Abstract
The present invention relates to a servo driver. It is formed from control plate and power plate, its control plate adopts DSP (digital signal processing) technique and has the interfaces of RS232/485 and TCP/IP for connecting with computer, and its power plate adopts three-phase PWM converter and matches it with correspondent software so as to form the invented digital servo driver. It can be applicable to the control of AC servo motor, DC servo motor, brushless DC motor, induction servomotor and vector induction motor, etc. and can utilize computer networking to implement remote control and remote monitoring.
Description
Technical field
The present invention relates to the drive unit of servomotor.
Background technology
Present servo-driver adopts analog circuit control usually, and a kind of servo-driver is controlled a kind of corresponding servomotor, if change one type of servomotor, then servo-driver will be changed the control corresponding device, can not be general, and also production cost is also high; Have again, can not network, thereby can not Long-distance Control and remote monitoring.
Summary of the invention
The objective of the invention is to use digital technology and software control to solve the existing equipment of prior art can not be general, the deficiency that can not network.
The present invention mainly is made up of control board (1) and power amplifier board (2), see Fig. 1, control board (1) mainly contains two chip blocks, be DSP (Digital Signal Processing) chip and CPLD (FPGA (Field Programmable Gate Array)) chip, in conjunction with digital circuit and software control, produce high-frequency PWM (pulse-width modulation) control signal, power amplification through power amplifier board (2), drive servomotor, and in the software control mode, realize all Electric Machine Control, SERVO CONTROL and motion control, able to programmely flexibly can adapt to various application requirements; Control board (1) also has RS232/485, TCP/IP port, can make the present invention can accept Long-distance Control and remote monitoring by computer networking; Power amplifier board (2) is a supply convertor, under pwm signal control, and through power amplification, single-phase alternating current is become the required three phase mains of suitable servomotor.Control that the responsible pwm power of power amplifier board (2) amplifies and electronic type is dynamically braked, the while also provides the power supply of control board (2).
Because the present invention has adopted with the dsp chip and has been the digital technology of core and is equipped with corresponding software, has realized highly versatile, promptly applicable to the control of AC servo motor, DC servo motor, brshless DC motor, induction servomotor, vectorial induction machine; Cost can reduce about 30%; And can realize Long-distance Control and remote monitoring by computer networking, improve the level of IT application of enterprise.
Description of drawings
Fig. 1 is an electric theory diagram of the present invention, and DSP is a digital signal processing chip among the figure; CPLD is a programmable logic chip.Three pulse-width modulation control signals that the different in width pulse is power controlling plate (2) of control board (1).
Fig. 2 is motion control of the present invention and SERVO CONTROL block diagram.
Embodiment
Also be further described in detail in conjunction with the accompanying drawings below by embodiment.
Embodiment:
The main chip DSP of control board (1) adopts the TMS320F240 of TIX (TI), and the CPLD chip adopts ALTERA EPM7064.Three ports are arranged on the control board (1), be respectively CN1, CN2 and CN3, see accompanying drawing 1, CN1 is computer series connection interface RS232/485, TCP/IP port, be used for the communication between the present invention and computer, provide such as functions such as parameter setting, formula renewal, operation supervise and controls; CN2 is the back coupling port of motor photoelectric encoder; CN3 is major control of the present invention interface, accepts from the servo order of motion control card and the back coupling signal of mechanical system, comprises such as P-pulse order, matching test speed command, numerical digit logic control order, the machinery signals such as back coupling that make zero.The invention provides three kinds of major control patterns, i.e. position control, speed control and moment of torsion control, its motion control and SERVO CONTROL functional-block diagram are seen Fig. 2.SERVO CONTROL software adopts the Easy Tune based on Windows operating system.
Power amplifier board (2) mainly is the three-phase PWM converter, adopt the intelligent power module I PM-060 of MIT, export by power port CN4, because power amplifier board is high voltage, high electric current, and the very strong electromagnetic interference of high frequency switching meeting generation, be the electromagnetic interference source of Mechatronic Systems, so its distribution should be short more good more, simultaneously should be away from control line, power line adopts shielding conductor, to intercept electromagnetic radiation.
Claims (2)
1. servo-driver of forming by control board (1) and power amplifier board (2), it is characterized in that control board (1) mainly contains two chip blocks, be DSP (Digital Signal Processing) chip and CPLD (FPGA (Field Programmable Gate Array)) chip, in conjunction with digital circuit and software control, produce high-frequency PWM (pulse-width modulation) control signal, power amplification through power amplifier board (2) drives servomotor, and realizes all Electric Machine Control, SERVO CONTROL and motion control in the software control mode; Control board (1) also has RS232/485, TCP/IP interface, can be by computer networking.
2. according to the described servo-driver of claim 1, it is characterized in that the dsp chip of described control board (1) adopts the TMS320F240 chip, the CPLD chip adopts ALTERA EPM7064 model.
