案例名称: Spinning-frame
说明: I. Technics Introduction The spinning-frame is main spinning machine. The yield and quality of spun yarn comprehensively reflects merits and shortcomings of each working procedure in spinning process. The spinning-frame's production unit is spindle. The yield (kg) per thousand spindle hour is frequently used to measure production-level of spinning-frame. The spinning mill's production scale is represented by total spindles of spinning-frame. The spinning yarn on each spindle would be broken for all kinds of reasons. The end breakage rate is frequently represented by number of broken ends per thousand spindle hour. The end breakage rate affects labour productivity, equipment productivity, spun yarn quality and workshop dust content.The spinning-frame is a machine with the most dissipation energy in spinning. Decreasing end breakage rate and energy saving is a technical level mark of spinning-frame.The inverter is rich in application experience in spinning industry,especially in spinning...

案例名称: Auto tuning
说明: ◆ First step, must disconnected from the load. If the motor can be disconnected from the load, it can select rotation auto-tuning (P9.15=2), or it can select static auto-tuning only.◆ If the inverter power does not match the motor power, select static auto-tuning. after the tuning, manually change the no load current P9.05 to about 40% of the motor rated current P9.04◆ Setting P0.01=5,recover parameter to factory setting◆ Setting motor basic frequency P0.15 according to motor nameplate◆ Setting motor rated voltage P0.12 according to motor nameplate◆ Setting motor pole P9.01 according to motor nameplate◆ Setting motor rated rotation P9.02 according to motor nameplate◆ Setting motor rated power P9.03 according to motor nameplate◆ Setting motor rated current P9.04 according to motor nameplate◆ Setting P9.15=1 and pressure RUN key to perform static auto-tuning◆ Setting P9.15=2 and pressure RUN key to perform static rotating-tuning, if perform rotating-tuning, should be careful because the ...
