The ABB KSD211B 3BHE022455R1101 is a high-performance Servo Drive Module designed for integration into the ACS880 multi-drive cabinet system from ABB. This module provides advanced, variable-speed motion control for synchronous and asynchronous servo motors, delivering high torque and precision for demanding industrial applications.
In a high-speed packaging line, a robotic arm must pick and place products onto a moving conveyor with millimeter precision. The ABB KSD211B servo drive module, installed within an ACS880 drive cabinet, receives a position command from the master controller via a high-speed fieldbus. It instantly processes the command and delivers the precise power required by the servo motor. The high dynamic response and accuracy of the KSD211B ensure the robot moves rapidly and stops exactly at the target location, maximizing throughput while maintaining flawless placement accuracy, which is critical for production efficiency.

The ABB KSD211B leverages the robust infrastructure of the ACS880 platform to deliver superior servo performance, characterized by several key innovations:
· •Innovation Point 1: ACS880 Common Platform Integration: A significant advantage of the KSD211B is its native integration into the ACS880 architecture. It shares common control interfaces, power supplies, and cooling systems with other drives in the cabinet. This simplifies system design, reduces spare part variety, and leverages the proven reliability and diagnostics of the ACS880 platform for servo applications.
· •Innovation Point 2: High-Performance Control Loop Technology: The module features extremely fast and precise current (torque) control loops. This high torque control bandwidth enables superior stiffness, smoother motion at low speeds, and higher accuracy in following demanding motion profiles, which is crucial for applications like precise tension control or rapid acceleration/deceleration.
· •Innovation Point 3: Comprehensive Safety and Diagnostics: The KSD211B incorporates integrated Safety Torque Off (STO) functionality, allowing safe disconnection of motor torque without additional hardware. Furthermore, it provides extensive software tools for advanced setup, oscilloscope functionality, and detailed diagnostics, enabling quick tuning and proactive issue identification to minimize downtime.
A metal processing plant operating a continuous casting line required precise control of the withdrawal rolls to prevent product defects. The existing drives struggled with speed synchronization, causing tension variations. By implementing ACS880 cabinet drives with ABB KSD211B servo modules for the critical withdrawal sections, the plant achieved perfect speed matching. The precise torque and speed control of the KSD211B modules eliminated tension spikes, resulting in a 50% reduction in product surface defects and a significant increase in yield, demonstrating a rapid return on investment.
