The normal spot becomes a spot line (left) by swinging the electric machinery, and if the motor is not swinging, then a dot will be displayed (right).

The analysis of causes:

One. Whether the software section is set correctly

Settings - Scan Correction: 1.25

Process - Scan width: welding system 3-5 and cleaning system 20-150

Home - Indicates Red Light turns on

Two. Check hardware section

1. The power supply of the swing motor is 15V power, we should first measure whether the power supply of the 15V switching power is normal.

2. In addition, the 15V switching power supply is divided into positive and negative, 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 the No. 2 pin GND!

3. (Model SUP20S/T/C) Check whether the interfaces at both ends are inserted in place and whether there are any mistakes on the drive board

4. (Model SUP15S) If the power supply is normal, it is generally caused by a broken circuit. The control box and the motor are powered by a 2-core wire, focusing on checking the 2-core wire of the air plug, and disassembling to see if the circuit is broken

5. （Model SUP15S）When there is no problem with the 2-core wire, check the signal insertion of the 5-core wire, and also disassemble it to see if there is a broken circuit

6. Check whether the rainbow link between the mainboard and the driver is loose or not.

7. When all the above cannot be handled, please replace a motor cable. As to the skill, we can communicate in group.
