Product Overview
The Schneider ATV61HD45N4 is a 45 kW variable speed drive from the Altivar 61 family, designed primarily for three-phase motor control in variable-torque applications such as pumps, fans, compressors, and industrial ventilation systems. It is rated for 380–480 VAC three-phase input and a 45 kW motor, with a nominal 60 hp rating at 460 V. The drive integrates Modbus and CANopen communication and supports optional industrial communication cards. Schneider specifies the ATV61 family for applications requiring controlled motor speed, energy management, and motor protection, with integrated EMC filtering and a wide range of configurable control functions.

Key Features and Benefits — ATV61HD45N4
- 45 kW motor capacity for high-power industrial drive applications.
- Three-phase 380–480 VAC supply range.
- Integrated Modbus and CANopen communication for PLC and DCS connectivity.
- Adjustable output frequency up to 500 Hz.
- Motor thermal, overcurrent, short-circuit, phase-loss, and DC-bus protection functions.
- Supports optional Ethernet, Profibus, DeviceNet, and other communication interfaces through expansion cards.
- Designed for variable-torque machinery where controlled acceleration, deceleration, and operating speed are required.
Personally, I would check the motor nameplate current and the actual application duty before selecting a replacement. A 45 kW rating by itself does not guarantee that the drive is correctly sized for every motor, especially where overload or high-temperature operating conditions are involved.

Installation and Maintenance — ATV61HD45N4
Install the drive vertically in a suitable control cabinet with adequate airflow and clearance. Verify input voltage, motor current, grounding, braking requirements, EMC configuration, and control wiring before energization. Schneider provides installation documentation specifically covering the 0.37–90 kW ATV61 range.
During maintenance, inspect cooling paths, power terminals, DC-bus connections, fans, control terminals, and communication ports. Record the existing parameter set before replacement, then verify motor data, acceleration/deceleration ramps, current limits, communication addresses, and application-specific control settings.
Product Warranty — ATV61HD45N4
Warranty coverage depends on supplier condition and sales terms. Confirm whether the drive is new, refurbished, or surplus and request serial-number traceability, functional-test results, parameter backup availability, and warranty documentation.
The Schneider ATV61HD45N4 is now a legacy Altivar 61 product; Schneider identifies the range as discontinued, so exact-part replacement and parameter compatibility are important for maintaining existing installations.
