Variable speed drive doubles design life, has 200% torque, no feedback

Yaskawa America A1000 variable speed drive has three expansion ports and is compatible with a number of existing ports for increased versatility.


The Drives and Motion Division of Yaskawa America Inc. offers the A1000 variable speed drive, a full featured drive, reportedly providing outstanding quality, performance, flexibility, and environmental friendliness through 1000 hp. The new A1000, reportedly has a calculated design life that is twice as long as previous generations. Compatibility with interior and surface permanent magnet motors provides highly efficient, precision control with incredible performance, producing up to 200% torque with or without feedback.

User-friendly configuration tools, including a multi-language LCD display, parameter storage, application presets, and a portable USB copy unit make programming and configuration simple. DriveWizard computer software delivers configuration, monitoring, and trending functions enhanced by direct connectivity through the A1000’s standard USB port.

A significant quantity of control points are included as standard. For applications requiring more functionality, the A1000 offers three expansion ports for additional I/O, feedback, and network communications, including DeviceNet, EtherNet/IP, Modbus TCP/IP, Profibus-DP, Profinet, and Mechtrolink-II. Embedded applications functions, such as PID control, droop control, and function block programming provide system level control without the use of a stand-alone controller.

Energy efficiency is maximized with variable speed control, and A1000’s integrated dc reactors reduce harmonic demand from the power system, contributing to a cleaner environment. Additionally, all materials used in the A1000 comply with the directive for Restriction of Hazardous Substances (RoHS).

The A1000 drive is available in 200-240 V ac three phase 50/60 Hz (up to 175 HP), 380-480 V ac three phase 50/60 Hz (up to 1000 hp), and 500-600 V ac three phase 50/60Hz (up to 250 hp) ratings. In addition, the A1000 is designed for use around the world, and carries agency certifications for all major geographical regions.
