Abstract
According to the servomotor drive control system of the invention, a processing section and a servomotor are arranged at physically separate locations. Data are exchanged via a data bus between a main CPU, which performs input data processing and sequence processing, and the processing section. As a result, servomotor drive commands and feedback data can be transferred at high speed without requiring a special interface device, and an arithmetic circuit section is separated from the environment in which the servomotor is installed.
