ABB DSQC617 3HAC14546-1 / DSQC617 3HAC14546-2 Main servo drive unit variants
Main servo drive units for the ABB robot controller drive system, identified by the complete ABB model and ordering record.
01
Product Details
ABB DSQC617 3HAC14546-1 / DSQC617 3HAC14546-2 identifies two main servo drive unit records for ABB robot-controller drive hardware. The two ordering numbers distinguish the motor-channel arrangement associated with each installed unit.
Within the controller, ABB DSQC617 3HAC14546-1 / DSQC617 3HAC14546-2 receives the controller drive commands and supplies the connected robot motors through the installed power and feedback interfaces. The complete designation is therefore matched to the robot drive configuration rather than selected by cabinet appearance.
Before either ABB DSQC617 3HAC14546-1 / DSQC617 3HAC14546-2 is removed, mains and DC-link energy are isolated and the drive connectors are labeled. After replacement, the controller drive configuration, connected axes and fault-free enable sequence are checked at controlled speed.

03
Operating Characteristics
The two DSQC617 ordering records perform the same controller-level drive role but organize the connected motor channels differently.
Ordering-specific channels
The ordering number identifies the installed drive-channel arrangement and must remain attached to the service record.
Drive-state supervision
The controller monitors drive readiness and faults before the motors can be enabled.
04
Diagnostics and Protection
Separate the unit from surrounding faults
Drive troubleshooting uses the complete ordering record, connector record and controller fault sequence rather than replacing a unit on one alarm alone.
Isolate the energy path
Remove mains and verify the DC link is discharged before drive connectors are handled.
Preserve connector identity
Label motor, feedback and supply connections so the exact channel arrangement is restored.
Commission at controlled speed
Clear faults only after configuration and wiring checks, then verify each affected axis before automatic production.

Product Q&A
How do ABB DSQC617 3HAC14546-1 and DSQC617 3HAC14546-2 differ?
They are main servo drive unit records for different installed drive-channel arrangements.
Can ABB DSQC617 3HAC14546-1 / DSQC617 3HAC14546-2 be chosen by appearance?
No. Match the complete ordering number to the installed drive configuration.
What energy remains after power is removed from ABB DSQC617 3HAC14546-1 / DSQC617 3HAC14546-2?
Treat the DC link as stored electrical energy and verify discharge before touching drive connections.
Why should every connector be labeled for ABB DSQC617 3HAC14546-1 / DSQC617 3HAC14546-2?
The motor and feedback paths must return to the same drive channels.
What is checked after installing ABB DSQC617 3HAC14546-1 / DSQC617 3HAC14546-2?
Check the drive configuration, fault state, affected axes and controlled-speed motion.
Does the DSQC617 family name fully identify ABB DSQC617 3HAC14546-1 / DSQC617 3HAC14546-2?
No. Retain the complete 3HAC ordering number.
