Clogged chiller air filters or restricted airflow around the cooling unit. Low coolant level or incorrect water-to-glycol mix ratio.
integrated into the machine's control software or contact official support
Clean the guide rails and apply the recommended structural grease. Check if the axis is physically bound by scrap metal. Drive Amplifier Faults (Overcurrent)
Bystronic provides built-in documentation through the interface so you don't have to carry a paper manual: bystronic laser error code list
Check air conditioner connections and verify the selection list in the system settings. General Troubleshooting Steps
Bystronic systems categorize errors to help operators quickly isolate the issue. Most error notifications contain three vital pieces of information:
Gas mix deviations, high-voltage faults, or cooling irregularities (ByLaser or fiber power sources). Clogged chiller air filters or restricted airflow around
Navigating to the "Messages" or "Logging" tab (often under Modules) provides a history of MMC and CNC error logs. Initial Troubleshooting Steps
Errors in this category usually relate to the Bystronic cutting head (such as the ByCut or SSC head) and the capacitive sensing cycle that maintains nozzle distance from the metal sheet. Error: "Capacitive Height Sensing Fault" / Code 7102
The table fails to swap, often due to a guide pin issue. Troubleshooting: Check if the axis is physically bound by scrap metal
Replace the protective window using clean-room protocols immediately. Inspect the upper optics for damage. 3. Capacitive Height Sensing (Nozzle Distance) Errors
Navigate to the Service page -> Automation -> Manual Control .
Machine stops mid-cut on thick steel. Analysis: The error appeared only after cutting for 1 hour. Solution: The nozzle expanded due to heat from a piercing reflection. The fix involved switching to a heavier-duty copper nozzle and increasing the piercing time to allow heat dissipation.
: Overtemperature/Signal Cable . Possible broken cable between the ACC and the laser heat switches.
| Error Code | Message | Likely Cause | Immediate Action | | :--- | :--- | :--- | :--- | | 1210 | X-axis following error | Mechanical binding; servo tuning off; encoder feedback lost. | Manually push gantry (with motors off). Check for debris on rails. | | 1245 | Y-axis overcurrent | Brake not released; motor short circuit; cable damaged. | Power cycle machine. Inspect motor cables in cable carrier. | | 1302 | Z-axis reference point not found | Homing sensor dirty; collision damage to nozzle. | Clean limit switch. Manually lower / raise head (Jog mode). | | 1401 | Rotary axis (tube) timeout (ByTube) | Chuck jaws stuck; part slippage. | Reload tube; check jaw pressure. |
