Troubleshooting Steps for “IPG Laser: Over Temperature” Error

Troubleshooting Steps for “IPG Laser: Over Temperature” Error

1. Check continuous operation time:
   Confirm with the operator whether the laser has been running continuously for a long period, which may trigger overheat protection.
   Solution: Power off the machine, wait for a short period, then power it back on.

2. Inspect the signal cable:
   Check whether the signal cable connecting the control board to the laser is loose.
   Solution: Re-seat the cable or replace it with a new one if necessary.

3. Verify the laser power supply:
   Ensure that the laser power supply voltages (V+ and V-) are normal (typically 24V or 48V) and that the laser indicator light is on.

4. Consider the control board or the laser module:
   If the above steps do not resolve the issue, inspect the control board and the laser module for potential faults.

5. Check software settings:
   Verify whether the relevant parameter in the software is selected.
   Solution: If it is checked, uncheck the parameter.
