Schneider Electric ATV320U22N4B Variable Frequency Drive

Schneider Electric ATV320U22N4B is a 2.2 kW Altivar Machine ATV320 variable-frequency drive designed for 380 to 500 V three‑phase motors in a compact book‑format, cabinet‑mount enclosure. This 3‑phase drive delivers a nominal output current of 5.5 A and supports open‑loop motor control, making it well suited for small to mid‑size automation tasks such as conveyors and automated lines where precise speed control is required without feedback. The unit is IP20 rated and includes a built‑in Class C2 EMC filter to meet common industrial noise requirements in cabinet installations. Safety is built in with STO (Safe Torque Off) and seven discrete inputs (DI1–DI7), with DI5 programmable as a high‑speed pulse input up to 0–30 kHz, enabling flexible integration with sensors and control logic. Native communication includes Modbus serial and CANopen, with option cards available for Profinet, EtherNet/IP, EtherCAT, Profibus DP, and other fieldbuses to integrate seamlessly with Schneider Electric and third‑party controllers. As part of the Altivar Machine ATV320 family, the U22N4B variant is designed for cabinet mounting and delivers reliable motor control in a compact footprint, suitable for a range of industrial applications where space, performance, and robust electrical compatibility matter.
