Welding joint problem handling: the motor does not swing.

正常光斑通过摆动电机变成一条光斑线（左），如果当电机不摆动了，那么就会显示一个点出来（右）

The normal light spot becomes a light spot line (left) by swinging the motor. If the motor stops swinging, a spot will be displayed (right).

二.硬件部分检查（首次安装）

1.摆动电机的供电为15V电源供电，我们应首先测量15V开关电源的供电是否正常。另外，15V开关电源分正负，错误的接线也会致使电机不工作，V1接15V+，V2接15V-，15V开关电源上的任意COM接2号脚GND！（检测页面如图显示则为准确）

2. Hardware inspection (first installation)

1. The power supply of the swing motor is 15V power supply. We should first measure whether the power supply of the 15V switching power supply is normal. In addition, the 15V switching power supply is divided into positive and negative, and the wrong wiring will also cause the motor not to work. V1 is connected to 15V+, V2 is connected to 15V-, and any COM on the 15V switching power supply is connected to Pin 2 GND! (The detection page is accurate as shown in the figure)

2.（型号SUP20/1S/T/C）检查连接线的两接口是否插到位和驱动板上位置有没有插错，并且主板与驱动的彩虹链接线是否松动

2. (model SUP20/1S/T/C) Check whether the two connectors of the connecting cable are inserted in place and the position on the driver board is wrong, and whether the rainbow link line between the motherboard and the driver is loose.

3.（型号SUP20/1S/T/C）主板与驱动的彩虹链接线是否松动，驱动的灯是否常亮

3. (model SUP20/1S/T/C) Whether the rainbow link line between the motherboard and the driver is loose and whether the driver's light is always on.

4.（型号SUP20/1S/T/C）检查枪头下面的黑色电机线航插头有无松动

4. (model SUP20/1S/T/C) Check whether the black motor cable plug under the gun head is loose.

三.硬件部分检查（使用一段时间的设备）

1.(SUP15S)如果电源正常，那一般都是断路导致，控制盒和电机通过一根2芯线供电，重点检查2芯线的航插，拆开看是否断路

2.(SUP15S)当2芯线没有问题的时候，检查5芯线的信号航插，也是拆开看是否有断路

3.1电路部分的检查，测量各端口的电压是否正常.以下务必断电拔插！

主控板的插口，负责给驱动板供电，主要测量9-13和22-25各端口的电压，如图所示

3. Hardware part inspection (equipment used for a period of time)

①(SUP15S) If the power supply is normal, it is usually caused by an open circuit. The control box and the motor are powered by a 2-core wire. It is important to check the aerial plug of the 2-core wire and take it apart to see if it is open.

②(SUP15S) When there is no problem with the 2-core wire, check the signal aerial plug of the 5-core wire, that is, take it apart to see if there is an open circuit.

③.1 Check the circuit part and measure whether the voltage of each port is normal. Be sure to power off and plug in the following!

The socket of the main control board is responsible for supplying power to the driving board, and mainly measures the voltage of each port of 9-13 and 22-25, as shown in the figure.

3.2驱动板插口，（工艺里面摆动速度设置60，宽度给3mm）然后主要测量7/8脚的电压值，6V-15V之间

③.2 Drive the socket of the board (the swing speed is set to 60 and the width is 3mm in the process) and then mainly measure the voltage value of 7/8 pins, which is between 6V and 15V.

3.3电机尾部插头下面一排的1/3脚两芯线（等同上图的7/8脚电压）

③.3 One-third pin and two-core wires in a row below the motor tail plug (equivalent to 7/8 pin voltage in the above figure)
