About ATV340U40N4 - ATV340, 4 kW Heavy Duty, 400 V, 3 phases, Ethernet

The

ATV340U40N4

is a 3-phase variable speed drive from the Schneider Electric Altivar Machine 340 series, designed for heavy-duty machine applications. It provides a rated power of 4 kW (5 HP) and features a slightly higher weight of 2.2 kg (4.9 lbs) compared to the lower-power models, while maintaining the same compact physical footprint.

Key Specifications

Power Rating: 4 kW (5 HP) for heavy-duty; up to 5.5 kW (7 HP) for normal-duty applications.
Voltage Range: 3-phase, 380V to 480V AC.
Current Rating:
- Heavy Duty: 9.3 A (continuous).
- Normal Duty: 12.7 A (continuous).
Dimensions: 85 mm (W) x 270 mm (H) x 232.5 mm (D).
- In Inches: 3.3 in (W) x 10.6 in (H) x 9.2 in (D).
Communication: Integrated Modbus serial line (RJ45) as standard.

Functional Highlights

This model shares the advanced machine-control features of the ATV340 range:

Superior Overload: Capable of handling 220% peak torque for 2 seconds (Heavy Duty), making it ideal for high-inertia starts in hoisting or material handling.
Safety Integrated: Embedded Safe Torque Off (STO), Safe Stop 1 (SS1), and Safely Limited Speed (SLS).
IoT Ready: Designed for seamless integration into the EcoStruxure Machine architecture using SoMove or EcoStruxure Machine Expert software.

The ATV340U40N4 shares the same core functional DNA as the smaller units in the series, but it is engineered to manage the higher electrical and thermal demands of a 4 kW (5 HP) motor.

Primary Functions

High-Torque Performance: Provides 220% nominal torque for 2 seconds. This is critical for 4 kW motors in applications like heavy conveyors or industrial mixers that require a powerful "kick" to start moving from a standstill.
Dynamic Motor Control: Manages 3-phase asynchronous and synchronous motors (including permanent magnet and reluctance motors) with high precision, supporting both open-loop and closed-loop (with an optional encoder card) configurations.
Safety Level: Integrated with Safe Torque Off (STO), achieving SIL3/PLe safety standards. This allows for safe machine intervention without cutting main power.
Regenerative Handling: Includes a built-in braking transistor. For a 4 kW load, this allows the drive to dissipate energy through an external resistor during rapid deceleration or "overhauling" loads (like a descending hoist).

Data & Connectivity

Modbus Integration: Uses the standard RJ45 port to communicate with PLCs for automated speed changes and status monitoring.
IoT & Maintenance: Compatible with EcoStruxure for remote diagnostics and predictive maintenance.
