Drive class and supply fit
The ATV930U30N4US is a variable speed drive from the Altivar Process ATV900 series, designed for asynchronous and synchronous motors. It accepts a 3-phase 380-480 V supply and delivers 7.2 A continuous output at 4 kHz carrier in normal duty, or 5.6 A in heavy duty. Motor power rating is 3.0 kW normal duty and 2.2 kW heavy duty — the heavy-duty figure governs applications with constant-torque loads like conveyors or extruders, while normal duty suits variable-torque pumps and fans.
Network topology and option slots
The drive ships with integrated Ethernet IP and Modbus TCP supporting half-duplex, full-duplex, and autonegotiation at 10/100 Mbits. For deterministic motion or existing fieldbus backbones, Slot A accepts Profibus DP V1, PROFINET, DeviceNet, EtherCAT, CANopen (daisy chain RJ45, SUB-D 9, or screw terminals), or Ethernet Powerlink modules. Additional I/O and encoder feedback modules populate Slot A, B, or C — including digital/analog I/O extension, output relay extension, and encoder interfaces for 5/12 V digital, analog, or resolver types. This lets the drive serve as a motion controller without a separate PLC for simple positioning axes.
Enclosure, cooling, and environment
IP21 protection and UL type 1 enclosure suit indoor panel mounting in clean environments — not washdown. The wall-mount design requires vertical orientation within ±10 degrees and draws 38 m³/h (10038.7 Gal/hr US) of cooling air. Ambient humidity range is 5-95% non-condensing per IEC 60068-2-3. Vibration resistance is 1.5 mm peak-to-peak at 2-13 Hz and 1 gn at 13-200 Hz per IEC 60068-2-6; shock resistance is 15 gn for 11 ms per IEC 60068-2-27. Altitude derating applies above 1000 m — 1% current reduction per 100 m up to 4800 m.
Regulatory and compliance scope
The drive carries CE marking and complies with UL 508C, IEC 61800-3 (EMC), IEC 61800-5-1 (safety), IEC 61000-3-12 (harmonic), IEC 60721-3 (environmental), IEC 61508 (functional safety), and IEC 13849-1. It is TAA/BAA/BABA compliant via COTS — relevant for US federal procurement. Integrated EMC filter meets conducted emission limits for most industrial installations; an optional EMC plate is available for higher-performance filtering. The braking chopper is included as standard — external resistor sized for the deceleration duty cycle prevents DC-bus overvoltage on fast stops.
Sourcing and lifecycle position
No official successor or pin-compatible alternative exists within the Altivar Process family at this power rating. The drive uses screw terminals for line (2.5-6 mm² / AWG 14-10), motor (2.5-6 mm²), DC bus (2.5-6 mm²), and control (0.5-1.5 mm² / AWG 20-16) connections.
