Servo Driver: The driver has built-in PLC function and many functional modules, including special modules such as pursuit and rotary cutting, 8 digital input points, 6 digital output points, 2 analog output, and the interface of main shaft encoder access, simulation encoder output, etc. It is the best choice for minicomputer. It can omit PLC and support RS232 at the same time. 485, communication support ModbusRTU protocol.
