14 common fault solutions for scanning galvanometer and laser galvanometer

1. Trouble phenomenon: The driver board has no indication or the driver board smokes when it is started for the first time
Reason: The power is not connected or the polarity of the power is reversed;
Solution: Check whether the power supply wiring is correct.

2. Failure phenomenon: the red light on the drive board is always on;
Reason: bad contact between motor and drive board;
Solution: Check whether the connection between the motor and the drive board is firm.

3. Trouble phenomenon: After starting, the red light is on for a long time and there is a clicking sound;
Reason: limit protection occurred;
Solution: Check the input signal to see if the input signal amplitude is too large. If the input signal is normal, please contact our company.

4. Trouble phenomenon: The motor has a whistling sound after starting, and the motor heats up;
Reason: Whether the lens is firm;
Solution: Return to our company if the lens is loose.

3D galvo scanner company China,Carmanhaas offer 3D scanning system 1064nm Fiber Laser 3D Dynamic Galvanometer Scanner Controller for marking and engraving includes multiple pieces of lenses;

5. Failure phenomenon: Whether the connection between the sensor and the motor is intact;
Solution: Check the connection, if the connection is intact, please contact our company.

6. Failure phenomenon: the marking chart forms a straight line;
Reason: One axis of the galvanometer is not working;
Solution: Check whether the connections between the motor and the drive board, the D/A card output signal line and the drive board, and the power supply and the drive board are firmly in contact.

7. Trouble phenomenon: the marking line has wavy lines;
Reason: there is a problem with grounding;
Solution: Check whether the ground wire is well connected.

8. Trouble phenomenon: there is a strong interference source around;

solution: check whether there is a strong interference source around.

9. Fault phenomenon: poor anti-interference ability of control card;
Solution: Check the position signal output of the control card.

10. Failure phenomenon: The motor is noisy during the working process;
Reason: There is interference around;
Solution: Please check whether there are large interference devices around by yourself.

11. Failure phenomenon: the square is a diamond;
Reason: light path deviation;
Solution: Adjust the optical path, but still cannot replace the galvanometer.

12. Failure phenomenon: the marking range does not meet the requirements;
Reason: The position signal ratio is incorrect;
Solution: First adjust the scale factor in the software. If it is not possible to adjust the scan range adjustment potentiometer on the drive board.

13. Trouble phenomenon: The laser energy becomes low or there is no laser output;
Reason: the lens film is damaged or the lens is broken;
Solution: Check the status of the lens.

14. Failure phenomenon: missing points when marking;
Reason: The laser energy is unstable or there is a pause during the pedaling process;
Solution: Repeat the test several times to see if the phenomenon still exists. If the position is different each time, please check the control system; if the position is the same each time, change the galvanometer to test.
