Protect the controller backup
Create and verify the available system backup before shutdown so robot programs, calibration data and controller settings are not dependent on the removed unit.

ABB DSQC639 3HAC025527-001 / DSQC639 3HAC025527-004 Computer Units
DSQC639 controller-computer records containing the processor platform, memory and cabinet cooling required by supported ABB robot systems.
01
Product Introduction
ABB DSQC639 3HAC025527-001 / DSQC639 3HAC025527-004 are computer-unit records for supported ABB robot controllers. The assembly contains the controller computer board, memory and cooling hardware that execute the robot operating system and application while exchanging commands and status with drive, I/O and teach-pendant interfaces.
Inside ABB DSQC639 3HAC025527-001 / DSQC639 3HAC025527-004, application and system data are handled by the computer board and RAM, while cabinet airflow removes heat from the processor assembly. Optional interface boards and external controller connections remain separate items and are transferred only when the documented upgrade or replacement procedure requires them.
When ABB DSQC639 3HAC025527-001 / DSQC639 3HAC025527-004 is replaced, controller backups and system identity are secured before power isolation. Antistatic handling, connector labels and fan-airflow checks precede the first boot; the controller is then checked for correct system load, communication and robot configuration.

03
Configuration and Programming
The computer unit hosts the controller software environment, but the installation record determines how that environment is restored to replacement hardware.
Restore the correct system
Load the controller-system version and robot configuration assigned to the machine rather than starting from an unrelated DSQC639 image.
Confirm interfaces after boot
Verify communication with drives, I/O and operator interfaces before any automatic cycle is permitted.
04
System Integration
DSQC639 sits at the controller's computing center and coordinates data paths rather than switching motor power directly.
Drive-system coordination
The computer supplies motion and enable information to the drive system and receives operating or fault state in return.
I/O and operator exchange
Controller I/O and teach-pendant data pass through assigned communication interfaces so commands and status are available to the running application.
Cooling and cabinet support
The integrated fan path supports the processor assembly; blocked airflow or an incorrectly seated cabinet can affect the whole controller rather than one channel.

Product Questions
What should be backed up before replacing ABB DSQC639 3HAC025527-001 / DSQC639 3HAC025527-004?
Back up the controller system, robot programs, calibration data and configuration before replacing ABB DSQC639 3HAC025527-001 / DSQC639 3HAC025527-004.
Why is ESD control important for ABB DSQC639 3HAC025527-001 / DSQC639 3HAC025527-004?
ABB DSQC639 3HAC025527-001 / DSQC639 3HAC025527-004 contains computer and memory electronics that can be damaged by electrostatic discharge.
Can optional boards be assumed to be included with ABB DSQC639 3HAC025527-004?
No. Optional interface boards for ABB DSQC639 3HAC025527-004 are handled according to the controller replacement or upgrade record and should not be assumed from the computer-unit name.
What should be checked on the first boot of ABB DSQC639 3HAC025527-001?
Confirm the correct system load, robot identity, drive communication, I/O communication, teach-pendant connection and cooling operation on ABB DSQC639 3HAC025527-001.
Does ABB DSQC639 3HAC025527-001 switch motor power?
No. ABB DSQC639 3HAC025527-001 executes controller software and coordinates interfaces; separate drive hardware switches motor power.
Why must the complete ABB DSQC639 3HAC025527 record be checked?
The -001 and -004 records can belong to different replacement or upgrade paths, so the complete ABB DSQC639 3HAC025527 identifier and controller revision must be retained.
