System Architecture & Signal Flow
This motor unit interfaces with the ABB robot controller (IRC5 / S4C+) via the axis computer board and drive module. The servo motor receives velocity and torque commands from the axis computer, executes motion through the pinion-gear transmission, and returns encoder feedback (resolver or absolute encoder) to close the position loop. The integrated pinion meshes directly with the robot joint gear ring, transmitting rotary motion to the robot arm segment.
Signal Path: IRC5 Controller → Drive Module → Motor Power & Encoder Cable → 3HAC044513-001 Motor → Pinion → Joint Gear Ring → Robot Arm Axis
