Integration of Inertial Labs’ MRU with ABB ACS880 Winch Drives

Inertial Labs Motion Reference Unit (MRU) is now fully integrated with ABB ACS880 winch drives for Offshore AHC and Towing Roll Compensation.

Inertial Labs, renowned as one of the most advanced motion sensor manufacturers, has consistently showcased its commitment to innovation and technological adaptation. As part of its forward-thinking approach, the company has taken a significant stride in diversifying its MRU (Motion Reference Unit) range. Recognizing the evolving demands of the industry, Inertial Labs has seamlessly integrated the MODBUS TCP protocol, ensuring enhanced communication capabilities. This strategic incorporation is tailored to ensure optimal compatibility and interaction with the ABB ACS880 winch drive, a benchmark in its category. This integration not only emphasizes Inertial Labs’ dedication to interoperability and modern solutions but also fortifies the promise of delivering unparalleled performance and user experience to its clients. By anticipating industry trends and aligning with leading-edge systems like ABB ACS880, Inertial Labs strengthens its position as a visionary in the motion sensors domain.


ABB ACS880 winch drives for offshore applications now offer embedded software for applications involving Active Heave Compensation (AHC) and Roll Compensation in Towing. This eliminates the need for costly external third-party controllers and reduces wiring time and cost. Inertial Labs MRUs were selected as partners by ABB for offshore applications used for their innovation, R&D, and support. Their Graphical User Interface (GUI) is user-friendly to efficiently configure the MRU, which offers superior performance for standard and customized applications. The combination of ABB ACS880 winch drives with Inertial Labs MRU enables easy integration and requires no engineering time to develop communications, allowing the user to concentrate on the application.


ABB ACS880 winch drive and Inertial Labs MRU communicate over Ethernet Modbus TCP protocol with a watchdog timer for a failsafe system. Each MRU can communicate with up to two ACS880 drives in parallel for redundancy or as master/follower synchronized applications.
