        Overview Manuals Specifications Application Firmware & Updates Configuration

        Features:

        • Delivers 4kW (5HP) in a compact 3.1kg package with 170-200% overtorque and 150% braking torque, ideal for simple machines requiring frequent starts and stops.
        • Provides high torque performance at low speeds for asynchronous motors without requiring an encoder, simplifying installation while maintaining precise speed control.
        • Features built-in Modbus and CANopen protocols, 3 analog inputs (configurable voltage/current), 6 discrete inputs, 1 analog output, and 2 relay outputs. Supports optional Profibus DP, DeviceNet, and Ethernet communication cards.
        The ATV312HU40N4 is engineered for simple machine applications where space is limited but performance cannot be compromised. Despite its compact dimensions of just 184mm × 142mm × 152mm and weight of 3.1kg, this drive delivers 4kW (5HP) of motor power. The transient overtorque capability of 170-200% of nominal torque allows the ATV312HU40N4 to handle demanding start-up conditions, such as conveyors starting under load or mixers with high-inertia loads. The braking torque reaches 150% for 60 seconds when used with an external braking resistor, enabling rapid deceleration for applications like positioning or emergency stopping.

        The ATV312HU40N4 utilizes sensorless flux vector control technology to deliver exceptional motor performance without the cost and complexity of an encoder feedback device. This control method continuously calculates the motor's rotor position and speed using electrical measurements rather than physical sensors. The result is high starting torque—typically 170% of nominal torque—even at very low speeds, enabling applications such as hoists and elevators to lift full loads from standstill. The ATV312HU40N4's sensorless flux vector control also provides stable speed regulation under varying loads, maintaining setpoint speed even when the mechanical load changes.

        The ATV312HU40N4 simplifies machine integration with its comprehensive I/O and built-in communication capabilities. Three analog inputs provide flexibility: AI1 accepts 0-10V voltage signals, AI2 accepts ±10V bipolar signals for bidirectional control, and AI3 accepts 0-20mA current signals for long-distance transmission. One analog output (configurable as 0-10V or 0-20mA) allows the drive to send status signals such as motor current, frequency, or power to a PLC or panel meter. Six discrete inputs accept 24V DC signals from sensors, pushbuttons, or PLC outputs, with both positive and negative logic compatibility. Two relay outputs (R1: NO/NC contacts, R2: NC contact) provide dry contacts rated at 5A resistive, suitable for driving contactors, pilot lights, or alarms directly.

        The ATV312HU40N4 SCHNEIDER Variable Speed Drive may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        • Required Hardware (Multi-Loader): Firmware packages can only be applied using the dedicated Schneider Electric VW3A8121 Multi-Loader tool paired with the appropriate interface cables (such as the VW3A8122 patch cord) connected directly to the drive’s front RJ45 Modbus port.
        • Integrated Navigation Dial: The front panel features a bright 4-digit LED window accompanied by a centralized rotary selector button allowing direct "turn-to-select, click-to-enter" navigation through parameter codes.
        • SoMove Configuration Software: PC-based parameter management can be conducted via the free Schneider Electric SoMove tool. A dedicated Modbus-to-USB adaptation cable (e.g., VW3A8106) is required to bridge the PC's USB port to the drive's RJ45 communication port, unlocking graphical monitoring, parameter logging, and offline trace backups.
