| Error Code | Description | Likely Cause | Immediate Fix | | :--- | :--- | :--- | :--- | | | Connection to NC lost | Ethernet cable unplugged or firewall active | Reboot the Industrial PC. Disable Windows updates. | | W-6020 | USB dongle (License) missing | Dongle vibrated loose | Plug into rear USB port. Use USB extension to secure. | | E-6050 | Hard disk full | 10+ years of error logs | Archive Logs to USB. Delete C:\Bystro\Logs\*.txt . | | I-6100 | Program incompatible | NC code from old CAD/CAM version | Repost the part using current Bystronic Post Processor. |

For limit alarms (like Z-axis), try disconnecting the power for 5–10 minutes to allow the system to clear its memory before homing to "0".

Laser cutting generates massive amounts of heat. The chiller must maintain a strict temperature range to prevent component damage. Low Flow Rate

: Voltage Module/Power Supply Error . The voltage is too high or too low. Requires checking contacts in the laser head or cooling system.

The machine cannot reach the programmed gas pressure listed in the cutting plan. Common Causes: Internal gas valve stuck due to particulate contamination. bystronic laser error code list

Insufficient external ventilation, dirty condenser coils, or low refrigerant.

The machine stops during a sharp turn or high-speed move.

| Error Code | Description | Likely Cause | Immediate Fix | | :--- | :--- | :--- | :--- | | | Resonator pressure too low | Gas bottle empty or regulator failure | Check He/N2/CO2 bottles. Switch to backup bank. | | E-1024 | Turbo blower speed fault | Turbo bearing wear or VFD malfunction | Do not restart. Call service. Requires turbo rebuild. | | E-1040 | Resonator temperature > 40°C | Chiller failure or blocked air filters | Clean chiller condenser. Check coolant level. | | W-1105 | Output power deviation > 10% | Dirty output coupler or aging flashlamps (Fiber: diode degradation) | Clean optics. Schedule lamp replacement (CO2). | | E-1150 | RF drive fault (Fiber) | Loose ribbon cable or failed pre-amplifier | Reseat connectors. Reboot the laser rack. |

Laser machinery utilizes high voltages, invisible radiation, and high-pressure gases. Always follow your facility's lockout/tagout (LOTO) protocols. If an error code points to internal resonator issues or complex electrical faults, contact an authorized Bystronic service technician.

: Mirror Not Closed . Specific errors for Z, Y, or X-axis mirrors indicating the protective covers or the mirrors themselves are not in the correct position.

Laser shuts down immediately; warning regarding protective glass temperature or contamination. Common Causes:
