[embodiment]
See also Fig. 1, it is the overall structure schematic diagram of a kind of textile machine dedicated servo controller described in the utility model, comprise Switching Power Supply, master board, display floater, motor-driven plate, servomotor, described master board connects Switching Power Supply, display floater, servomotor and motor-driven plate respectively, and described motor-driven plate connects Switching Power Supply and servomotor.Wherein, Switching Power Supply is used to provide the voltage of continous-stable to export to module and components and parts power supplies such as master board, display floater, motor-driven plate; Described master board comprises CPLD chip, single-chip microcomputer and servomotor special chip, described single-chip microcomputer connects CPLD chip and servomotor special chip respectively, described CPLD chip connects display floater and host computer, described single-chip microcomputer is connected servomotor with the servomotor special chip, described CPLD chip adopts programmable logic device EPM240T100C5, described single-chip microcomputer adopts 16 single-chip microcomputer dSPIC33FJ64MC506, and described servomotor special chip adopts IRMCK201.Master board is used for realizing the various computings and the algorithm of Electric Machine Control, master board is realized comprising various algorithms and control to servomotor: electric current loop, speed ring, position ring, orthogonal frequency division, host computer communication scheduling algorithm and control by 16 single-chip microcomputer dSPIC33FJ64MC506 of main control chip Microchip, servomotor special integrated circuit IRMCK201 and programmable logic device EPM240T100C5.Main control chip dSPIC33FJ64MC506 realizes data wire and the multiplexing annexation of address wire by 8 bus forms and servomotor special integrated circuit IRMCK201, realization is to the various algorithms of servomotor and the parameter monitoring of servomotor, actuating signal is passed through high speed photo coupling isolation drive servomotor, and by 16 bus forms and EPM240T100C5 realization data wire and the multiplexing annexation of address wire, give CPLD the needs content displayed, CPLD gives display floater displaying contents immediately and shows, receive the button operation of display floater simultaneously, the button operation value is fed back to single-chip microcomputer; Display floater is mainly used in and realizes user interface, shows that current motor status and parameter show, the user can change and check the moving situation and the parameter setting of motor at any time by the button operation to display floater; The motor-driven plate utilizes high speed photo coupling to isolate output driven by servomotor signal; Servomotor receives the drive signal of motor-driven plate, realizes control and High Accuracy Control in real time.
Its operation principle and step are as follows: powered on moment, single-chip microcomputer is configured servomotor special integrated circuit IRMCK201, waits for the host computer handshake then.The host computer handshake is effective, host computer can position operation to servo controller, by pulse signal and direction signal servomotor positioning requirements and rotating speed are required to send to servo controller, servo controller carries out corresponding actions to motor immediately, simultaneously fractional frequency signal is sent to host computer, and monitor DC bus-bar voltage in real time, if it is too high to detect busbar voltage in the process, single-chip microcomputer is exported brake signal immediately, voltage consumption is realized the effect of step-down on brake resistance, thereby play the effect of protection servo controller; If faults such as IPM, servomotor quits work at once in the process, and fault-signal by sending host computer to; Also can operate, realize operations such as the parameter modification of servo controller and servomotor crawls by display floater.
