ABB ACS800-104-0440-7+E205+Q967+V991
ABB ACS800-104-0440-7 Single Drive Module (with specific options)
Product Description
The ABB ACS800-104-0440-7 is a powerful and versatile single drive module from ABB’s renowned ACS800 series of industrial drives. The ACS800 family is known for its Direct Torque Control (DTC) technology, which provides highly accurate and dynamic motor control, ensuring excellent performance even in demanding applications.
This specific module, the ACS800-104-0440-7, is designed as a cabinet-built, low harmonic drive, meaning it’s intended to be integrated into a larger control cabinet. It’s engineered to minimize harmonic distortion back into the power supply network, which is crucial for maintaining power quality in industrial environments.
It’s suitable for a wide range of industrial applications requiring precise speed, torque, and position control for AC motors, including:
- Pumps and fans

- Conveyors
- Extruders
- Mixers

- Cranes
- General machinery
The presence of the options +E205, +Q967, and +V991 indicates specific factory configurations or added functionalities:
- +E205 (Safe Torque Off – STO): This is a critical safety function that prevents unintended motor startup. When activated, it removes power from the motor windings, ensuring the motor cannot produce torque. This feature is vital for machine safety and compliance with international standards like EN/IEC 61800-5-2.
- +Q967 (Customer specific documentation/software): This option suggests that the drive comes with tailored documentation or pre-loaded software specific to a customer’s unique requirements or application.
- +V991 (EMC Filter Class C1): This option indicates that the drive includes an integrated Electromagnetic Compatibility (EMC) filter that meets Class C1 standards. This filter is designed to reduce electromagnetic interference (EMI) generated by the drive,
