ATV61HU22M3 - Speed drive - SCHNEIDER ELECTRIC

SCHNEIDER ELECTRIC frequency converter ATV61HU22M3 - ALTIVAR 61

The ATV61HU22M3 model is part of the Altivar 61 series from SCHNEIDER ELECTRIC, a range designed to control the speed of asynchronous and synchronous motors in industrial and commercial utilities. With a nominal power of 2,2 kW (3 CV) and a 240 V three-phase supply, this drive effectively meets the needs of ventilation, pumping and machine drives operating at constant or variable duty. The protection rating IP20 and the without CEM filter version suit integration in electrical enclosures where electromagnetic filtering is handled at installation level. The factory switching frequency of 4 kHz provides a robust compromise between performance, losses and heating. The ATV61HU22M3 simplifies maintenance with a structured commissioning process covering wall mounting, motor connection, supply, control and speed setpoint. The product lifecycle is known: production discontinued on 01/01/2017, end of service on 01/01/2025, with recommended replacement by the Altivar Process series ATV630U22M3 or ATV630U30M3 to ensure long-term support of installations.

Overview of the ALTIVAR 61 range

The Altivar 61 series has been installed in many process and building applications for energy optimisation and flexible control. It is particularly suited to utilities such as fans, pumps and circulators, where speed reduction directly controls consumption according to the affinity laws. This large installed base ensures maintainability, parts availability and field feedback from service teams. For modernisation projects, the replacement range Altivar Process ATV630 retains the core features of the ATV61 with energy-oriented and diagnostic functions, enabling a gradual migration in stages without changing the existing automation architecture.

• Altivar 61 : Drives intended for process utilities, ventilation and pumping, designed for panel integration, configuration focused on flow and pressure according to application.
• Altivar Process ATV630 : Recommended as the successor to the ATV61, electrical and logical compatibility, new service and energy efficiency features.

The ATV61HU22M3 sits at the heart of these applications, with a 240 V three-phase electrical configuration and a 2,2 kW power rating, commonly required for fan sets and small centrifugal pumps.

Industrial applications

The reference ATV61HU22M3 is aimed at integrators, operators and maintenance teams seeking stable control, soft starting and easy adaptation to load conditions. Typical uses include :

• HVAC ventilation : Control of supply and extract fans, speed adjustment for comfort and energy savings.
• Process pumping : Control of flow and pressure on centrifugal pumps, reduction of water hammer using acceleration ramps.
• Water treatment : Driving booster pumps and agitators, control via analog setpoint from controllers.
• Light conveying and machinery : Speed adjustment on conveyors, dosing machines and auxiliary equipment where steady speed is prioritised over dynamics.
• Plant rooms : Chilled water boosters, circulators and cooling towers controlled in variable speed.

Integration and communication

The ATV61HU22M3 integrates into IP20 electrical panels with standard supply and motor wiring. Setpoints can be provided by a programmable logic controller via I/Os or, depending on the equipment, via communication interfaces from the range. This integration allows speed control according to flow, pressure or temperature control loops supervised in the process digital control.

Commissioning follows an operational sequence: motor parameters, frequency limits, acceleration ramps, command and setpoint sources, thermal protections. Control by frequency variation ensures smooth operation of the motor and mechanical equipment, reduces airflow noise on fans and extends bearing life. Controlled stop and restart functions contribute to installation availability.

Availability and warranty

Standard Exchange Industry offers the ATV61HU22M3 new or refurbished depending on stock, as well as as exchange units and electronic repair. Each refurbished unit is bench-tested, and our services come with 6 to 24 months warranties depending on the service. Shipping is arranged within 24 to 72 h to over 120 countries to meet line-stop constraints. For installations undergoing migration, the replacement references ATV630U22M3 or ATV630U30M3 are recommended. Our technical teams can validate electrical and functional compatibility and assist with parameter adaptation. This pragmatic approach ensures continuity of service while preparing a progressive modernisation of drive systems.
