快速卷帘门常见故障处理方式:


1、问题:按快速门控制箱运行按钮或者遥控按钮,电机不工作不转动


问题原因和解决设施:
 

(1)运行方式设定错误,检查P102是否设定为1;
 

(2)频率指令没给定或频率给定小于启动频率;
 

(3)外围接线错误,检查外围接线;
 

(4)变频器输入端子定义错误,与外围接线不对应,降低环境温度;

4、问题:电机运转方向相反
 

问题原因和解决设施:
 

(1)将变频器输出端子U/V/W任意二相对调;
 

(2)运行控制信号相反,如原来设定正转,现可以设为反转;
 

5、问题:变频器启动,干扰其余装置
 

问题原因和解决设施:
 

(1)降低载波频率;
 

(2)在变频器的电源输入端加装载滤波器;
 

(3)在变频器的电源输出侧加装载滤波器;
 

(4)变频器及电机正确接地;
 

(5)主回线路与其余信号线分开走线;
 

(6)控制线接纳屏蔽线,电缆套上金属管;
 

(7)进线侧,出线制加装磁环。



Common troubleshooting methods of fast shutter door:



1. Problem: Press the fast door control box operation button or remote control button, the motor does not work and does not rotate.



Reasons for the problem and solutions:


(1) Error setting of operation mode, check whether P102 is set to 1;


(2) The frequency instruction is not given or the frequency is given less than the starting frequency;


(3) Error of peripheral wiring, check peripheral wiring;


(4) The definition of input terminal of frequency converter is wrong, which does not correspond to the peripheral wiring. The hard shutter of Beijing Longshengmen Co., Ltd. appeared in Hengda City of Qinhuangdao to reduce the ambient temperature.


2. Problem: Vibration or abnormal noise of fast rolling shutter


Reasons for the problem and solutions:


(1) If the machine is stuck or lubricated poorly, check the mechanical load;


(2) Machinery has resonance phenomenon, adjust carrier wave, change deceleration ratio, avoid resonance frequency, and install shock absorber gasket;


3. Problem: Motor can't run backwards


Reasons for the problem and solutions:


(1) If reversal is prohibited, the prohibition of reversal shall be lifted;


4. Problem: The motor runs in the opposite direction


Reasons for the problem and solutions:


(1) Relatively adjust any two U/V/W output terminals of the converter;


(2) Operating control signal is opposite, if the original setting is positive, it can now be set as reverse;


5. Problem: Inverter startup, interference with other devices


Reasons for the problem and solutions:


(1) Reducing carrier frequency;


(2) Loading a filter at the power input of the converter;


(3) Loading filters on the power output side of the converter;


(4) Correct grounding of frequency converter and motor;


(5) The main circuit is separated from the rest of the signal lines.


(6) Shielding wires are adopted in the control line and metal tubes are sheathed in the cable.


(7) Install magnetic rings on the inlet side and outlet side.
