ABB DSQC617 3HAC025338-001 / DSQC617 3HAC025338-004 Main Servo Drive Units
Two DSQC617 main-drive executions for ABB robot-controller motor-channel configurations.
01
Product Summary
ABB DSQC617 3HAC025338-001 / DSQC617 3HAC025338-004 are main servo drive units used in documented ABB robot-controller drive configurations. The units receive controller drive commands, convert DC-link energy into regulated motor output and return drive-state information to the controller so commanded robot motion and monitored drive condition remain connected.
The channel execution distinguishes ABB DSQC617 3HAC025338-001 / DSQC617 3HAC025338-004. Ordering number 3HAC025338-001 is identified as D6 3B 3A, while 3HAC025338-004 is identified as D6 3G3T; the exact version is matched to the controller cabinet wiring, connected motors and feedback interfaces.
Before ABB DSQC617 3HAC025338-001 / DSQC617 3HAC025338-004 is serviced, mains and DC-link energy are isolated and the drive connectors are labeled. After exchange, the controller drive configuration, connected axes and fault-free enable sequence are verified at controlled speed rather than assumed from cabinet fit alone.

03
Monitoring and Control
The DSQC617 combines command processing, motor-energy conversion and controller feedback inside one main-drive path.
Regulate motor output
The power stage switches DC-link energy into the controlled motor phases assigned by the D6 channel execution.
Return drive state
Enable, fault and operating information returns to the controller so axis commands can be inhibited or diagnosed when the drive path is not ready.
04
Diagnostics and Protection
Service checks separate incoming energy, drive electronics and connected motor channels before a replacement unit is enabled.
DC-link state check
Verify the specified discharge interval and confirm the DC link is safe before touching terminals or releasing the unit.
Connector and channel check
Compare every labeled power and feedback connector with the selected 3B 3A or 3G3T execution before energization.
Fault-free enable check
Restore power with the robot restrained, confirm the controller recognizes the drive and clear only faults whose wiring and axis cause has been verified.

Customer Questions
What is different between ABB DSQC617 3HAC025338-001 and DSQC617 3HAC025338-004?
ABB DSQC617 3HAC025338-001 is the D6 3B 3A execution, while ABB DSQC617 3HAC025338-004 is the D6 3G3T execution.
Can ABB DSQC617 3HAC025338-001 / DSQC617 3HAC025338-004 be selected by cabinet fit?
No. Match ABB DSQC617 3HAC025338-001 / DSQC617 3HAC025338-004 to the controller wiring, connected axes, feedback interfaces and complete ordering record.
What energy must be isolated before servicing ABB DSQC617 3HAC025338-001 / DSQC617 3HAC025338-004?
Isolate mains and verify DC-link discharge before servicing ABB DSQC617 3HAC025338-001 / DSQC617 3HAC025338-004.
Why should DSQC617 connectors be labeled before removal?
Labeling prevents motor power, brake and feedback connections on ABB DSQC617 3HAC025338-001 / DSQC617 3HAC025338-004 from being returned to the wrong drive channel.
What should happen before ABB DSQC617 3HAC025338-004 is fully enabled?
Confirm the controller recognizes ABB DSQC617 3HAC025338-004, verify the drive configuration and test connected axes at controlled speed.
Does ABB DSQC617 3HAC025338-001 include the robot controller program?
No. ABB DSQC617 3HAC025338-001 is drive hardware; the robot application and controller configuration remain in the controller system.
