ATV61HU75M3 - Speed drive - SCHNEIDER ELECTRIC

SCHNEIDER ELECTRIC frequency drive ATV61HU75M3, Altivar 61

The ATV61HU75M3 frequency drive is part of the Altivar 61 range from SCHNEIDER ELECTRIC. Engineered for energy management and speed control of asynchronous and synchronous motors, it meets the needs of industrial utilities and continuous processes. Its rated power is 7,5 kW (10 CV) and it accepts a 200-240 V single- or three-phase supply, 50/60 Hz, to drive a 200-240 V three-phase motor. The integrated EMC filter supports electromagnetic compatibility in industrial settings. The IP20 protection rating is suitable for cabinet or protected plant-room installation, with wall mounting or panel mounting depending on workshop practices. The typical sound level is 57,4 dB, which helps when positioning near operators. The nominal output current is around 40,1 A at 50 °C for a switching frequency of 4 kHz, a value representative of steady-state behaviour. If used outside factory thermal settings, a derating may be required to prevent overheating. Typical dimensions for this drive format are approximately 295 mm in height and 213 mm in depth, simplifying integration into standard cabinets. This model fits distributed automation architectures where speed stability, reliability and repeatability are priorities, delivering measurable energy savings under the typical load profiles of pumps and fans.

Overview of the Altivar 61 range

The Altivar 61 series is dedicated to speed control of variable- and constant-torque drives in utilities and continuous processes. It is widely used in industrial HVAC, water treatment, food processing, fine chemistry and material handling installations. Altivar 61 drives favour structured commissioning, stable operation and control of energy consumption across the typical load profiles of pumps and fans. Their design supports cabinet integration, with a clear control architecture, EMC filtering included on many versions and protections adapted to industrial environments.

• Altivar 61, utilities and HVAC : focused on pumps, ventilation, compression and conveying, with speed control functions suited to variable loads and continuous operation.
• Altivar 61 in industrial processes : integration into automated lines, PLC control and supervision, with extension options for I/O and communications as required.

The ATV61HU75M3 model fits this performance-driven approach, with a voltage range dedicated to 200-240 V networks and a 7,5 kW power rating suited to medium-capacity machines requiring reliable regulation in steady-state operation.

Industrial applications

The Altivar 61 drive reference ATV61HU75M3 covers a wide range of applications where speed stability, reduced inrush currents at start-up and energy optimisation are essential. It is well suited to lines where constant flow, pressure or air flow is critical to process quality and equipment safety.

• Centrifugal and positive-displacement pumps : flow and pressure control, limiting water hammer and pressure surges using acceleration ramps.
• Ventilation and AHU : fan speed variation to adjust air flow in industrial HVAC.
• Conveyors and continuous handling : speed control and simple section-to-section synchronization.
• Water and wastewater treatment : control of lift, aeration and dosing pumps.
• Food processing : drives for mixing, transfer and packaging with controlled speed.

Integration and communication

The ATV61HU75M3 drive integrates into new or existing automation architectures. Local control is possible via the operator panel and remote control via a programmable logic controller or a SCADA system, using the standard control links of the range. Optional communication cards are available within the Altivar 61 family for integration on industrial fieldbuses, improving status reporting, diagnostics and setpoint management in multi-vendor architectures.

Commissioning is performed through structured parameterisation of the speed setpoint, acceleration and deceleration ramps, and thermal protection thresholds in line with the connected motor. Observing cable cross-sections, the grounding scheme and power and control wiring rules is essential to ensure EMC compliance and system reliability. Wall mounting and cabinet layout must account for the recommended clearances and thermal conditions; a derating may be required beyond factory settings to avoid excessive temperature rise.
