Features:
- High Overload Capacity for Heavy-Duty Applications
- Integrated Safety Function "Power Removal" (STO)
- Dual Communication Ports with Expandable Options
Schneider Electric ATV71HD55N4Z delivers 220% rated torque for 2 seconds and 170% for 60 seconds, making it ideal for high-inertia loads such as cranes, hoists, and extruders. This transient overtorque capability ensures stable operation during sudden load spikes, reducing unexpected downtime and mechanical stress on driven equipment.
The Schneider Electric ATV71HD55N4Z includes a dedicated safety input (PWR terminal) that implements a Safe Torque Off function compliant with EN 954-1 Category 3 and IEC/EN 61508 SIL2. This allows the drive to be directly integrated into safety circuits without external contactors, simplifying machine design and reducing panel wiring costs while meeting global machinery safety standards.
Standard with Modbus and CANopen, the Schneider Electric ATV71HD55N4Z also accepts optional communication cards including Profibus DP, Ethernet/IP, DeviceNet, and the "Controller Inside" programmable card. This flexibility enables seamless integration into mixed PLC environments (Siemens, Rockwell, Schneider) and supports future migration to Industrie 4.0 architectures without hardware replacement.
The ATV71HD55N4Z Schneider Electric Altivar 71 Series Variable Speed Drive may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Temperature Range Without Derating: The Schneider Electric ATV71HD55N4Z operates at full rated current from -10°C to 50°C (14°F to 122°F). For ambient temperatures up to 60°C, a control card fan kit is mandatory, with current derating of 2.2% per °C above 50°C.
- Altitude Adaptation: At altitudes from 1000m to 3000m, the drive requires a 1% current derating per additional 100m due to reduced air cooling efficiency. Above 3000m, use an external forced ventilation cabinet. The dielectric withstand voltage is factory-tested at 3535V DC between earth and power terminals, safe up to 4800m.
- Humidity & Condensation Resistance: With a relative humidity tolerance of 5…95% (non-condensing), the Schneider Electric ATV71HD55N4Z is suitable for humid environments such as textile mills or food processing. For applications with condensation risk, the IP54 mounting kit or enclosure heating is recommended.
- Vibration & Shock Resilience: Certified to IEC 60068-2-6 (1.5mm peak-to-peak, 1gn) and IEC 60068-2-27 (15gn shock), this drive withstands typical industrial vibration from stamping presses or mining conveyors without loosening terminals or degrading performance.
- Real-Time Torque & Current Logging: The Schneider Electric ATV71HD55N4Z provides analog output A01 (0-10V or 0-20mA) configurable to reflect motor current, torque, or power. This allows external PLCs or panel meters to monitor process load without additional sensors.
- Diagnostic Fault Log with Time Stamps: Up to 8 recent faults are stored in non-volatile memory with elapsed time stamps. Parameters FLT-1 through FLT-8 can be read via the display or Modbus, enabling root-cause analysis for intermittent issues like overvoltage or phase loss.
- Embedded PI Regulator for Process Control: The drive includes a configurable PI loop (parameter PIP group) that can directly regulate pressure, flow, or level using sensor feedback on analog input AI2. No external controller is needed for closed-loop pump or fan applications.
- Remote Monitoring via Modbus/CANopen: All operational parameters (speed, current, voltage, temperature) are accessible as Modbus registers or CANopen objects. A master PLC can read drive status every 10ms, while the "Controller Inside" option card allows custom condition monitoring scripts (e.g., bearing wear detection via speed ripple analysis).
- Heavy Lifting & Hoisting: The Schneider Electric ATV71HD55N4Z excels in overhead cranes, winches, and elevators where controlled starting/stopping and holding torque are critical. Its 220% overload capacity ensures safe handling of sudden load changes.
- High-Inertia Machinery: Centrifuges, decanters, and mixers benefit from the drive's flux vector control, which maintains speed regulation even with varying material loads. The built-in braking transistor (up to 150% with resistor) handles regenerative energy efficiently.
- Material Handling & Conveyors: Complex conveyor systems with multiple zones benefit from the CANopen interface, enabling synchronized speed profiles. The integrated PI regulator can directly control pressure or flow using external sensor feedback.
- Pump & Fan Control: In HVAC and pumping stations, the drive's energy adaptation (ENA) system optimizes efficiency by reducing magnetic flux at light loads, cutting energy use by up to 30% compared to fixed V/F control.
