Bystronic Laser Error Code List Direct

| Error Code | Message | Immediate Fix | | :--- | :--- | :--- | | 7005 | Chiller flow rate too low | Check pump impeller; clean Y-strainer; look for kinked hoses. | | 7020 | Chiller water conductivity high (Fiber) | Deionized cartridges exhausted. Replace DI resin and test conductivity (<0.1 µS/cm). |

These errors usually relate to the CNC control (BySoft/ByCNC) or general machine operation. bystronic laser error code list

| Code / ID | Description | Probable Cause & Solution | | :--- | :--- | :--- | | 100x | Emergency Stop Activated | The E-Stop button was pressed or a safety circuit was broken. Check all E-Stop buttons (control panel, mobile unit, rear cabinet). Reset the button and clear the error. | | 200x | Drive Error / Axis Fault | Servo drive fault. Often caused by overload, collision, or power supply issues. Check for mechanical obstructions on the X, Y, or Z axes. Reset the drives. | | 300x | Lubrication Error | The lubrication system is empty or blocked. Refill the oil reservoir. Check for clogged lines or failed pump. | | 400x | Pneumatic Pressure Low | Cutting gas (N2, O2) or assist gas pressure is below the minimum threshold. Check the main supply, open the main valve, or check for leaks in the lines. | | 501 | Door Interlock Open | The safety door or cover is open while the machine is trying to operate. Close doors securely. | | 605 | Reference Point Not Reached | The machine cannot find its home position. Check limit switches and axis sensors. Re-reference the machine. | | 700x | Cooling System Fault | The chiller is not running or the temperature is out of range. Ensure the chiller is powered on and water levels are sufficient. Clean chiller filters. | Deeper diagnostics:

Symptom: 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. | Error Code | Message | Immediate Fix
