Abstract

The invention discloses an Ethernet-based motor controller and control system. The motor controller comprises a communication interface circuit which comprises an Ethernet interface and a field bus interface, a closed loop feedback interface circuit used for receiving load feedback information from one or more motors, a motor control interface circuit used for sending control information for one or more motors, and a control circuit connected with the communication interface circuit, closed loop feedback interface circuit and motor control interface circuit and used for controlling the operation of each interface circuit and processing the information received by the communication interface circuit and closed loop feedback interface circuit, and the communication interface circuit and motor control interface circuit send the processed result to control the running of one or more motors. The Ethernet-based motor controller is capable of providing multi-axis control, closed loop feedback and Ethernet-based remote control and also providing local or cascade control.

Description

technical field [0001] Exemplary embodiments of the present invention relate generally to motor control, and more particularly to an Ethernet-based motor controller and control system. Background technique [0002] Motor controllers currently developed and sold, such as two-phase hybrid stepper motor controllers, generally use fieldbus interfaces such as RS-232, RS-485, USB, and CAN to provide single-axis control mode and no closed-loop feedback interface. This motor controller cannot implement direct Ethernet-based remote control and cannot meet the requirements of multi-axis control applications. In addition, since there is no closed-loop feedback interface, an additional feedback interface needs to be added, resulting in a complex structure and increased cost. [0003] There is a need for a motor controller that can provide multi-axis control, closed-loop feedback, and remote control based on Ethernet technology, while also providing local or cascaded control.
