Introduction
This product is a stepper/servo motor motion controller based on RS-485+Modbus communication. Its core capability is bidirectional motion control for stepper servo motor pulse modes, such as start, stop, forward rotation, reverse rotation, zero return, top position, absolute position, relative position, etc. It is also equipped with external power interfaces, such as motor power, sensor power, external device power, motor enable, LED indicators, display screens, etc., and supports independent on-off control through instructions.
It is used in various industrial, medical and civil equipment, such as industrial automation production lines, smart agriculture, smart warehousing and logistics, smart buildings and security, laboratory automation and medical equipment, etc.
