Abstract
A motor network control system is provided which is capable of reducing the wiring length of a power cable and in which upon replacement of a motor or an inverter of a specific motor unit, no adverse influence is exerted on the other motor units. A power cable 7 and a communication cable 8 connecting between a plurality of motor units 30a-30c, each of which includes a motor 4, an inverter 5 and a communication part 6, extend successively from a power supply 1 and a network control computer 2, respectively, to the respective motor units 30a-30c in such a manner that the motor units are connected with each other in a cascade manner from a preceding one to a following one. In addition, each of the motor units includes a connection board 11 on which an inverter 5 and a communication part 6 are installed. The power cable 7 and the communication cable 8 are connected with the respective inverters and the respective communication parts through connection terminal blocks, respectively, each of which includes a cable connector for connecting the cables from a preceding motor unit and the cables to a following motor with each other, and a terminal block fixture for detachably fixing the asso…
