Caused by measured frequency falling outside the controller's set range. This is frequently due to dirt or moisture in the nozzle holder or the D-sub connector Servo Alarm:
While specific codes vary by model (e.g., BySprint, Bystar), common high-level issues include: 700511 - N2 Input Pressure Insufficient : Nitrogen gas pressure is below required levels. 700834 - Nozzle Distance Control : The nozzle has contacted the sheet metal. 700739 - Dust Filter General Error : Check the dust filter unit for blockages or malfunctions. 700637 - Light Path Safety Deactive
Nitrogen or Oxygen pressures do not match the cutting parameter requirements. bystronic laser error code list
The deionized water loop cooling the laser source or cutting optics has breached maximum or minimum temperature thresholds. Common Causes:
Manually reset the focus axis through the service menu options. 3. Laser Source & Chiller Anomalies (5000–6000 Series) 700739 - Dust Filter General Error : Check
Check the cooling fans on the electrical cabinet doors. Check the status LEDs directly on the drive modules inside the cabinet to read the sub-fault codes. Preventive Practices to Minimize Error Codes
"Can we bypass the check?" Miller asked. Common Causes: Manually reset the focus axis through
Inspect water filters; ensure all coolant valves are fully open. Coolant Temperature High Ambient temperature too high or dirty condenser.
