what is hypertherm cnc plasma cutting machine troubleshooting

Fault 1: during normal operation, the hypertherm cnc plasma cutting machine suddenly stops working.

Troubleshooting:

1) stop at the same location each time.

Failure analysis:

A. machining problem

B. CNC system software has problems

Solution: send the program back to the company and analyze it by the designer.

2) when the system is shut down, the system operates normally, while cutting or stopping is only one axis movement.

Failure analysis:

A. motor block

B. running motor fault

Solution: check whether the machine is jammed and whether the hypertherm cnc plasma cutting machine tool is stationary.

3) When the machine stops, the system works, the cutting gun moves or does not move in a certain direction, and press any key (especially the pause key) does not work.

Failure analysis: machine tool is disturbed and crashed.

Solution:

A eliminate interference, pay attention to plasma power and machine tool shell common ground;

B motor (old system) plus isolation board;

C flame mode, cut the oxygen switch solenoid valve to add arc treatment.

Fault 2: motor not running

Troubleshooting:

1) check whether the system line is loose or falling off.

2) check whether the driver displays the alarm correctly and whether the setting is correct.

3) Check whether the starting speed is zero or too high, whether the timing time is too short, whether the electronic gear or pulse equivalent is zero is not appropriate.

4) single axis failure. If you have the same type, you can replace the components of the malfunction type, remove the trouble and find out the problem.

Fault 3: slow system response

Troubleshooting:

1) Check whether the output voltage of the supply voltage switching power supply is within the allowable range to adjust the output voltage of the switching power supply or to replace the switching power supply.

2) the system parameters may not be correct.

Fault 4: limit alarm on startup.

Troubleshooting:

1 (W + - W) Check whether the limit switch is working properly, and whether the connecting wire is defective or missing.

(2) (Y + & gt; S) check whether the current coordinate value of the system is too large, whether it exceeds the software limit value, check whether the software limit value setting is too small to modify to the normal range.

3) Push the external limit switch under the system diagnostic interface to check whether the current coordinate value of the system is too large, whether it exceeds the software limit value, and whether the software limit value is too small.

Fault 5: failure of key or incorrect key value.

Troubleshooting:

1) check whether the keyboard wiring is bad or falling off.

Fault 6: manual / automatic crash

Troubleshooting:

1) Record the electronic gears in the system parameters; 2) Initialize the parameters by pressing the button G 3 of the right keyboard in turn under the main interface of the system; 3) Restart the system once more, fill the recorded electronic gears in the corresponding position, store the parameters and test the machine.

Fault 7: input / output no

Troubleshooting of hypertherm cnc plasma cutting machine:

1) check whether the input / output wiring is reliable.

2) check whether the 24V power is normal (the voltage between the 25 core interface 24 and the 25 legs) check the switching power supply.

3) whether the internal wiring of the system is loose.

Fault 8:USB cannot be transmitted

Troubleshooting:

1) U disk can not match with the system to replace other models or brands of U disk.

2) Check whether the U-disk indicator is on to check whether the internal wiring of the system is loose, check whether there is any foreign body in the USB socket, whether the pin is reconnected properly, and clean up the interface debris

Fault 9: after the processing program starts, automatically return to the main interface.

Troubleshooting:

1) test parameters after replacement of machining procedures.

2) initialize the parameters of the system.

Solution: inspection procedure

Fault 10: the system can only process straight lines, but not complete circles.

Troubleshooting of hypertherm cnc plasma cutting machine:

1) parameter problem initialization of system parameters.

2) procedure change procedure, trial run inspection procedure, or return to company inspection.
