Why Engineers Specify This Model
- Dual-Model Compatibility: ATV61 and ATV71 share the same power stage and mounting footprint — simplifying spare-parts inventory and enabling cross-series replacement during MRO.
- Advanced Motor Control: The ATV71’s closed-loop flux vector control delivers ±0.01% speed accuracy, critical for tension-sensitive and positioning applications.
- Energy Savings: Built-in Energy Saving Mode (ESM) on the ATV61 reduces motor energy consumption by up to 30% on variable-torque loads (pumps, fans).
- Integrated EMC Filter: Class C2 filter eliminates the need for external EMC components, reducing panel space and BOM cost.
- Rich Communication Stack: Native Modbus RTU and CANopen with optional fieldbus cards (Profibus DP, DeviceNet, EtherNet/IP, Modbus TCP) for seamless PLC/SCADA integration.
- Safe Torque Off (STO): ATV71 includes SIL 2 / PLd-rated STO function for machinery safety compliance without external contactors.
- Compact Footprint: Book-style mounting enables high-density panel layouts in space-constrained enclosures.
Complete System Bill of Materials

Application-Specific FAQ
Q: Can the ATV61HU75N4 replace the ATV71HU75N4Z directly?
A: For most pump and fan applications using V/f or sensorless vector control, yes — the ATV61HU75N4 is a direct functional replacement. The ATV71 is required for closed-loop encoder feedback, STO safety function, or applications needing higher dynamic performance.
Q: What is the maximum motor cable length?
A: Without output filter: up to 50 m shielded. With VW3A4420 dV/dt filter: up to 100 m. Longer runs require engineering review.
Q: Is this drive compatible with IE3 / IE4 premium efficiency motors?
A: Yes. Both ATV61 and ATV71 support auto-tuning for IE3/IE4 motors. The ATV71’s flux vector mode further optimizes efficiency at partial loads.
Q: Can I use this drive in a multi-pump configuration?
A: Yes. The ATV61HU75N4 includes a built-in PID controller and multi-pump sequencing logic (up to 6 pumps) without requiring an external PLC.
Q: What fieldbus is required for Siemens S7 PLC integration?
A: Profibus DP (option card VW3A3310) or Modbus TCP via Ethernet card (VW3A3316) are the most common choices for S7-300/400/1500 integration.
Q: Do you provide a warranty?
A: Yes — 12-month warranty against manufacturing defects. Warranty claims processed within 5 business days of receipt.
