    55KW 3 Phase 75 Hp Variable Frequency Drive RS485 for Tunnel Fan


    Sea-worthy Wooden Case Packaged 55KW 3Phase VFD Inverter For Tunnel Fan




    Technical characteristics

    Drive motor type:Ac asynchronous motor, Ac permanent magnet synchronous motor

    Four control modes:PG vector control(FVC), PG-free vector control(SVC),

    V / F control, Torque control

    Speed control range:PG vector control(FVC)1:1000

    PG- free vector control(SVC)1:200

    V / F control 1:50

    Speed control accuracy:PG vector control (FVC)±0.2%

    PG- free vector control (SVC)±0.5%

    Starting torque:PG vector control(FVC):180 % rated torque/0.01Hz

    PG- free vector control (SVC)150% rated torque/0.25Hz

    Torque control accuracy:PG vector control (FVC)±5%

    PG- free vector control (SVC)±8%

    Multi-motor switching: Two groups of motor parameters can realize the switching control of the two motors.

    Motor overheating protection:Optional IO expansion card, analog A / 3 can accept input from motor temperature sensor

    Supports multiple encoders:Supports differential, open collector, uvw, rotary transformer, sine and cosine encoder

    Torque limitation and control: the "excavator" feature, automatically limits the torque during operation to prevent frequent overcurrent trips. Closed loop mode can realize torque control.

    Accelerate/Decelerate curveLine or S-curve Acc/Dec mode, four kinds of Acc/Dec time Range
    of Acc/Dec Time0.0~65000.00s.
    DC brakeDC brake frequency: 0.00Hz to Maximum frequency
    brake time: 0.0 to 36.0s
    brake current value: 0.0 to 100%
    Simple PLC, Multi-speed16-speed operating through built-in PLC or control terminal
    Built-in PIDClose loop control system can be formed easily by using PID
    Automatic voltage
    regulating (AVR)
    Output voltage is regulated when voltage of the power network changes
    Overvoltage and over current
    stall control
    During operation automatically limits the inverter output current
    and bus voltage, to prevent fan over current and overvoltage trip.
    Rapid current limiting
    function
    Minimizing flow failures, protect the normal operation of the inverter
    Instantaneous stop non-stopLoad feedback energy compensation voltage is reduced and continues to maintain a short time when change is momentarily interrupted.
    Speed tracking startFor high-speed rotation of the motor speed identification, impact-
    free smooth start
    Rapid current limitRapid software and hardware limiting technology to avoid
    frequent converter over current fault.
    Virtual IOFive sets of virtual DO, five sets of virtual DI, enables easy logic control.
    Timing ControlTiming control: set the time range 0.0Min~6500.0Hour
    Multi-motor
    switch
    Two independent motor parameters, enabling two motors switching control
    Bus SupportTwo independent Modbus communication, CAN-Link
    Command sourceGiven the control panel, control terminal, serial communication port given. It
    can be switched by a variety of ways.
    Torque boostAuto Torque boost Manual Torque boost ; 0.1%~30.0%.
