On October 16, 2014, Dalian United Holdings, a leading electronic component distributor dedicated to the Asia-Pacific market, announced that its company has launched a high-precision motion control solution based on the ADI ADSP-CM40x and TI C2000 InstaSPIN.
Motion control is a branch of automation that uses some of the servo's equipment such as hydraulic pumps, linear actuators or motors to control the position and/or speed of the machine. Motion control technology enables the standardization and high-quality production process by machine instead of manual, which greatly improves labor productivity. With the further development of motion control technology and the further integration and upgrading of downstream traditional manufacturing, the demand for motion control related technologies and products will continue to be strong, especially in the packaging, printing, textile and assembly industries.
In response to the market demand for innovation in motion control technology, the company has launched ADI and TI high-precision motion control system solutions.

· The processor ADSP-CM40x integrates the industry's only embedded dual-channel 16-bit analog-to-digital converter with up to 13-bit accuracy, with a conversion speed of up to 380 nanoseconds;
· The processor is equipped with a 240-MHz floating-point ARM® CortexTM-M4 processor core;
· The processor is embedded with many motor control peripherals, such as high precision ADC, SINC filter, encoder input, PWM output unit that can drive multiple motors and rich communication interface;
· The use of an on-chip sinc filter saves the cost and engineering resources required to implement the same function in an FPGA;
· High precision current and voltage detection for improved speed and torque control performance;
· High-performance position detection performance using optical encoders and resolvers as position sensors;
· Prioritize security and protection, signal sampling and power device drivers should use isolation technology;
· Analog Devices' iCoupler digital isolators meet high voltage safety isolation requirements;
· Vector control and sensorless control using DSP high performance processors;
· Provide more efficient and flexible algorithms;
· Meet the needs of next-generation networking applications, using isolated interface chips;

· InstaSPINTM is embedded in a read only memory (ROM) of a particular PiccoloTM device;
· Saves design and motor parameter identification time, software automatic detection and torque control optimization, state-based motion planning speed adjustment, control adjustment and complete trajectory generation system;
· The embedded on-chip FASTTM observer algorithm has near-encoder performance, which provides a stable and reliable estimate of rotor flux, angle, speed and torque under global conditions only by analyzing current and voltage. The precise performance of the sensorless estimator makes physical sensors no longer necessary in all torque and speed control applications;
· Make the same solution compatible with all three-phase motors, synchronous (BLDC, SPM and IPM) and asynchronous (ACI);
· Identify motor parameters online and offline, and adjust the current controller online for stable operation. The online resistance re-estimation mode can be used to track the performance of the robust estimator under the most demanding low-speed loads.
· Low speed performance below 1 Hz (typical), zero speed stability, reverse steady state preservation;
· The flexibility of the gain system architecture to enable a function to call the FOC torque controller or a fully customizable control system with a fast software motor sensor;
