What should you do when meet these common faults of fiber laser cutter-Charles

Like people, sometimes fiber laser cutter also don’t work , but most of problems is commo faults.

If you also have same problems on your fiber laser cutter, XT Laser bring you to learn what you need to check, then find the solutions.

1.Cutting head of fiber laser cutter

A) Capacitance value turns to 0

It’s necessary to check whether  ceramic ring and nozzle are dirty and blocked.

B) Alarm after touching board

Necessary to inspect whether the connection of radio frequency line is normal and whether clamp ring becomes flexible

C) Calibration abnormality

Should inspect whether encoder line becomes flexible and whether oxidization happens to the interface

2.Servo motor of fiber laser cutter

A) 320 regenerative overloading

Regenerative energy exceeds capacity of regenerative resistance. It’s necessary to inspect whether resistance short connection is normal or circumscribed resistance arises

B) 410 undervoltage. Main circuit power supply part in the servo unit is inspected to be undervoltage, It’s necessary to inspect servo voltage fluctuation scope is exceede, too

C) 520 vibration alarm

It’s necessary to check abnormal sound of the motor and motor speed at the time of running fiber laser cutter.

Keeping lower motor speed or speed ring gain (Pn100).

Necessary to inspect whether the value of rotation inertia ratio exceeds actual value or changes a lot. It’s necessary to correctly set rotation inertia ratio (Pn103)

D) 710 instantaneous maximum load and 720 continuous maximum load

Jinan Xintian Technology Co., Ltd.-Operation Manual for Fiber Laser Lath Cutter

In case of the motor failing to be actuated due to mechanical factor, resulting in too large load at thetime of running. It’s necessary to inspect whether foreign matter happens to rack and guide rail as well as running speed of the motor.

E) F10 Power supply phase shortage

When the power supply of main circuit is in the state of ON and one phase from R, S and T phases is under the state of low voltage for above 1s

It’s necessary to inspect whether power supply wiring is correct and as well as whether each voltage of power supply equilibrates.

F) 101 motor overcurrent detection (current exceeding allowable current passes through the motor) yet

It’s necessary to inspect whether cable wiring for main circuit cable is wrong or undergoes bad contact.

Inspecting short circuit or earth short circuit happens in the servo motor.

To inspect short circuit or earth short circuit happens in the servo unit.

It’s necessary to inspect high load borne by the servo motor at the time of stoppage or low-speed running.

It’s necessary to confirm whether short circuit happens between UVW phases of servo motor connection terminal of servo unit as well as between UVW and ground connection.

G) 400 overvoltage (main circuit power supply part in the servo unit is detected to be of overvoltage)

Check the voltage of power supply. It’s necessary to improve power supply situation as well as set surge suppressor and then connect servo unit power supply anew. In case of alarm still arising, it’s possible that failure happens to servo unit. It’s necessary to replace servo unit

H) 510 supervelocity (motor speed exceeds the highest speed)

To check error of U, V and W phases of motor wiring and confirm wiring of servo motor, too

It’s necessary to inspect whether motor speed exceeds the highest speed. And lower speed command input gain and adjust servo gain or operating conditions.

I) 740 impulse current restricts resistance overloading, also

It’s necessary to inspect allowable times of exceeding impulse current restriction resistance at the time of main circuit power is ON/OFF as well as lower ON/OFF frequency of main circuit power.

J) 810 Encoder backup alarm

It’s necessary to inspect encoder connection as well as carry out setting of encoder.

Also it’s necessary to inspect whether battery of encoder connector as well as connector status are correct

K) C90 encoder communication fault

Also it’s necessary to inspect the state of connector for encoder. It’s necessary to insert the connector for encoder anew and confirm encoder wiring.

Environmental influence, improvement of usage environment and changing cable. In case of not improved, it’s necessary to replace servo unit.
