Operational Guidelines for SYNTEC CNC Control Systems: Critical Precautions And Best Practices

1. Secondary Development and System Integration

• Risk: Open architecture may cause conflicts in custom code or reduce system stability.

• Actions:

  • ✅ Perform rigorous testing on offline simulation platforms (e.g., SYNTEC SDK Emulator) before deploying new modules to production equipment.

  • ✅ Implement version control (e.g., Git) for PLC programs, macros, and third-party DLLs to ensure traceability.

  • ⚠️ Restrict access: Only authorized engineers may modify system-level parameters (e.g., $PLC_PARAM).

2. Servo System Compatibility Tuning

• Risk: Third-party servo motors may induce vibration/overshoot.

• Procedure:

  plaintext

  1. Initialization: Load motor manufacturer's `.srv` file via [SYNTEC Tuning Studio].  
  2. Rigidity adjustment: Execute "FFT analysis", incrementally raise [velocity loop gain] to critical value, then reduce by 15%.  
  3. Anti-vibration: Activate "Notch Filter" with center frequency = tremor frequency × 0.8 if cutting chatter occurs.  

  • 📌 Key parameters: P2-10 (velocity loop gain), P2-15 (notch frequency).

3. System Upgrades and Backup Management

• Critical steps:

  • 🔄 Pre-upgrade backup: Save NC parameters + PLC programs + user macros to external storage (all three are mandatory).

  • ⚠️ Version verification: Confirm firmware-hardware compatibility (e.g., 21TA systems cannot run 22MA firmware).

  • 📅 Scheduled maintenance: Check CF card health bimonthly using chkdsk /f.

4. Thermal Management and Environmental Adaptation

• Hardware safeguards:

  • 🌡️ Temperature control: Maintain cabinet temperature ≤40°C (install industrial AC/fans); clean CPU heatsinks periodically.

  • 🛡️ Noise immunity:

    • Separate power/signal cables by ≥15cm;

    • Use twisted-pair shielded cables for analog I/O (ground resistance <4Ω).

5. Localization for Chinese Market

• Optimizations:

  • 🇨🇳 Chinese interface: Verify Language=Chinese_GB2312 in System.ini if garbled text appears.

  • 🛠️ Domestic device integration:

    • Tool setters: Map #1000~#1003 to tool compensation signals in PLC;

    • MES communication: Enable IP whitelist when using Modbus TCP to block unauthorized access.

6. Rapid Fault Response

• Diagnostic tools:

  • 🔧 Real-time monitoring: Check PLC status tables via SYNTEC Diagnostics (focus on abnormal X/Y/M points).

  • 🚨 Alarm resolution:

    • E949 (communication timeout) → Inspect Ethernet switch ports;

    • E1120 (servo overload) → Verify mechanical transmission resistance.
