    G type: 150% Rated current 60s, 180% Rated current 3s;P type: 120% Rated current 60s, 150% Rated current 3s

    Torque hoistingAutomatic torque boost ; Manual torque boost 0.1%~30%
    V/F CurveThree ways: linear, multipoint, N type, V/F curve(1.2 power, 1.4 power, 1.6 power, 1.8 power, 2 power)
    V/F SeparationTwo ways: the separation, half part

    Acceleration /deceleration curve 

    A straight line or S curve deceleration mode. Four kinds of deceleration time, deceleration time range 0~6500s
    DC braking

    DC brake frequency: 0Hz~maximum frequency ; braking time 0s~100s ; braking action current value 0%~100%    

    JOG control JOG frequency range: 0Hz~50Hz ; JOG dynamic and deceleration time: 0s~6500s
    Simple PLC, Multi-velocity runThrough the built in PLC or control terminal at most 16 preset speed operation
    Built-in PIDEasy to realize process control with PID fuction
    Adjust the AVR automatic voltageWhen grid voltage change, can automatically maintain a constant output voltage
    Overload/overcurrent/stall control

    Current automatic voltage limit automatically during the operation, to prevent frequent trip through the pressure

    Rapid current-limitingCurrent- limiting to reduce the over current fault,protect the normal operation of the inverter
    Torque limit and controlCharacteristics: the torque limit automatically during running, prevent over current trip frequently, the torque control closed-loop vector model is achieved

    Support for multiple PG card 

    Support the rotating transformer, differential, open collector, is cosine PG card, etc
    The superior performanceWith excellent performance of current vector control technology to realize asynchronous motor and synchronous motor control
    Instantaneous stop constantly Instantaneous power failure through load feedback energy compensation voltage is reduced, maintain frequency converter in a short period of time to continue running
    Aapid current limitingAvoid the over current of VFD frequent flow of failure
    Timing control Timing control function,the setting time range 0min~6500min
    Communication ssupportSupport Modbus (standard), Profibus-DP (optional), CAN (optional)
    RUN command channel   Keyboard is given, the control terminal, given serial commumication Port, given can switch through a variety of ways
    Frequency sourceA variety of frequency source: digital given, analog voltage, given analog current, pulsegiven, RS485 for a setting, can switch through a variety of ways
    Auxiliary frequency sourceTen kinds of auxiliary frequency source flexible rdalization of auxiliary frequency trimming/ frequency synthesis
    Input terminal line 8 digital input terminals, one support up to 100KHz high-speed pulse input, 2 analog inputs, 1 support only 0~10V input voltage; 1 support 0~10V input vlotage or 4 20mA input
    Output terminal line
