Bystronic Laser — Error Code List
| Error Message | Likely Cause | Troubleshooting Steps | | :--- | :--- | :--- | | | Communication failure between the PC and the CNC controller. | 1. Check the physical interface connections (often TOSLINK fiber optic cables). 2. After power outages, the CNC memory may be corrupted and require restoration. | | "Line 3: parse error" (G-code) | G-code or post-processor incompatible with Bystronic requirements. | 1. Ensure the first line of code contains the required "%" symbol. 2. Use a Bystronic-approved post-processor for your CAM software. | | "Laser fault" / "Laser interlock" / "Resonator error" | General laser control board (E08675A) or interlock circuit issue. | 1. Check all safety interlocks (doors, E-stops). 2. A faulty controller board (E08675A) can cause this; symptoms include unstable output power and inability to fire the laser. |
: Immediate shutdowns triggered by safety interlocks or critical hardware failures. Common Categories and Challenges
The following table compiles error messages, codes, and issues reported by users in public forums and guides. Use this as a starting point for diagnosis. bystronic laser error code list
Write down the exact error number and any accompanying text string. Note what the machine was doing (e.g., piercing, rapid moving, changing pallets) when the fault occurred.
Mechanical obstruction on the rack-and-pinion or linear guide rails. Lack of lubrication causing excessive friction. | Error Message | Likely Cause | Troubleshooting
Light curtains at the shuttle table or loading automation are interrupted.
Cycle the gas purge manually. If the error persists, the electronic proportional valve may require service or replacement. Motion Control & Drive Error Codes If the error persists
| Code | Description | |------|-------------| | E-5001 | Gas type not recognized | Wrong gas connected, pressure sensor fault | | E-5005 | Low nitrogen pressure | Supply line, regulator, valve stuck | | E-5010 | Low oxygen pressure | Same as above | | E-5020 | High pressure air missing | Compressor, dryer, filter clogged |
While this list covers many specific codes, a systematic approach is essential when an alarm appears.
