ABSTRACT:
The present invention imports network communication concepts into a motor and/or motion control system. The motor and/or motion control system is divided into various modules. A preferred configuration includes a motor drive control module, a user command module, and a master control module. The modules are interconnected by a simple hardware bus, such as an RS-485 bus. Communication between the modules is accomplished using a time division protocol.
