Discussion on the priority control mode of motor control

In current industrial automation control systems such as cement production line and slag production line, according to the priority of control authority, two motor control methods are often used: the machine-side priority control method (or the local priority control method) and the central control room priority control method (or the remote priority control method). For the former, it has been familiar and widely used. For the latter, many electricians are very unfamiliar, but there are more and more applications. Based on the author''s application and experience in practical projects, this article focuses on the specific implementation methods and characteristics of the central control priority control method, and gives suggestions for suitable places according to the differences between them.
