Why Engineers Specify This Model
- Dedicated HVAC/Pump Profile — Pre-configured macros for pump and fan applications reduce commissioning time to under 30 minutes.
- Energy Savings — Quadratic V/f law reduces motor energy consumption by up to 50% at partial loads versus direct-on-line starters.
- Integrated EMC Filter — Built-in Class C2 EMC filter eliminates the need for an external filter in most panel designs.
- Compact Footprint — Slim profile (72 mm wide) allows high-density panel layouts without sacrificing thermal performance.
- Modbus RTU Native — Standard RJ45 Modbus port enables direct integration with BMS, SCADA, and PLC networks without additional gateways.
- Auto-tuning — One-button motor auto-tuning optimizes drive parameters for the connected motor automatically.
- Robust Protection — Thermal overload, overcurrent, overvoltage, undervoltage, and phase-loss protection are all built in.
Complete System Bill of Materials
For a fully functional ATV310HU55N4 installation, engineers typically specify the following complementary components:
- Input Line Reactor — Reduces harmonic distortion and protects against supply transients (e.g., VW3A4551).
- Output dV/dt Filter — Protects motor windings on long cable runs (e.g., VW3A4601).
- Braking Resistor — Required for high-inertia loads with frequent stopping (e.g., VW3A7701).
- Remote Keypad / Display — Panel-mount remote display for operator interface (e.g., VW3A1101).
- CANopen Communication Card — For CANopen network integration (e.g., VW3A3608).
- Schneider GV2 / GV3 Motor Starter — Upstream motor protection circuit breaker.
- 24 VDC Power Supply — For control circuit and I/O power (e.g., ABL8REM24030).
Compliance & Industry Standards
- CE Marked — Compliant with EU Low Voltage Directive (2014/35/EU) and EMC Directive (2014/30/EU)

Application-Specific FAQ
Q: Can the ATV310HU55N4 control a pump in a closed-loop PID configuration?
A: Yes. The Altivar 310 has an integrated PID controller that accepts a 4–20 mA or 0–10 V feedback signal from a pressure or flow transducer, enabling closed-loop pump control without an external PLC.
Q: Is an external EMC filter required for CE compliance?
A: No. The ATV310HU55N4 includes a built-in Class C2 EMC filter, meeting EN 55011 requirements for most industrial environments. For residential or light commercial environments (Class C1), an additional external filter may be required.
Q: What is the maximum motor cable length supported?
A: Up to 50 m shielded cable without an output filter. With a dV/dt output filter, cable runs up to 100 m are supported.
Q: Can this drive be used with a single-phase input supply?
A: No. The ATV310HU55N4 (N4 suffix) is rated for 3-phase 380–460 V input only. For single-phase 200–240 V applications, refer to the ATV310HU55M2 variant.
Q: Does the drive support bypass operation?
A: The drive itself does not include an integrated bypass. A separate bypass contactor circuit must be designed into the panel if bypass-to-DOL operation is required.
Q: What communication protocols are natively supported?
A: Modbus RTU via RJ45 is native. Optional plug-in communication cards add CANopen, DeviceNet, PROFIBUS DP, or EtherNet/IP capability.
