Why Choose the Original Model
- Proven ATV61 ecosystem: Seamless integration with existing Schneider Electric panels, PLCs (Modicon M340/M580), and SCADA systems without re-engineering.
- Pump & fan optimization: Built-in PID controller, sleep/wake function, and pipe-fill mode reduce commissioning time for HVAC and water treatment systems.
- Fieldbus flexibility: Optional communication cards (CANopen, Profibus DP, DeviceNet, Ethernet/IP) allow integration into virtually any industrial network.
- Established spare parts supply: Control boards, power cards, and fan assemblies remain available through authorized channels.
- Regulatory compliance: CE, UL, and cUL marks simplify export documentation and site acceptance testing.
Typical Applications
- Centrifugal pumps and booster pump stations (water supply, HVAC, irrigation)
- Axial and centrifugal fans (air handling units, cooling towers, exhaust systems)
- Compressors and blowers in process industries
- Conveyor systems requiring smooth speed ramp control
- Municipal water treatment and wastewater facilities
- Building management systems (BMS) with Modbus or BACnet integration
System Compatibility
- PLC / Controller: Modicon M340, M580, Premium, Quantum; Siemens S7 (via Profibus/PN card); Allen-Bradley (via DeviceNet/EtherNet/IP card)
- SCADA / HMI: Vijeo Designer, Wonderware, Ignition (via Modbus TCP/RTU)
- Motor types: Standard asynchronous induction motors (IEC frame); compatible with IE2/IE3 efficiency class motors
- Input line filters: VW3A4400 series EMC filters recommended for CE compliance in residential/light industrial zones
- Output chokes: VW3A4551 series dV/dt filters recommended for cable runs >50 m
Selection Guide
Use the following criteria to confirm the ATV61HD37N4 is the correct drive for your application, or to identify the most suitable alternative:
- Step 1 – Load type: ATV61 is optimized for variable torque (pumps/fans). For constant torque (conveyors, hoists), consider the ATV71 series.
- Step 2 – Motor power: Confirm motor nameplate kW ≤ 37 kW. For motors 45 kW and above, select ATV61HD45N4.
- Step 3 – Supply voltage: Verify 3-phase 380–480 V supply. For 200–240 V systems, select the ATV61HD37M3X variant.
- Step 4 – Environment: IP20 is suitable for clean control cabinets. For outdoor or dusty environments, specify IP54 enclosure (ATV61HD37N4S337) or add a protective enclosure.
- Step 5 – Communication: Standard Modbus RTU is built-in. Specify the required optional card (VW3A3301–VW3A3320 series) for Profibus, CANopen, or Ethernet.
- Step 6 – Upgrade path: If long-term support is a priority, evaluate the ATV630D37N4 as a drop-in successor with enhanced diagnostics and IIoT connectivity.

Replacement & Compatibility FAQ
Q: Is the ATV630D37N4 a direct drop-in replacement for the ATV61HD37N4?
A: Mechanically and electrically, yes — same power class and voltage range. However, parameter names and menu structure differ. A full re-commissioning is required. Mounting dimensions are similar but not identical; verify panel cutout before installation.
Q: Can I use a third-party brand (ABB, Siemens, Yaskawa) as a replacement?
A: Functionally yes, provided the power, voltage, and control interface requirements are matched. Expect full re-wiring of control terminals and re-commissioning. Fieldbus cards and PLC program modifications may also be needed.
Q: Is the ATV61HD37N4 still in production?
A: The ATV61 series has been superseded by the ATV630/ATV650 series. New production units are no longer manufactured, but genuine new-old-stock (NOS) and refurbished units remain available through specialist distributors such as Konmask.com.
Q: What is the warranty on units purchased from Konmask.com?
A: New/NOS units carry a 12-month warranty from date of shipment. Refurbished units carry a 6-month warranty. Extended warranty options are available — contact us for details.
Q: Do you provide technical support for installation and commissioning?
A: Yes. Our engineering team can provide parameter setup guidance, wiring diagrams, and remote commissioning support via email or video call.
