Embodiment

[0010] The main chip DSP of the control board (1) adopts TMS320F240 of Texas Instruments (TI), and the CPLD chip adopts ALTERA EPM7064. There are three ports on the control board (1), namely CN1, CN2, and CN3, see attached figure 1 , CN1 is a computer serial interface RS232 / 485, TCP / IP port, used for communication between the present invention and a computer, providing functions such as parameter setting, program update, operation monitoring, etc.; CN2 is the feedback port of the motor photoelectric encoder; CN3 is the main control interface of the present invention. It accepts servo commands from the motion control card and feedback signals from the mechanical system, including signals such as position pulse commands, analog speed commands, digital logic control commands, and mechanical zero feedback. The present invention provides three main control modes, namely position control, speed control and torque control. The function block diagram of its motion control and servo contr...

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 [0001] The invention relates to a drive device of a servo motor. Background technique [0002] The current servo drives are usually controlled by analog circuits. One type of servo drive controls a corresponding servo motor. If you change a type of servo motor, the servo drive needs to replace the corresponding control device, which is not universal, and the production cost is also high; Furthermore, it cannot be connected to the Internet, and therefore cannot be remotely controlled and monitored. Summary of the invention [0003] The purpose of the present invention is to use digital technology and software control to solve the problems that the existing equipment cannot be universal and cannot be networked. [0004] The present invention is mainly composed of control board (1) and power board (2), see figure 1 , The control board (1) mainly has two chips, namely DSP (digital signal processing) chip and CPLD (programmable logic) chip, combined with digital circ...
