- Conveyors: Master-follower synchronization with <10 ms latency.
4.3 HVAC Systems
- Free Cooling Integration: Seamless switching between mechanical and adiabatic cooling.
- Demand-Controlled Ventilation: Adjusts airflow based on CO2 sensors.
5. Installation and Commissioning Best Practices
5.1 Electrical Connections
- Power Wiring: Use 4-core cables with cross-sectional areas ≥4 mm² for L1/L2/L3/PE.
- Motor Cables: Limit length to 30 meters to minimize EMI; use ferrite cores for longer runs.
- Grounding: Connect PE directly to the drive’s terminal block and motor frame.
5.2 Parameter Tuning
- Motor Identification: Run the Auto-Adaptive Tuning routine to measure rotor resistance and leakage inductance.
- Application Macros: Select from preloaded settings (e.g., “Pump,” “Crane”) or customize via DriveConfig™ software.
- Energy Optimization: Enable “Sleep Mode” to de-energize the drive during idle periods.
5.3 Maintenance Schedule
- Daily: Check for error codes on the LCP.
- Monthly: Inspect cooling vents and fan operation; clean with compressed air.
- Annual: Verify torque performance using a dynamometer; update firmware.
