1. Product Overview

The ABB DSQC 104 is a Resolver Board used in ABB industrial robot controllers, such as the IRC5 series. It receives and processes resolver signals from servo motors to provide high-precision closed-loop feedback on motor position, angle, and speed. The module is a critical part of the robot servo control system, ensuring precise motion of joints and end-effectors. DSQC 104 provides reliable signal acquisition and conversion, delivering accurate positioning information for multi-axis robot systems.
