Features:
- Provides 170% torque for 60 seconds and 220% for 2 seconds, with 323A/355A transient current capability, ideal for high-inertia loads like crushers, extruders, and centrifuges.
- Supports sensorless flux vector control (SFVC), flux vector control with encoder (FVC), and V/F ratio for both asynchronous and synchronous motors. Speed range up to 1:1000 closed-loop with ±0.01% accuracy.
- Includes Safe Torque Off (STO) conforming to ISO 13849-1 level d, response time ≤100ms. Built-in EMC filter meets EN 61800-3 category C3, simplifying cabinet installation.
The ATV71HC11N4 is engineered for the most demanding industrial applications requiring exceptional overload capability. Under normal duty, it delivers 215A continuous output current with 110kW (150HP) motor power. When applications demand more, the drive provides 170% of nominal motor torque for 60 seconds and an astonishing 220% for 2 seconds. Transient current capability reaches 323A for 60 seconds and 355A for 2 seconds, making the ATV71HC11N4 ideal for high-inertia loads such as crushers, ball mills, extruders, centrifuges, and heavy-duty hoists.
The ATV71HC11N4 offers sophisticated motor control algorithms to optimize performance for any application. Sensorless flux vector control (SFVC) provides high torque accuracy (±15%) and speed regulation (±10% of slip) without an encoder, suitable for most industrial processes. For maximum precision, flux vector control (FVC) with encoder feedback delivers ±0.01% speed accuracy and ±5% torque accuracy, with a speed range of 1:1000. The drive also supports voltage/frequency ratio control (2 or 5 points) for simple fan and pump applications.
The ATV71HC11N4 simplifies system design and enhances safety with integrated functions that would otherwise require external components. The Safe Torque Off (STO) function, conforming to ISO 13849-1 level d, provides a hardware-based safety path that prevents unexpected motor start. Response time is ≤100 ms from safety input to output removal. The drive can be integrated with Preventa XPS AC or XPS ATE safety modules for applications requiring category 3 or SIL2 per IEC/EN 61508, with wiring diagrams provided for emergency stop (category 0) and controlled stop (category 1) configurations.
The ATV71HC11N4 SCHNEIDER Variable Speed Drive may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL)by the manufacturer (OEM).

- Hoisting & Material Handling: Powers the main hoist mechanisms, gantry travel, and trolley motions of heavy industrial cranes. It features a patented Brake Logic Control algorithm that coordinates the motor torque and mechanical brake to completely eliminate "load sag" or slipping during starts and stops.
- Mining & Bulk Materials: Drives heavy-duty conveyor belts, ball mills, stone crushers, shredders, and high-capacity mixers that require massive starting torque under full load.
- Metal & Steel Processing: Deployed in continuous wire drawing machines, metal extruders, uncoilers, and complex slitting lines where precise tension control and master-slave load sharing are mandatory.
- Firmware Architecture: The embedded firmware governs the motor's mathematical algorithms (such as the voltage vector and current loops) and communication stacks. Upgrades are usually implemented to patch fieldbus communication vulnerabilities or to support newer network expansion modules.
- Flash Update Tools: Unlike modern IIoT drives that use web servers, updating an ATV71 requires a dedicated hardware bridge—specifically the Schneider Modbus-to-USB serial cable (TSXCUSB485). The flash procedure is executed via SoMove or legacy PowerSuite software on a PC.
- Safety Critical Step: Firmware flashing must only be performed when the motor is at a complete standstill and the high-voltage main mains are safely isolated. Flashing forces the drive back to factory default parameters, meaning the existing configuration (.psf or .smv file) must be fully backed up to a computer beforehand..
- The detachable LCD keypad features an intuitive "Simply Start" menu designed for rapid commissioning.By entering the motor nameplate data (kW, Voltage, Amps, RPM) and executing an Auto-Tuning routine, the drive maps the internal stator resistance and instantly optimizes its vector control model.
- Engineers use the free SoMove software via a physical serial wire or a Bluetooth module (VW3A1103).The platform unlocks access to over 150 advanced parametric tweaks, allowing users to configure 16 pre-set speeds, dual motor profiles, customized acceleration/deceleration S-ramps, PID loops, and skip frequencies to avoid mechanical resonance.
- This module transforms the ATV71 from a simple drive into a standalone automation node. By slotting the VW3A3501 Programmable Card (which has its own microprocessor and memory) into the drive, users can write localized code.
