Full digitalized distributed intelligent servo driver

Abstract

The invention discloses a full digitalized distributed intelligent servo driver which adopts a full digitalized DSP (Digital Signal Processor) + FPGA (Field Programmable Gate Array) structure. The intelligent servo driver provided by the invention integrates the functions of motion control, motor control and a simple PLC (Programmable Logic Controller) and can conveniently construct a motion control system without an upper computer motion controller (card). The intelligent servo driver can be used for controlling and driving a direct current brush (brushless) motor, an alternating current servo motor and a linear motor only through software configuration without changing hardware. The intelligent servo driver can realize the following operation modes: A. an RS232 network control mode; B. an RS485 distributed network control mode; C. an independent driver running mode without the upper computer; D. a pulse command running mode; and E. an analog signal running mode. The servo driver provided in the invention adopts a modularized structure, the same control module can be matched with driving modules of different power levels to form intelligent servo driving systems of different power levels. By utilizing the full digitalized distributed intelligent servo driver, a motion control system with the advantages of low cost, flexible system configuration, simpleness and convenience for operation, reliable performance and convenience of maintenance can be realized.

Description

technical field [0001] The invention relates to a servo driver with multiple functions, in particular to a novel all-digital distributed intelligent servo motor driver capable of driving multiple motors and having multiple operating modes. Background technique [0002] With the increasingly close combination of information technology and mechanical devices and power equipment, servo drive technology has developed rapidly. The role of China's manufacturing powerhouse clearly outlines the bright future of the rapid development of industrial machinery, and the wave of upgrading the automation of industrial machinery has also played a powerful role in boosting the rapid development of servo drive technology and the market. [0003] Since the development of servo drive technology, a large number of special or general motion control and motor drive systems have been developed. But in these systems, the control function and driving function of the motion control system are usually...

Problems solved by technology

[0007] 1). Complex system connection

[0008] The separate structure of the driver and the controller not only increases the complexity of the connection of the motion control system, reduces the reliability and performance of the system, but also increases the cost of the system, and the control performance of the system will also be affected;

[0009] 2). Poor system scalability

[0010] Motion controllers or control cards generally have connection restrictions on the number of control axes, so the scalability of the number of system control axes is poor, which brings certain difficulties to the increase in the number of system control axes;

[0011] 3). Single function

[0012] Such drives usually require the cooperation of the motion controller (card) to work, and the drive does not have the function of running independently from the controller; the connection signal between the drive and the controller is realized by pulse or analog signal, and does not have a more Advanced network function; the controller (card) can not get more parameters and information about the internal drive;

[0013] 4). Can only drive a single type of motor
