ABB 3HAB5960-1 DSQC 322 Driver module

ABB 3HAB5960-1 DSQC 322

This is a single-axis servo drive module used to control the motors in robot joints. It is a key component of the internal drive unit of ABB robot controllers (such as the IRC5). It receives motion commands from the host computer and provides precise current and voltage to drive the servo motors, enabling precise positioning and movement of the robot.

Main Functions & Features

1. Single-Axis Drive:
   This module is dedicated to controlling one of the robot’s six (or more) joint axes. Typically, a complete robot system uses multiple such modules working in concert.

2. High-Performance Servo Control:

   • Utilizes advanced digital signal processing to ensure precise control of motor torque, speed, and position.

   • Provides high dynamic response, enabling the robot to perform acceleration, deceleration, and precise positioning quickly and smoothly.

3. Integrated into the IRC5 System:
   This module is designed for ABB’s fifth-generation robot controller, the IRC5. It connects via an internal bus to the main computer board, forming a complete motion control system.

4. Compact Modular Design:
   Features a standard modular structure for easy installation, replacement, and maintenance within the drive unit chassis, minimizing downtime.

5. Safety & Monitoring:
   The module incorporates numerous diagnostic and protection features, such as monitoring for overcurrent, overvoltage, undervoltage, overheating, and feedback system faults, ensuring the safe and stable operation of the robot system.
