Elevator inverter function

(1), the use of high-performance magnetic beam vector control (FOC) technology, can drive asynchronous motor and permanent magnet synchronous motor, with static self-learning motor parameters and encoder origin offset angle function, easy to use.
(2) Zero speed starting torque can reach 150%, which can prevent the elevator from slipping.
(3) No need for load-bearing compensation, the start zero speed position control mode is adopted to eliminate the start-up sensation.
(4) PDFF control, easy to debug the bandwidth of each band, with 5 sets of S curves, to ensure good comfort.
(5) At the same time, it has a variety of start/stop control timing options, which is convenient for matching various host computer timings.
(6) The control of the external mechanical brake and contactor greatly facilitates the use of customers.
(7), and support UVW, positive residual rotation, communication and other forms of encoder, can detect the encoder disconnection in real time, quick alarm output, to ensure elevator safety.
