: General Beam Source Error . Indicates a serious fault in the RF circuit or internal switch, often triggered by overtemperature (>60 °C).
Comprehensive Bystronic Laser Error Code List and Troubleshooting Guide (2026)
| Error Message | Explanation | Common Causes & Troubleshooting Steps | |:---|:---|:---| | | A problem with the capacitive sensor in the cutting head. The feedback signal for the distance between the nozzle and the sheet metal is not what the system expects. | • Dirty Cutting Head : This is the most frequent cause. Cleaning the head, including the capacitive sensor board, often resolves the issue. • Faulty Sensor Board : If cleaning doesn't help, the sensor board may need replacement. • This warning may not stop the machine from cutting immediately but should be addressed to prevent future issues. | | Error n2 | An error related to one of the machine's axes, often the Y-axis, hitting its end-of-travel limit. | • Machine Limits : The machine may have been sent beyond its travel range. Check your part's position in the program relative to the machine bed. • Axis Position : Adjust the start position of the Y-axis in your program or on the machine's control panel. | | Amp Fault Z2 | A problem with the drive system for the Z2 bearing channel. | • Mechanical Issue : A bearing in the Z2 axis could be damaged or seized. • Drive Issue : The servo driver (amplifier) for the Z2 axis might be faulty. • This error will stop the machine completely until resolved. |
: For mechanical jams like table interchange failures, operators may need to use the "Service Machine" window in the control software to operate drives independently for manual realignment. Regular Maintenance bystronic laser error code list
Bystronic continuously updates firmware. If you see a code not in this list (e.g., E-7889 specific to a ByStar 4020):
Dirty nozzle, loose ceramic part, or a damaged sensor cable.
Triggered when the cutting head moves beyond its physical or software-defined boundaries. : General Beam Source Error
Often caused by empty tanks or incorrect mixing ratios in CO2 lasers.
After a weekend shutdown, the machine lost its X/Y reference. Solution: The absolute encoder battery (mounted on the Siemens drive) was old. Replacing the battery with the machine powered ON (critical step!) resolved the issue.
The machine throws a hard fault when attempting to fire the laser. The feedback signal for the distance between the
The system shuts down within minutes of turning on the resonator.
