ATV320U55N4C Selection Notes
Do not select this VFD merely based on motor power. Check the points below to avoid wrong selection.
1.Verify motor rated current
5.5 kW is for reference only. Follow the rated current on the motor nameplate and ensure it falls within the VFD output range.
2.Confirm load conditions
The ATV320U55N4C is a 5.5 kW heavy‑duty unit. Check actual startup and shock‑load conditions to confirm compatibility.
3.Check power supply
Only for 3‑phase 380‑500 V AC, not compatible with single‑phase 220V.
4.Confirm communication requirements
Modbus and CANopen are built‑in for basic control. Additional communication expansion cards are required for PROFINET, EtherCAT or EtherNet/IP.
5.Pay attention to installation environment
IP20 protection rating. It must be installed inside control cabinets with proper ventilation and heat dissipation.
