The MD310 series frequency converter is a universal compact multifunctional frequency converter that adopts open-loop vector and V/F control methods. With high-performance current vector control technology, asynchronous motor control can be achieved. The MD310 comes standard with an RS485 communication interface, supports Modbus RTU communication, and can be extended with I/O expansion cards and CAN communication expansion cards. The built-in PID can facilitate the implementation of a closed-loop process control system, with a maximum speed of 16 segments.

Small volume - small size, high cost-effectiveness
Overexcitation function - can effectively suppress the rise of bus voltage during deceleration and avoid frequent overvoltage faults
Control application - built-in PID regulator, combined with the selection of frequency given channels, users can easily achieve automatic adjustment of process control, such as constant temperature, constant pressure, tension and other control applications
Swing frequency function - In textile and chemical fiber processing equipment, the use of swing frequency function can improve the uniformity and density of spindle winding
Time sharing control - can store 4 sets of motor parameters, and one frequency converter can control the operation of four motors in time sharing
Timing operation function - the operation time can be set through parameters and analog quantities
Fast bus connection - standard RS485 communication interface, supporting Modbus RTU communication, expandable CANLink, achieving fast bus connection with Huichuan products
Virtual oscilloscope function - supports parameter operation of the frequency converter and virtual oscilloscope function. Through the virtual oscilloscope, graphical monitoring of the internal status of the frequency converter can be achieved
Standard brake unit - users directly connect the brake resistor without external braking, saving costs
