The UCP design started from the customer's requirements for small size, multi-function and high precision, and supports PLC control. Stepping motors and conventional drivers are mostly used for packaging machinery. The speed of the pump can be controlled by pulse to achieve precise filling. Chuangrui's unique control program can support analog control (0-5v 0-10v 4-20mA 0-10KHz) start-stop control, direction control. It also supports RS485 communication protocol. The pump can be better embedded and combined with the customer's equipment.
