Cause Analysis of Common Abnormal Failures of Fast Door Motors

　　The motor is the power guarantee for the fast door. If there is something wrong with the motor, it needs professional personnel to repair it, perhaps to replace the motor. Below, Xinyi fast door manufacturers come to share with you the reasons for common abnormal failures of fast door motors.

　　Fault 1: No display when the motor is powered on.

　　The cause of the failure: the switching power supply of the motor is damaged or the soft charging circuit is damaged, which causes no DC current in the DC circuit of the fast door motor.

　　Fault 2: The motor shows overvoltage or undervoltage.

　　Cause of failure: This failure is usually caused by input phase loss, circuit aging, and circuit board moisture. Find out the voltage, detect the circuit, and replace the damaged device to solve the fault.

　　Fault 3: The no-load output voltage of the motor is normal, and it shows overload or overcurrent after loading.

　　Cause of failure: caused by improper parameter setting or aging of drive circuit or module damage.

　　Fault 4: The output voltage of the motor with no load is normal, and it shows overload or overcurrent after loading.

　　Cause of failure: Improper parameter setting of the fast door motor or aging of the drive circuit, the module is damaged.

　　Fault five: The motor inverter module is damaged.

　　故障原因：快速门电机、电缆出现损坏及驱动电路故障。修复驱动电路，检测驱动波形良好后，开始更换模块。

　　故障六：电机整流模块损坏。

　　故障原因：快速卷帘门电机的电网电压或内部出现短路。

　　快速门厂家提醒大家，任何故障的发生都有一定的原因，快速卷门也是如此，一旦发现异常，先查明原因，再动手处理，如此才能事半功倍!
