The ATV930D22N4US is a 380...480 V 3-phase variable speed drive from the Altivar Process ATV900 series, rated for 22.0 kW normal duty and 18.5 kW heavy duty. It delivers 46.3 A continuous output at 4 kHz in normal duty, and 39.2 A at 4 kHz in heavy duty. The drive includes an integrated braking chopper for handling regenerative loads, and its IP21 enclosure with UL type 1 rating suits it for clean indoor panel or standalone installation.
The 46.3 A nominal output current at 380-480 V defines the drive's thermal capacity for continuous motor operation. The heavy-duty rating of 39.2 A is the limit for constant-torque loads like conveyors or extruders; the normal-duty 46.3 A covers variable-torque loads such as pumps and fans where overload margin is lower. The 22.0 kW / 18.5 kW motor power figures are the typical induction motor sizes the drive is designed to control — match these to your motor nameplate for a direct fit. The supply voltage range covers common 400 V and 480 V industrial grids; the drive can accept 380 V through 480 V without reconfiguration.
Integration notes
The drive mounts vertically on a wall. Control wiring uses screw terminals accepting 0.5...1.5 mm² (AWG 20...16); power terminals accept 10...16 mm² (AWG 8...6) for line, motor, and DC bus connections. The integrated EMC filter covers conducted emissions for most installations; an optional EMC plate is available for stricter environments. Slot A accepts communication modules for Profibus DP V1, PROFINET, DeviceNet, EtherCAT, CANopen (RJ45 or SUB-D 9 or screw terminals), or Ethernet Powerlink. Slots A/B/C also accept digital/analog I/O extension or output relay modules. The drive supports Ethernet IP/Modbus TCP with half/full duplex and auto-negotiation at 10/100 Mbit/s, plus serial at 4.8, 9.6, or 19.2 kbps. The onboard PID regulator handles closed-loop process control without an external controller.
