System Design Considerations and Key Challenges and Value Propositions for Motor Control Solutions ADI

For motor control solutions, ADI offers a comprehensive portfolio of analog/digital converters, amplifiers, embedded processors, iCoupler® digital isolators, power management devices and real-time Ethernet solutions; High-performance devices and increased system integration help to achieve newer topology designs that add value to customers' differentiated designs. For example, faster-clocked processors can run more complex algorithms, high performance. The ADC can support higher performance current loop control and more.

The performance of the servo drive system is closely related to the performance and accuracy of the motion control system that the user ultimately constructs. In most cases, the final use can be a high-precision CNC machine system, a networked motion control system or a robot system. These systems require precise control of position and motor torque; ADI offers a complete solution that covers all critical components in the signal chain.

System design considerations and major challenges

精度 High-precision current and voltage detection improves servo speed and torque control performance in servo control. An ADC with multi-channel and simultaneous sampling capability that requires at least 12-bit accuracy. ADI offers a complete range of products.

伺服 In servo systems that use resistors for current sampling, the effect of sampled signal quality on current control performance is critical. ADI offers the industry's best performance solutions based on sigma-delta modulators.

位置 Position detection performance is the key to servo control, often using optical encoders and resolvers as position sensors. The conversion of servo control technology from analog to digital has promoted the development of modern servo systems and also met the high requirements for the performance and efficiency of motor control.

☑ From the perspective of prioritizing safety and protection, signal sampling and power device drivers should be isolated. ADI's iCoupler digital isolators meet high voltage safety isolation requirements.

性能 The performance of the IGBT power device drive protection circuit determines the reliability and safety of the product. ADI's power device driver ICs integrate a rich set of protection features to make the design simpler and more reliable.

进行 High-performance vector control and sensorless control with high-performance processors such as DSP.

网络 Network solutions that support multiple motion control and industrial real-time Ethernet protocols.

☑ Using an integrated power factor correction (PFC) controller, it is easier to reduce the current distortion at the power input of the servo system.

é•¿ Long life cycle and high reliability IC products are the first choice for engineers in the design of industrial applications.

转变 It is a general trend to convert ordinary AC induction motors to permanent magnet synchronous motors, requiring system designers to provide more efficient and flexible algorithms.

高性能 High-performance real-time industrial control network for better synchronization of multiple motors.

Value proposition for ADI solutions

For motor control systems, industrial system design requirements are low power consumption and high efficiency. ADI provides a single device and a complete product signal chain to speed up system design; in the signal chain, ADI provides feedback and detection, isolation, The power management, interface, embedded processing and communication products are second to none in terms of performance and quality, and can also reduce costs from the system level. It can be said that ADI's broad portfolio of technologies, including world-class isolators, processors, converters, and mixed-signal front ends, meets engineers' needs for any motor control solution now and in the future. The figure below is the system block diagram and signal chain of the ADI solution.

USB Countdown Timer

Function description

The socket is ordinary converter,with two output 5V2A power USB power supply at the same time,can be very convenient in use electrical appliances and recharge the equipment at the same time,such as digital products like Iphone Ipad,MP3,MP4 etc.The charge apply to full range of international AC output,no-load power consumption less than 0.3W,with short circuit,overload,over-voltage protection,can be convenient for your life and save more energy

Timer Control Time Adgustment

1.Press the power switch 1 time,the 1HOUR LED will light on.The Timer into ON mode,USB and control socket output ON .

2.Continuously press the power switch the LED light on,the Countdown mode and LED light on will cycle change from 1HR,2HR,4HR,6HR,8HR,10HR.

3.Choose you need countdown time mode,the mode LED will lighto on,start countdown until countdown time finish,the control output and USB change to OFF

4.Then the countdown is start,The Time indicate LED will from high to low auto change until Countdown finish off.

Failure analysis:

1.check whether the power supply connection is good

2.check whether the USB cable is loosen
