6. Selection Recommendations
- Power Requirements: Match voltage (200–230V) and phase (3-phase) with the system.
- Load Profile: Choose based on peak torque needs (e.g., 150% overload for short-duration tasks).
- Environment: Ensure IP20 protection is suitable for the operating environment (non-hazardous, dry locations).
- Compatibility: Verify RS-485 compatibility with existing control systems.
7. Precautions
- Installation:
- Mount vertically in a well-ventilated area (avoid direct sunlight and temperatures >50°C).
- Use shielded cables for encoder and communication wiring to prevent EMI.
- Operation:
- Allow 30 minutes for warm-up before high-precision tasks.
- Avoid frequent overloads to extend lifespan.
- Maintenance:
- Clean dust regularly (use compressed air).
- Replace capacitors every 5–7 years (depending on usage).
