| 摘要 |
A motor controlling serial communication device includes an upper controller (1) having a first IC (3) and a first connector (2), and motor drivers (10;20,30) having second ICs (13,23,33), second connectors and third (11,12,21,22,31,32) connectors. First cables (14,24,34) and second cables (40) are used for coupling the upper controller to the motor drivers, so that a daisy-chain connection is formed. <IMAGE>
