DEVICE FOR CONTROLLING MOTOR THROUGH CONTROLLER AREA NETWORK

摘要

PURPOSE: A device for controlling motor through a CAN(controller area network) is provided to control a variety of motor flexibly by dividing a motor control into a DSP(digital signal processor)/CAN core module and a motor driving module. CONSTITUTION: A DSP/CAN core module(A) consists of a DSP(10), a program RAM(random access memory)(16) which records programs necessary to a motor control, a data RAM(18) which records data necessary to the motor control, a CAN driver(12) and an RS232C driver(14) which connect the DSP(10) respectively with a CAN and with an RS232C, and an MAC(medium access control) ID(identification) selection switch(20) which indicates a node by a binary number. A motor driving module(B) consists of a separation power transformer(30) which transforms a main power into each separated power for communication/motor/processor, a driving output(34) which outputs a power, an encoder input(38) which inputs a code into an encoder(32), and a digital signal converter(36).
