Frequency Converter, Frequency Inverter, Variable Speed Drive (VSD), Variable Frequency Drive(VFD), AC Driver, Main Specifications: Item SpecificationsInputRated voltage and frequencySingle-phase 220V, three-phase 220V, three-phase 380V; 50Hz/60Hz Variable allowable valueVoltage: -20% +20 Voltage unbalance: <3% Frequency: ±5 OutputRated voltage0200V /0380V Frequency range0Hz400Hz Overload capability 150% for 1 min, 180% for 1s, 200% instant protection Main control functionControl modeSpace voltage vector PWM control ; Sensorless vector control (SVC) Frequency accuracy Digital setting: Max frequency ×±0. 01% Analog setting: Max frequency ×±0. 2% Frequency resolutionDigital setting: 0.01Hz Analog setting: Max frequency ×0.1% Torque rise Auto torque rise, manual torque rise 1%30.0% V/F curveThree ways Linear V/F curve, square V/F curve, user self-defining V/F curve Acceleration/deceleration curveOptional time unit (Min/s), the longest: 6000s (settable in the range of 0.13600s). DC braking Be optional during both starting and stopping, the operating frequency: 020Hz,operating voltage level: 020%,operating time: settable within 020s JoggingJogging frequency range: 0.1Hz50.00Hz,jogging acceleration and deceleration time: 0.13600s. Built-in PIDIt is convenient for forming closed loop control system, applicable for course control like pressure and flow, etc.Multi-speed operatingRealize multi-speed running by built-in PLC or control terminal. Weaving wobble frequencyCan get wobble frequency of adjustable central frequency Auto voltage adjustmentWhen main voltage changes, the output voltage may be kept constant by adjusting PWM output (AVR function). Auto energy-saving runningAccording to load condition, V/F curve can be optimized automatically to get the aim of energy-saving running. Auto current limitingLimit in-service current automatically, so as to avoid tripping for fault caused by frequent over current. Sensorless vector control Torsion characteristic150% output of torque at 1Hz, rev accuracy: 0.1% Motor parameters automatic readReading the parameters from motor when completely stop in order to achieve optimal controlling effect. Running functionRunning command passageSetting of operating manual; setting of control terminal; setting of serial port; switching by three ways.
