Bystronic Laser Error Code List May 2026
Before diving into specific codes, it’s important to understand Bystronic’s error logic. Errors are rarely random. They follow systematic families:
By understanding this structure, you can prioritize your response. A 6xxx error might mean a door sensor is dirty; a 4xxx error could mean your helium tank is empty. bystronic laser error code list
| Code Range | Category | Description | | :--- | :--- | :--- | | 1xxx – 1xxx | Laser Source | Resonator, gas mixture, or beam path issues. | | 2xxx – 3xxx | Axis & Drive | X/Y/Z axis positioning, motors, or encoders. | | 4xxx – 5xxx | Cutting Head & Optics | Focus position, lens contamination, or nozzle collision. | | 6xxx – 7xxx | Gas & Assist Gas | Pressure too low/high, gas type mismatch, or leaks. | | 8xxx – 9xxx | Cooling System | Water flow, temperature, or chiller faults. | | 10xxx – 12xxx | Control & Software | Communication errors, software crashes, or ByVision issues. | Before diving into specific codes, it’s important to
Symptom: 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. By understanding this structure, you can prioritize your
| Error Code | Message / Meaning | Common Cause & Fix | | :--- | :--- | :--- | | E-1120 | Resonator pressure too low | Refill laser gas mixture or check pressure sensor. | | E-1215 | Laser pulse not fired | Check firing signal, high-voltage supply, or PSU. | | E-2103 | X-axis following error | Mechanical binding, bad encoder, or servo drive fault. | | E-2208 | Z-axis soft limit reached | Incorrect zero point; recalibrate cutting head. | | E-3125 | Collision detected on cutting head | Nozzle hit workpiece or sheet; re-teach head position. | | E-4022 | Capacitive sensor out of range | Dirty nozzle tip, damaged sensor cable, or wrong standoff. | | E-4510 | Lens temperature too high | Cooling water flow low; clean chiller filter or refill coolant. | | E-5120 | Assist gas pressure too low | Check tank level, regulator, or solenoid valve. | | E-6102 | Cooling water flow interrupted | Pump failure, air in system, or blocked hose. | | E-7801 | ByVision communication timeout | Restart HMI; check Ethernet cable or IPC. |
