Features:
- Heavy-Duty Overtorque Capacity for Demanding Applications
- Integrated EMC Filter for Simplified Installation
- Flexible Motor Control with Multiple Profiles
Schneider Electric ATV71HU55N4Z delivers 170% of nominal torque for 60 seconds and 220% for 2 seconds, ensuring reliable operation during sudden load spikes or high-inertia starts. This capability is critical for applications like cranes, elevators, and conveyors where momentary overloads are common.
With a built-in Class A EMC filter, Schneider Electric ATV71HU55N4Z meets EN 55011 Class A Group 2 and EN 61800-3 standards without requiring external filtering components. This reduces panel space requirements, lowers installation costs, and simplifies compliance with electromagnetic compatibility regulations.
Schneider Electric ATV71HU55N4Z supports five control modes including sensorless flux vector control and flux vector control with encoder feedback. This flexibility allows the same drive to optimize performance for different motor types (synchronous/asynchronous) and application requirements, from simple V/F control for pumps to high-precision torque control for hoisting.
The ATV71HU55N4Z Schneider Electric Altivar 71 Variable Speed Drive may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Precision Speed Regulation – Schneider Electric ATV71HU55N4Z achieves ±0.01% speed accuracy in closed-loop mode with encoder feedback, ensuring consistent process output even under varying load conditions. For open-loop applications, slip compensation automatically adjusts output frequency to maintain target speed within ±10% of nominal slip.
- Energy Optimization for Unbalanced Loads – The ENA (Energy Adaptation) system in Schneider Electric ATV71HU55N4Z continuously adjusts motor flux based on real-time load requirements, reducing energy consumption by up to 30% compared to fixed V/F control during partial load operation.
- Extended Speed Range – Open-loop asynchronous motor operation with Schneider Electric ATV71HU55N4Z covers a 1:100 speed range, while closed-loop operation with encoder feedback extends to 1:1000. This wide range enables precise low-speed control down to 0.1 Hz without cogging.
- Adjustable Switching Frequency – Users can tune the switching frequency of Schneider Electric ATV71HU55N4Z from 1 to 16 kHz to balance audible noise reduction and electromagnetic emissions. Higher frequencies reduce motor noise at the cost of increased drive losses and derating requirements above 4 kHz.
- Broad Temperature Operation – Schneider Electric ATV71HU55N4Z functions continuously from -10°C to +50°C (14°F to 122°F) without performance derating, with storage capability from -25°C to +70°C (-13°F to 158°F) for inventory flexibility.
- Contaminant Resistance – Certified to IEC 60721-3-3 Class 3C1 (chemical gases) and Class 3S2 (suspended particulates), Schneider Electric ATV71HU55N4Z withstands industrial environments containing low levels of corrosive gases and non-conductive dust without additional protection.
- Multiple Protection Ratings – Base configuration of Schneider Electric ATV71HU55N4Z is IP20 (finger-safe protection for control panel installation). Optional kits upgrade protection to IP21 (drip-proof), IP41 (tool-safe with vertical drip protection), or IP54 (dust-protected with splash resistance).
- Altitude Tolerance – Standard operation of Schneider Electric ATV71HU55N4Z is certified up to 1000 meters (3280 feet) at full rating. For installations up to 3000 meters (9842 feet), linear current derating of 1% per 100 meters ensures continued reliable operation in high-altitude facilities.
- Lifting and Hoisting Equipment – The 220% overtorgue capacity of Schneider Electric ATV71HU55N4Z ensures safe, controlled starts and stops for overhead cranes, hoists, and elevators. Precise speed control at zero speed with holding torque eliminates load drifting during operation.
- Material Handling and Conveyor Systems – Consistent torque delivery across the entire speed range makes Schneider Electric ATV71HU55N4Z ideal for baggage handling, warehouse conveyors, and assembly lines where product flow must remain steady regardless of load variation.
- Packaging and Textile Machinery – High dynamic response and 16 preset speeds enable Schneider Electric ATV71HU55N4Z to handle rapid production changes in packaging lines and textile manufacturing, where acceleration/deceleration profiles must synchronize with upstream and downstream equipment.
- High-Inertia Machinery – Centrifuges, mixers, and extractors with significant rotational mass benefit from the controlled deceleration ramps and braking capabilities of Schneider Electric ATV71HU55N4Z, preventing mechanical stress and process disruption during stops.
