Parameters Electrical & Power Product Type: Variable Frequency Drive (VFD) – Altivar 71 series Model: ATV71HC16N4 Rated Motor Power: 160 kW (approx. 250 hp) for 3‑phase motors at 380…480 VAC systems Input Voltage: 380…480 VAC ±15 % (3‑phase), 50/60 Hz Nominal Output Current: 314 A at 2.5 kHz switching frequency (both 380 V and 460 V systems) Line Current: ~289 A at 380 VAC / ~233 A at 480 VAC Output Frequency Range: 0.1 … 500 Hz (adjustable) Switching Frequency: 2.5 kHz nominal, adjustable up to ~8 kHz with derating Power Control Profile: Voltage/frequency and sensorless flux vector control (SFVC); optional closed‑loop vector control with encoder Overload Capability: Transient currents up to ~518 A (2 s) and ~471 A (60 s) above rated in some operating conditions Features Integrated EMC Filter: Helps reduce electrical noise emissions in industrial networks. Built‑in Heatsink: For effective thermal dissipation in heavy‑duty use. Control Modes: V/f (voltage/frequency) control Sensorless flux vector control (SFVC) using drive estimators Full vector control with sensor (when encoder feedback is fitted) Energy Adaptation (ENA): For operation with unbalanced loads. Modbus/CANopen: Communication support depending on option modules and configuration.
