    multiple preset

    It implements up to 16 speeds via the simple PLC function or combination

    of DI terminal states.

    Onboard PIDIt realizes process-controlled closed loop control system easily.
    Auto voltage


    It can keep constant output voltage automatically when the mains voltage


    Over voltage/

    Over current

    stall Control

    The current and voltage are limited automatically during the running

    process so as to avoid frequent tripping due to over voltage/over current.

    Fast current

    limiting function

    Minimizing over-current fault protect the normal operation of the inverter
    Torque limit and


    It can limit the torque automatically and prevent frequent over current

    tripping during the running process.

    Torque control can be implemented in the CLVC mode.





    Control of asynchronous motor and synchronous motor are implemented

    through the high-performance current vector control technology.

    Power dip ride


    The load feedback energy compensates the voltage reduction so that the

    AC drive can continue to run for a short time.

    Rapid current


    It helps to avoid frequent over current faults of the AC drive.
    Virtual I/OsFive groups of virtual DI/Dos can realize simple logic control.
    Timing controlTime range: 0.0–6500.0 minutes


    Four motors can be switched over via four groups of motor parameters.


    It supports communication via Modbus -RTU, PROFIBUSDP, CAN link

    and CAN open.

    Motor overheat


    The optional I/O extension card enables AI3 to receive the motor

    temperature sensor input (PT100, PT1000) so as to realize motor

    overheat protection.

    Multiple encoder


    It supports various encoders such as differential encoder, open-collector

    encoder, resolver, UVW encoder, and SIN/COS encoder.
