The Altivar 71 is a robust variable speed drive designed for complex and high-power industrial machines, supporting both synchronous and asynchronous motors. It covers a wide power range from 0.37 kW up to 630 kW with supply voltages from 200–240 V single-phase and 200–690 V three-phase variants.

Key Features

• Advanced Motor Control: Offers sensorless flux vector control, flux vector control with sensor, and voltage/frequency ratio control with energy-saving adaptation for unbalanced loads.
• High Performance: Delivers high torque and speed accuracy even at very low speeds, with transient overtorque capabilities up to 220% of nominal motor torque.
• Extensive Functionality: Includes up to 50 integrated functions such as brake control for hoisting, load measurement, slack sling management, and limit switch handling, designed for demanding applications like hoisting and material handling.
• Flexible Communication: Standard Modbus and CANopen protocols with options for Modbus TCP, DeviceNet, PROFIBUS DP, and other industrial networks via communication cards.
• Safety and Standards: Compliant with IEC/EN 61800-5-1, IEC/EN 61800-3, UL, CSA, DNV, and others; includes functional safety features suitable for ATEX environments.
• User Interface: Integrated 7-segment display terminal or remote graphic display terminal for easy configuration and monitoring.
• Programming Ease: Supports macro-configuration and a Simply Start menu to facilitate quick setup and adjustment.

Applications

• Designed for demanding industrial drive systems including hoisting, handling, and complex automation tasks that require precise motor control and enhanced safety.

Additional Details
