 This manual required with the "MD320 User Manual" for use. This manual describes only the tension control and coil part of other basic features, please refer to "MD320 User Manual." 

 When the tension control mode selected is invalid, the function of the inverter is identical with the MD320. 

 Tension control Huichuan MD330 MD320 special frequency converter is based on the increase in the functional modules developed by winding high-performance vector control inverter. MD330 integrated rich sound winding control mode, to meet a variety of situations winding tension control, so that the mechanical electrical control system is more simplified.
