ABB ACS800 – 104 – 0440 – 7+E205+Q967+V991 Variable Frequency Drive Module

The ABB ACS800 – 104 – 0440 – 7+E205+Q967+V

991 is a high – performance variable frequency drive (VFD) module from ABB’s ACS800 series. This drive is designed to control the speed and torque of three – phase AC motors in a wide range of industrial applications.

The ACS800 series is known for its advanced direct torque control (DTC) technology, which provides accurate and rapid motor control. The DTC technology allows for precise speed regulation, high – torque performance even at low speeds, and excellent dynamic response. It can handle various types of motors, including standard induction motors and permanent magnet motors.

The model number suffixes represent additional options and features. For example, the “E205” might refer to a specific communication option, enabling seamless integration with other devices in an industrial network. The “Q967” and “V991” could represent other custom – added features such as additional protection functions, enhanced user interfaces, or specific application – oriented settings.
