderabad and Delhi.
Let’s start with the basics. Motion controllers are special devices that control the engine operating modes. In other words, it’s the brain of every motion control system. As such, its task is telling the motor what to do based on the desired production outcome.
In fact, a motion controller contains the movement profiles and the target positions for the application, and creates the trajectories that the engine must perform to satisfy the commands. Motion control is often a closed circuit, so controllers monitor the actual path and corrects positioning or speed errors.
In feedback-based systems, motion controllers take an input command sent by the user, compare it with a feedback signal from the motor and apply corrective actions so that the desired input/position and actual output/position match with little – or zero – margin of error.
When creating trajectories for the motor (and/or actuator), the motion controller generates motion profiles. These are the sequences of position commands in relation to time that indicate to the motor where and how fast to place a load. Finally, the motion controller uses the trajectories created to generate the correct torque commands, which are then sent to the drive.
