Answer 1

Is there a frequency converter that can drive servo motors?

Of course, the common servo motor inverter manufacturers and brands are: ABB, Siemens, Schneider, Yaskawa, Delta, Omron, Hitachi, etc.

Servo motor inverter control - servo motors frequency converter

The steps to solve the problem of using the inverter with servo motor are as follows:

1. First of all, it is necessary to determine the model of frequency converter and servo motor, and the connection between them;

2. Secondly, according to the model of the frequency converter and servo motor, find the corresponding technical data and determine the connection between them;

3. Then, according to the technical data, according to the correct connection method, connect the frequency converter and the servo motor;

BLDC motor with high reliability, low vibration, high efficiency, low noise, energy saving and consumption reduction performance advantages and the implementation of motor energy saving and consumption reduction national mandatory standards, BLDC motor control technology is increasingly mature, semiconductor component manufacturing cost gradually reduced development background, BLDC motor in smart small household appliances, PC, power tools, white goods, servo, sports travel and other downstream terminal fields penetration rate continues to increase, however, BLDC motor substitution effect started late, penetration rate is still low, There is a large room for development with the ceiling of industry penetration.

Servo motor frequency converter

In addition, at present, China's BLDC motor drive chip industry has not yet appeared a full-field competitive strength manufacturer, so it provides a broad space for the development of Yuchuang Semiconductor BLDC motor drive control chip.

Answer 4

Yuchuang Semiconductor has established a two-line parallel product route for display driver chips and power management chips. Since the first HD DDI display driver chip released by Yuchuang Semiconductor, in just two years, Yuchuang Semiconductor has successively mass-produced a number of display driver chips supporting different resolution types in the industry, and the products are applied to smart phones, tablet computers, industrial control security instruments, Internet of Things AIOT smart speakers and other fields, and successfully formed stable cooperation with first-line brand customers, as of 2021, the total shipment of Yuchuang Semiconductor display driver chips has achieved tens of millions of mass production results.

Answer 5

Sinamics S120 is a new drive control system from Siemens that combines V/F, vector control and servo control, and can control not only ordinary three-phase asynchronous motors, but also synchronous motors, torque motors and linear motors. 

Siemens servo motor frequency converter

Its powerful positioning function enables the relative positioning of the feed axis. Siemens S120 inverter is a series of universal and modular products, but also Siemens' powerful low-voltage inverter system, which can drive a variety of low-voltage asynchronous motors, low-voltage synchronous motors and servo motors.

The Siemens S120 inverter integrates two control modes: SERVO and VECTOR. Both have their own advantages and can no longer be mixed within the same CU. This means that only one control mode can be used within a CU.

Servo control applications need precise positioning, need to improve the production cycle, high dynamic response means faster acceleration and deceleration characteristics and better follow-up, generally with upstream motion controllers to achieve position synchronization, cam synchronization, path interpolation and other functions, widely used in all kinds of production machinery, such as packaging, printing, textile, machine tools, robots... and other occasions.

Answer 6

SINAMICS S120 is a high-performance, high-precision drive. The hardware has a modular structure design, easy installation and maintenance; Powerful software features make it suitable for a variety of complex applications.

All low-voltage motors of Siemens, such as asynchronous (inductive) motors as well as synchronous motors, can be dragged. A variety of cooling methods make it more adaptable to various occasions and applications.

Answer 7

ABB brand frequency converters can control servo motors. According to the relevant public information, ABB was formed in 1988 by the merger of Sweden's Asa and Switzerland's Bronbofari and is headquartered in Zurich, Switzerland.

Answer 8

Can AC servo motors be controlled with frequency converters?

Due to the different performance and function of the inverter and servo, the application is not very different, so it is not possible:

　　　　

(1) In the occasion of speed control and torque control, the general frequency converter is not very high, and there are also position feedback signals in the upper position to form a closed loop with frequency conversion for position control, and the accuracy and response are not high. Now some frequency conversions also accept pulse train signals to control the speed, but it seems that the position cannot be directly controlled.

(2) In the occasions with strict position control requirements, only servo can be used, and the response speed of the servo is much greater than the frequency conversion, and some occasions with high requirements for speed accuracy and response are also controlled by servo, and almost all occasions that can be controlled by frequency conversion can be replaced by servo.
