MD300 series inverter MD300 series inverter is a high performance simple function of the inverter control mode V / F and the speed sensor vector control of two. Functionality only a simple speed control function, but superior performance, especially under speed sensorless vector control mode, low torque, steady speed precision and excellent dynamic characteristics are widely used in machine tools, wire drawing machine, injection molding machine, lifting machinery, printing machinery and other fields. MD300 series drives are available with expansion cards MD30IN, energy-saving injection molding machine can be used with. ◆ MD300A MD300A series inverter series is based on extensive market research to develop high-performance, general-purpose inverter. This product inherits the advantages of UPM's products, with a V / F and open-loop vector control two control modes, ensure excellent torque characteristics and low frequency dynamic response. Functionally, through market research, customer segmentation summary functional requirements, increased the number of features that make the series truly high-performance drive is a kind of common functions. ◆ MD320 series inverter MD320 series inverter is an outstanding representative of high-performance, multi-purpose inverter; control: speed sensorless vector control, speed sensor vector control, V / F control. Control Object: speed control and torque control of two. Frequency source combination: a wealth of frequency source and switching mode for synchronous control. PID algorithm: advanced PID algorithm, fast response and adaptability. 16 sections of speed control, traverse control is widely used in wire drawing, wire, textiles, chemical fiber, elevators, printing and packaging machinery, fitness machinery, machine tools and other industries. MD320 series inverter has abundant expansion card options, including I / O expansion card, Modbus card, RTU bus card, water supply expansion cards. ◆ MD330 series inverter MD330 tension control specific frequency converter is to increase take-up of high-performance vector control function modules developed on the basis of the drive MD320. MD330 winding integrated rich sound control mode, winding tension control can meet all kinds of situations, the mechanical electrical control system is more simplified. MD330 tension closed-loop and open-loop tension control mode, the user can control the different needs of different external environment and configuration flexibility to choose from, there is a horizontal line speed MD330 winding mode control mode compared to traditional linear velocity closed-loop system is more stable, with some must control winding (unwinding) Line speed occasions model:.
