Bystronic Laser Error Code List

| Code | Subcode | Error Name | Description & Solution | | :--- | :--- | :--- | :--- | | | E760.0 | Encoder over-temperature | Encoder is overheating. Check for adequate cooling and inspect the motor/axis for excessive friction. | | E994 | E994.0 | Station numbers conflict | Duplicate or conflicting station numbers in the automation system. Review and correct station configurations. | | EB00 | EB00.1 | Position deviation overflow | The actual axis position deviated too far from the commanded position. Check for mechanical binding, loose couplings, or servo tuning issues. | | EB01 | EB01.0 / .1 / .2 / .3 | Position reference increment errors | The position reference increment is too large, continuous, or has overflowed. Often tied to incorrect electronic gearing or CAM profile settings. | | EB02 | EB02.0 / .1 | Fully closed-loop position deviation error | Excessive deviation in a fully closed-loop control system. Inspect feedback devices (linear scales) and mechanical drive components. | | EB03 | EB03.0 / .1 / .2 | Electronic gear ratio beyond limit | The programmed electronic gear ratio exceeds the allowable limit for H05.02 or the electronic gear settings 1 and 2. Recalculate and correct the ratio. | | EB04 | EB04.0 / .1 | Gantry position deviation | Errors related to gantry axis misalignment. Indicates the two sides of the gantry are not synchronized. Re-home and check for mechanical obstructions. | | EE09 | EE09.0 / .1 | Software position limit / Home setting error | The programmed software limit or home position setting is invalid. Review and correct these parameters in the CNC software. |

| Error Code | Message | Fix | | :--- | :--- | :--- | | 9100 | Communication timeout CNC-HMI | Reboot industrial PC. Check Ethernet cable between control cabinet and operator panel. | | 9205 | Cutting plan inconsistent | Post-processor version mismatch. Regenerate NC code from BySoft 7. | | 9210 | USB drive not recognized | Format drive to FAT32; ensure it’s <32GB. |

While many codes are user-serviceable, certain errors—specifically those involving , turbine failures , or high-voltage boards —require a certified Bystronic technician. Attempting to fix these yourself can void warranties or lead to expensive secondary damage. | Code | Subcode | Error Name |

: Regular cleaning of laser optics (lenses and mirrors) and checking the cooling system (water levels and flow) can prevent up to 30% of standard technical errors. near you or see maintenance kits for these laser models? Report a fault - Bystronic

Restart the system sequentially (Chiller -> Resonator -> CNC). Step 4: Inspect Consumables and Mechanics If the error relates to the cutting head or axis movement: Check the cutting nozzle for damage or debris. Clean the height sensor calibration ring. Review and correct station configurations

The chiller is powered on and showing normal operating temperatures.

Instead, the only sound was the hum of the cooling unit and the frantic typing of Elias, the senior maintenance technician.

Gently clean the linear scales following Bystronic maintenance manual specifications (typically using anhydrous alcohol and lint-free cloths).
