Schneider Electric ATV310HU30N4 – 3kW 400V Three-Phase Variable Speed Drive | Altivar 310 Series
Engineering Background
The Altivar 310 series represents Schneider Electric’s purpose-built solution for simple machine applications demanding reliable, energy-efficient motor control. Designed for OEM integration and panel-building environments, the ATV310 platform delivers consistent performance across pumping, fan, conveyor, and compressor applications without the complexity overhead of full-featured drives.
Product Positioning
The ATV310HU30N4 targets procurement engineers sourcing a compact, DIN-rail-compatible 3kW drive for 380–460V three-phase networks. Its plug-and-play commissioning, integrated EMC filter, and IP20 enclosure make it the default choice for control cabinet integration where space, compliance, and commissioning time are primary constraints.

System Architecture & Signal Flow
The ATV310HU30N4 operates on a standard AC-DC-AC conversion topology. Three-phase 400V input is rectified to a DC bus (~565V), then pulse-width modulated (PWM) at 4–16 kHz to synthesize variable-frequency AC output. The integrated flux vector algorithm continuously estimates rotor flux position from stator current feedback, enabling torque control without a physical encoder.
Typical wiring architecture: PLC analog output (0–10V) → AI1 setpoint → ATV310 speed reference → PWM output → 3-phase induction motor. Fault relay (R1A/R1B/R1C) wired to PLC DI for supervisory monitoring. Modbus RTU over RS-485 (RJ45) for parameter read/write and status polling.

Technical FAQ
Q: Is the ATV310HU30N4 compatible with single-phase 220V input?
A: No. This model requires three-phase 380–460V supply. For single-phase applications, refer to the ATV310H series with suffix N4E or HU variants rated for 1-phase input.
Q: Can I use an external EMC filter?
A: The integrated Class C2 filter is sufficient for most industrial environments. For Class C1 (residential proximity) requirements, an additional external filter may be added.
Q: What motor types are compatible?
A: Standard three-phase asynchronous (induction) motors. Permanent magnet synchronous motors (PMSM) are not supported on the ATV310 platform.
Q: Is a braking resistor included?
A: No. The internal braking transistor is included; an external resistor must be sized and sourced separately based on load inertia and deceleration requirements.
Q: What is the warranty?
A: Konmask.com provides a 12-month warranty against manufacturing defects from date of dispatch.
