ABB 3HAC1462-1 Axis Control Board

ABB 3HAC1462-1 Axis Control Board is the DSQC363 axis processor board used as the axis computer in ABB IRB S4C-series robots, serving as the dedicated processing unit that coordinates axis motion in legacy ABB controllers. Commonly listed under aliases 3HAC14621 and 3BSC980-006-R173, this module comes in a rack-mountable enclosure and provides a DE-9F serial port along with two 96-pin male connectors for I/O and peripheral interfacing, with LED indicators to aid field diagnostics. As the axis processor, it executes the computational tasks for servo control, integrating resolver feedback and axis commands within ABB's DSQC363 family to support precise motion of the robot's joints. Because ABB discontinued this exact board, current availability is typically limited to secondary markets or refurbished stock, so buyers should confirm compatibility with their IRB S4C configuration and the DSQC363 module before replacement.
