an also close a speed loop internally.
Motion controllers are mainly divided into three categories, namely PC-based, dedicated controller, and PLC. Among them, PC-based motion controllers are widely used in electronics, EMS and other industries; the representative industries of dedicated controllers are wind power, photovoltaics, robotics, molding machinery, etc.; PLC is favored in rubber, automotive, metallurgy and other industries. Drive or amplifier: used to convert the control signal (usually a speed or torque signal) from the motion controller into a higher power current or voltage signal. The more advanced intelligent drive can close the position loop and speed loop by itself to obtain more precise control.
Actuators: such as hydraulic pumps, cylinders, linear actuators or motors to output motion. Feedback sensor: such as photoelectric encoder, resolver or Hall effect device, etc., used to feedback the position of the actuator to the position controller to realize the closure of the position control loop. Numerous mechanical components are used to convert the motion form of the actuator into the desired motion form, including gearboxes, shafts, ball screws, toothed belts, couplings, and linear and rotary bearings.
The emergence of motion control has further promoted electromechanical control solutions. For example, in the past, both cams and gears needed to be realized by mechanical structures, but now they can be realized by electronic cams and electronic gears, eliminating the return, friction and wear of the mechanical realization process.
Mature motion control products not only need to provide path planning, forward-looking control, motion coordination, interpolation, kinematics forward and inverse solutions, and drive motor command output, etc., but also need to have engineering configuration software (such as SIMOTION’s SCOUT) and syntax interpreter (Not only refers to its own language, but also includes IEC-61131-3 PLC language support), simple PLC function, PID control algorithm realization, HMI interactive interface, fault diagnosis interface, advanced motion controller can also realize safety control, etc. .
