The product was adopted with typical V/F control technology, zero-speed sensor control technology, closed loop vector control and torque control technology, combined with the characteristics of domestic application, further strengthening the product reliability, environmental adaptability and design for customer and the industry, perfectly satisfying a variety of heavy load driven application requirements.Feature and Advantages1. High -efficient & energy saving operation2. Fast Dynamic ResponseAdvanced motor control can also quickly response to load change without PG Card.3. Smooth tracking startAt any time, smooth start can be perfectly achieved without impacting the rotating motor.4. Powerful grid adaptabilityAutomatic voltage adjustment function: when the grid voltage changes, the output voltage can be automatically kept constant. In the case of sudden loss of electricity, unique non-blackout function can keep VFD running. 5. Stable operation with low frequency and high torque.Dynamic calcultion of IGBT internal temperature ensures that the IGBT module operates with the temperture limits, improving reliablity of the module.6. Positive-reverse switchWhen positive-reserve motor switch to the zero-speed, the phase of current has no change or oscillation, and speed has no ripple.7. Papid acceleration0.1s full load acclleration with fast torque response and low speed overshoot.8. IGBT temperature protection curveDynamic calculation of IGBT internal temperature ensures that the IGBT module operates within the temperature limites, improving railiability of the module.Intimate application function* PID control dedicated menu to set PID parameters, calculate inside the VFD, without independent external regulator option. * DC braking before operation: when the rotating direction of motor during free sliding is uncertain, DC braking automatically stop the motor before starting.* For the square torque load of fan and water pump, high performance excitation control can make the motor run at the optimal efficiency point and achieve optimal energy saving effect. * Master-slave control* Flexible connectionMaster drive is the speed control, and slave drive is the speed control. Small speed difference is allowed between slave drive and master drive.Speed drive receiving the speed signal from the master drive is implemented with drop.* Rigid connectionMaster drive is the speed control and slave drive is the torque control. Speed difference is not allowed between slave drive and master drive.The torque signal of the master drive is transmitted to the slave drive VFD with high speed and accuracy in the following ways:Profibus-DP communication connection realizes master-slave control (applicable to high-accuracy master-slave control).Analog input and output outlet(master -M0/M1, slave-A01/A1) connection realizes master-slave control(applicable to master-slave control with low speed and low control accuracy)AS450 series VFD technical parametersStable running 40ºC, heavy duty loadingDimensionVFD ModelAS450Rated input current (A)Rated output current (A)Adaptive motor(Kw)Overload 120% (1min)Output current (A)4T07P518177.525.5A24T001126251136.54T011535331547.5A34T18P5434118.559.54T012247452267.54T003063603090A44T00377370371054T0045959145136.5A54T0055117112551684T007515615075225A64T009018718090270A74T01102242161103244T0132269260132390A84T01603123021604514T01853833701855554T02004013902005854T02204384262206394T0250492480250720A94T02805325202807804T03156136003159004T0355663650355975Dimension tableSpecificationHeight(mm)Width (mm)Depth (mm)Weight (kg)A13001601624.5A23792221828A341423218210.3A453033028829.5A561033031038A675043035079.5A780043035081A8880500350112.5A91030630370170A101189852431280A111359852431310
