Solution | Poor contact of main power supply, damage of DC power supply, control board failure, motor driver failure, mechanical failure. The operator can solve it step by step.
Specific inspection methods:
1. Observe the indicator light on the visual inspection machine, observe the fault location, the main power switch indicator light is not on, check whether the input power supply is in poor contact or the power fuse is blown, and whether the main board LED light is not on. On or the control panel does not display, check whether the DC 5V, 3, 3V power output is normal, and the motor drive indicator is not on? Check whether the power output is normal. When checking whether the power supply is normal, disconnect any output lead of the power supply for testing to determine whether it is the power supply or the power supply element.
2. Check whether all displays are normal. If you can hear an obvious buzzing sound, it must be a mechanical fault. Check whether the trolley and beam are smooth and whether there are obstacles. See if there is anything else blocking it.
3. Check whether the motor shaft is separated and whether the synchronous wheel is loose.
4. Check whether the wire or plug connecting the drive block (device) on the main board, power supply and plug are in good contact.
5. Check whether the wiring connector from the drive block (equipment) to the motor is disconnected. The 18-core wire from the main board to the small board is damaged. Whether there are any images not inserted.
6. Check whether the parameter setting is correct. The parameters on the left are the same. If there are differences, correct them and write them into the machine.
