Product Overview

• PN: 3HAB8101-19
• Alias Part No: DSQC545A
• Brand: ABB
• Series: ABB IRC5 Robot Control System
• Type: Single Axis Servo Drive Module

• Function: This servo amplifier is installed inside IRC5 control cabinet. It receives motion commands from main computer board, drives one robot joint servo motor, completes speed regulation, position closed-loop control and current protection. It feeds back encoder position signals to the main control unit in real time to ensure accurate path tracking during robot welding, handling, painting and assembly tasks. Multiple drives work together to control each axis of the manipulator respectively.

Core Features

• Independent single-axis driving design, built-in current loop, speed loop and position loop triple closed-loop algorithm
• Integrated overcurrent, overvoltage, undervoltage, overheat and short-circuit multi-protection mechanism to prevent motor and drive damage during abnormal operation
• On-board status LED indicators to display power-on, running state and fault code for quick on-site troubleshooting
• Supports hot swap replacement under cabinet power-off condition, directly pluggable into IRC5 backplane slot
• Industrial grade power circuit with strong anti-interference ability, adapts to workshop long-term continuous heavy-duty operation

• Version DSQC545A is a mature upgraded revision with optimized heat dissipation and fault diagnosis logic compared with early versions
