Optical absolute encoder CAN bus interface！

In these practical application of the control system due to the sub-system sensor and detector output data structure is different from the absolute photoelectric shaft encoder will use different internal data communication, mainly RS232, RS485 / 488 serial port, parallel port, etc. . However, in the specific project applications, the above-mentioned communication methods are often subject to transmission distance, communication speed and other restrictions. In recent years, the rapid development of serial communication, there have been a variety of control systems in the form of field bus, CAN bus is one of the most widely used, it is the controller LAN bus short, is an effective support for distributed control and real-time control Of the serial communication network. As CAN bus high-performance, high reliability and unique design, has become the most popular at home and abroad and the highest real-time field bus. The development of internal communication in the control system makes the encoder used to measure the angular displacement and angular velocity provide the CAN bus interface to meet the fieldbus design requirements of the whole control system
