Bystronic Laser Error Code List -

These errors are common in both Fiber and CO2 machines, specifically regarding the cutting head (ByAutonom, Precitec, or Raytools).

| Code / ID | Description | Probable Cause & Solution | | :--- | :--- | :--- | | H200 | Focus Position Error | The Z-axis cannot find the focal point. The focusing lens may be loose, or the capacitance sensing is failing. Clean the lens and check the Z-axis drive. | | H210 | No Signal from Head | Communication lost between the cutting head sensor and the CNC. Check the fiber optic cable (for sensor data) or the serial connection. | | H300 | Crash / Collision | The cutting head hit the material or the slats. Check for tip damage. Recalibrate the head. | | H405 | Capacitive Sensor Drift | The height control system is drifting. Perform a "Sensor Calibration" or "Zero Set" on the head. | | Lens Temp High | Overheating Optics | Cooling water flow to the cutting head is restricted, or the lens is

Many errors are displayed on the ByVision interface and can often be resolved with basic maintenance or a system reset. E7: Shutter Locked in Open Position

Cause: The shutter mechanism is failing to close between cuts.

Fix: Check for dirty pneumatic cylinders or sensor failure. Cleaning the cylinders often restores motion. W-Axis Warning / Frequency Error

Cause: The measured frequency is outside the expected range for the height sensing system.

Fix: Thoroughly clean the cutting head, including ceramics and nozzle holders, with alcohol. Check for moisture in the D-sub connector or a short in the nozzle assembly. 700248: Loading Unit Not in Safety Position

Cause: The automation unit is not in a safe range for operation.

Fix: Manually move the loading unit back into the safe position using the control buttons and press the RESET key. I32.5 = 0: Electric Panel Air Conditioner Error

Cause: Fault in the cooling system for the electrical cabinet. bystronic laser error code list

Fix: Check air conditioner connections and verify the selection list in the system settings. General Troubleshooting Steps

If you encounter an unlisted code, follow these standard diagnostic steps: Report a fault - Bystronic

When a Bystronic laser throws an error, it can bring production to a grinding halt. While the exact codes can vary depending on your specific machine (Bystar, BySmart, BySprint, etc.), most common issues fall into categories like power supply, laser head alignment, or gas pressure. Common Bystronic Laser Error Codes

Many Bystronic systems share a similar numerical coding logic for their resonator and cutting head systems. Error Code Issue Description Potential Cause & Troubleshooting 202 / 234 Power Supply Fault

Often indicates a failure in the high-voltage power supply or a tripped breaker. Check external power stability. 224 Handpiece/Cutting Head Issue

Could be a communication error with the head. Inspect the connection cables. 246 / 249 Laser Head / Flashlamp Failure

The flashlamp is failing to start. This is common in older YAG-based systems. 323 Water Flow Issue

Cooling system problem. Check your chiller for low water levels or clogged filters. 345 Broken Flashlamp

The lamp has reached its end of life or physically cracked. Replacement is usually required. 367 Power Supply Failure A critical failure in the internal power supply unit. ByPOS Error Adaptive Mirror Issue These errors are common in both Fiber and

Often caused by a dirty inline filter or a box issue. Clean the filter inside the head carriage. Z Plausibility Head Height Error

Likely caused by dirty or damaged ceramics in the cutting head. Essential Troubleshooting Steps

If you see an error not listed above, try these universal "first-response" steps:

Check the "Help" Button: Most Bystronic ByVision interfaces have a "Help" or "?" icon next to the error code that provides a specific description and suggested remedy.

Inspect the Consumables: Many "cutting quality" errors or head alarms are simply due to a worn nozzle, dirty lens, or damaged ceramic.

Monitor Gas & Pressure: Ensure your N2 or O2 levels are correct and that the gas turbine is functioning normally.

Reset & Reboot: For software-related glitches, a full system restart can often clear "ghost" errors that occurred during a power flicker. When to Call Service

If you encounter a "Resonator Error" or any code involving "High Voltage," it is best to contact Bystronic Service directly. Attempting to repair internal resonator components without proper training can be dangerous and may void your warranty.
