The deionized water loop cooling the laser source or cutting optics has breached maximum or minimum temperature thresholds. Common Causes:
Check the cabinet for humidity. Inspect the glass tubes for any signs of physical damage or discoloration. 3. Chiller & Cooling System Errors
Maintaining peak productivity with Bystronic laser cutting systems requires a proactive approach to troubleshooting. When your machine pauses and a numerical code flashes on the screen, it isn't just an interruption—it’s the machine telling you exactly what it needs.
Specifically refers to low oil levels in the X1, X2, or Y axes. Checking the lubrication switch and refilling the reservoir usually clears these. 3. Cooling and Environmental Alarms bystronic laser error code list
| Code / ID | Description | Probable Cause & Solution | | :--- | :--- | :--- | | | Laser Source Temperature | Internal temperature of the laser source is too high. Check the internal chiller, clean air filters on the power unit, and ensure ambient temperature is not excessive. | | E1002 | Laser Diode Current | Current limit reached or diode failure. This usually requires a service technician to replace the diode stack or adjust parameters. | | E1005 | No External Enable | The "Laser On" signal is missing. Check the interface cable between the CNC and the Laser Source. | | E2001 | Beam Delivery Fault | Safety shutter did not open or close in time. Check the pneumatic actuator for the safety shutter. | | E3005 | Fiber Cable Connection | The fiber optic cable is not connected properly or the connector is dirty. Warning: Clean connectors strictly according to the manual using proper splices and alcohol. Dirty connections destroy fiber tips. | | W4001 | Power Limit Warning | The requested power exceeds the current capability of the laser source (often happens at very low duty cycles or high modulation). |
: Open the diagnostics menu to see what minor errors triggered just before the main shutdown.
| Error Message | Explanation | Common Causes & Troubleshooting Steps | |:---|:---|:---| | | The CNC control software has stopped processing the program at a specific line number ( N2/1003 ) and cannot continue. | • Axis Limits : The machine may be trying to move an axis beyond its physical limits. Check the starting position and program coordinates. • G-Code Issue : There might be a syntax error or an unsupported command in your program at that block number. Review your generated code. | The deionized water loop cooling the laser source
Verify gas regulator settings and check for leaks in the supply lines. Dirty lens or damaged ceramic part.
Do immediately hit reset. Read the full message on the ByVision screen. Often, the subtext suggests a cause (e.g., “Check nozzle clearance”).
When you encounter an unknown code not listed in any you have, follow this SOP: Specifically refers to low oil levels in the
Bypass the surface-level alarm and look at the "Error History" log in the Bystronic software. This often shows a chain of events leading up to the stoppage.
Often a sign of mechanical resistance, such as a lack of lubrication on the rails or a physical obstruction on the slats. 3. Cutting Head and Sensor Errors (The "ByPos" System)
