Product details

The ATV350U22N4FS is a 2.2 kW Altivar Machine drive rated 8.5 A output at 460 V, 3-phase input. It handles both asynchronous and synchronous motors across a 1-599 Hz output frequency range. Switching frequency is adjustable from 2 to 16 kHz, with current derating of 0.5 % per 100 m above 1000 m altitude. Built-in STO (safe torque off) meets SIL 3 / PL e per IEC 61800-5-2 and IEC 61508, so you can skip an external safety relay for the drive axis. The integrated Class C2 EMC filter covers conducted emissions for first-environment (residential) installations up to 10 m cable runs. Communication options include EtherNet/IP, EtherCAT, Modbus TCP, and PROFINET via M12 connectors on the base. The internal 24 V DC supply powers the logic inputs directly, no separate PSU needed for the control side.

Wall-mounted unit, dimensions 12.2 x 20.6 x 9.2 in (H x W x D). Natural air cooling (AN) — no fan to fail, but keep the gland plate clear for convection. Pollution degree 2 environment, horizontal operating position. Line supply phase-loss, motor phase-loss, overvoltage, undervoltage, overheating, and short-circuit protections are all onboard. Motor overload protection with PTC probes is supported.

Frequently asked questions

What safety functions does the ATV350U22N4FS include?

It includes STO (safe torque off) as standard, compliant with IEC 61800-5-2 and IEC 61508 for SIL 3 / PL e applications.
