Overview of the ALTIVAR 61 range

The ALTIVAR 61 series from Schneider Electric is dedicated to speed variation for variable-torque loads and process applications. It addresses the recurring needs of fluid handling and ventilation systems where fine speed adjustment delivers measurable energy savings and reduces mechanical stress. The availability of multiple sizes and power ratings supports retrofitting existing installations, providing functional continuity and controlled integration into automation architectures. Where flow or pressure regulation is critical, Altivar 61 is an established reference for driving low-voltage three-phase motors.

• ALTIVAR 61 : oriented to pumps, fans and site utilities, variable-torque control, reliable speed regulation and energy optimisation on 200...240 V networks or other variants depending on model within the range.
• ALTIVAR 71 : associated range for more dynamic drive applications with three-phase motors, when reinforced control functions are required in other industrial segments.

The ATV61HD45M3X model fits the Altivar 61 logic, with features suited to installations powered by three-phase 200...240 V and a 45 kW rating, suitable for variable-torque equipment requiring stable speed modulation and reliable integration into control cabinets.

Industrial applications

This Schneider Electric frequency inverter covers a wide spectrum of applications where speed control determines process performance. It is used for driving equipment with medium inertia and variable load, prioritising regulation quality, motor protection and compatibility with sequences controlled by a programmable logic controller and, where applicable, by numerical control systems for production cells.

• Industrial ventilation and HVAC : control of fans, extractors and cooling towers with V/f law adapted to variable load profiles.
• Process and utility pumping : supply, circulation and discharge in process loops, managing flow modulation according to demand.
• Material handling and light conveying : speed variation for conveyors, sorters and non-synchronised assembly lines.
• Air treatment and dust extraction : blowers, filtration fans and workshop air recycling.
• Food industry and site utilities : production auxiliaries requiring speed adjustment to stabilise the process and reduce mechanical jolts.

Integration and communication

The ATV61HD45M3X integrates into automation architectures via its local I/Os and by adding optional communication cards compatible with common industrial fieldbuses. This connectivity facilitates the exchange of setpoints and status with a programmable logic controller, enabling the inverter to be included in centralized control sequences and supervision systems. Available protocols depend on the modules installed and the integration project.

Commissioning is performed from the local operator panel and Schneider Electric configuration tools, with parameterisation of ramps, limits and protections in line with process requirements. Compatibility with architectures including numerical control and remote I/O modules simplifies adapting the drive to existing lines, while ensuring stable speed control, appropriate thermal protection for the motor and monitoring of electrical quantities for reliable technical diagnostics.
