The hard turbine fast door adopts a dedicated control system, the core is a DSP processing chip, and the system can better control the opening height of the door body by receiving the SEJ motor encoder signal:

　　①The hard turbine fast door system has the function of displaying the fault code through the LED tube;

　　②Steering protection: when the motor drive line is connected incorrectly, the controller will report an error directly, and the door will stop moving;

　　③The torque loop, position loop and speed loop of the special system for hard turbine fast door are fully closed;

　　④The system has its own braking function, and the motor can be stopped at the maximum position without external electromagnetic brake pads, so that when the door body stops at the limit position, it is not bad at all;

　　⑤ The memory function of the hard turbine fast door after power failure, after manual operation after power failure, it can be reset to work directly after power on, no need to adjust again.

　　⑥hard turbine fast door motor overload and overcurrent protection.

　　The hard turbine fast doorr can prevent outsiders from intruding while resisting weather changes, and can cut off indoor and outdoor air convection, so it is an economical choice for frequent entry and exit passages, and it is a better industrial energy saving and consumption reduction.
