The ATV71HD75N4 is a high-performance, three-phase variable speed drive within the Altivar 71 product range, built for heavy-duty industrial control. Operating on a rated input voltage of three-phase 380V to 480V AC, this drive delivers a continuous rated power output of 75 kW (100 HP) to manage the speed and torque of industrial asynchronous motors.
Delivers high startup torque at low speeds for rigorous hoisting and extrusion tasks
Features a metal heat sink and heavy-duty fans for reliable operation up to 1000m without derating
Built-in Class A EMC filter blocks electromagnetic noise to protect sensitive sensors nearby
The hardware configuration features an integrated heavy-duty metal heat sink combined with high-volume forced air cooling fans, ensuring optimal thermal equilibrium during high-load continuous operations and frequent startup cycles. Furthermore, this drive operates up to 1000 meters above sea level without derating, offering reliable field stability and durability across a standard working temperature range of -10°C to +50°C.
On the control and safety layer, the ATV71HD75N4 contains a built-in Class A integrated EMC filter to suppress conducted electromagnetic radiation and safeguard surrounding precise industrial electronics against signal interference. Its nominal switching frequency is established at 2.5 kHz, with an adjustable range spanning from 1 kHz to 16 kHz to adapt to various process loads.
The drive provides native embedded Modbus and CANopen serial communication bus protocols, enabling external master controllers (such as PLCs or DCS) to directly execute high-precision speed regulation and real-time status monitoring via digital networks. Additionally, it integrates multiple comprehensive safety safeguards, including motor overload protection, output short-circuit protection, input phase loss protection, and overvoltage/undervoltage interlocks, ensuring the reliable operation of rotating assets.

Mining & Extraction Industry
Soft-starting and multi-motor power-balancing control for heavy-duty belt conveyors and long-distance material transport lines to reduce mechanical shocks.
Oil & Gas Exploration & Production
Speed regulation for onshore oilfield beam pumping units (donkey heads) or mud pumps to optimize pumping frequency and displacement in real-time based on downhole conditions.
Iron & Steel & Metallurgy Industry
Speed control for rolling mill roller tables or blast furnace charging hoists to handle frequent, high-load forward/reverse rotations and rapid start/stop cycles.
Rubber & Plastics Processing
Main motor drive for large plastic/rubber extruders and internal mixers, delivering high constant torque to ensure stable extrusion pressure under high-viscosity material loads.
Chemical & Chemical Fiber Industry
Driving reactor agitation motors in highly corrosive or hazardous environments, as well as executing anti-surge speed adjustment for high-pressure centrifugal gas compressors.
Power & Energy Industry
Variable frequency speed control for boiler induced draft fans, primary air fans, or large circulating water pumps in thermal power plants to dynamically match air and water volume with power generation loads.
As it drives a high-power 75kW motor, strict monitoring of the cooling and ventilation environment is mandatory; ensure ample mounting clearance inside the cabinet and clean the heatsinks and fans regularly to prevent ambient overheating from triggering OCF (Overcurrent) or OHF (Drive Overheat) faults.
During wiring and commissioning, motor nameplate parameters must be accurately entered for precise vector control, and dynamic braking resistors must be correctly configured in constant-torque, heavy-duty applications to absorb regenerative energy.
Furthermore, field cabling must strictly adhere to electromagnetic compatibility (EMC) shielding standards, and given that this legacy model is now phased out, facilities should proactively prepare an upgrade and migration roadmap toward the Altivar Process ATV930 series.
