How do motion controllers work | Motion controller in delhi

 

Motion control is a bit of a specialty in automated control systems and its use is not basic, as it can provide advanced

machine functionalities. It provides the means to move the machine tooling or the part itself in a controlled, and often

precision, rotary or linear manner. Precimotion is the best solution for Motion controllers in India. Our engineering facilities are state-of-the-art and our team of professionals is in demand for their capability to existing gears and gearboxes for diverse applications and other services such as Servo planetary, Strainwave gearboxes, Six axis, Pick & place robots, AGV.

Historically, motion control had its own controllers and application software with motion-control algorithms to get the work done. Today, much of the motion control can be performed in the main control-system controller, if chosen carefully but motion still requires specialty amplifiers/drives, motors, position feedback devices and precision mechanical linkages or actuators.

 

A motion controller contains the motion profiles and target positions for the application and creates the trajectories for the motor and/or actuator. Motion control is often closed loop so it monitors the actual path and corrects for positions or velocity errors. The motion controller often outputs position commands via +/-10 Vdc signals for a servo motor drive or step and direction signals to a stepper motor drive. Industrial Ethernet or similar protocols are used for commanding many modern drives.

 

Motion control board: Motion control board mounts functions to output pulse train at designated pulse number or frequencies. It can automatically output control pulse according to motion parameters such as target position, velocity, acceleration and deceleration rates, etc. It has various limit input functions for positioning the controllers. Motor driver controls the motor itself. Motion control board outputs a pulse signal for the motor driver unit and controls the motor. It is connected with a pulse input type stepping motor or servo motors.

 

How does it work: 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 actuator), the motion controller generates motion profiles. These are the sequences of position command 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 command which is then sent to the drive.

 

Kinds of motion controller exist: In industry there are several motion controllers that differ in size and category. However, it is possible to identify three main types:

 

• Autonomous controllers: complete systems that feature electronics, power supply and external connections in a single physical container.
• PC based controller: controllers mounted on the motherboard of a PC’s to generate and execute motion profiles.

• Microcontrollers: MCUs (MicroController Units) are devices which are integrated on single electronic circuits to control a motor.
