The DSQC 104 (6369901-104) is a specialized Resolver-to-Digital (R/D) conversion interface board designed for ABB industrial robot controllers. This module acts as the critical bridge between the robot's physical movement and its digital control system. It interfaces directly with motor-mounted resolvers on the robot’s axes, capturing analog sine and cosine feedback signals and translating them into high-precision digital position data for the motion CPU.
Engineered for the rigorous demands of robotic motion control, the DSQC 104 (6369901-104) provides superior signal conditioning and noise rejection. This ensures that even in environments with high electromagnetic interference—such as spot welding or heavy machining cells—the robot maintains exceptional joint positioning accuracy and trajectory repeatability. This board is essential for maintaining the operational integrity of 6-axis articulated arms and external axis units within the IRC5 and legacy ABB controller ecosystems.
