The 3HAC025338-001 is d6 3b 3a main servo drive unit used in ABB IRC5 M2004 robot controllers. It provides the integrated 3B and 3A main-axis drive stages for the documented controller configuration.
Confirm the IRC5 controller, robot model, stage allocation and original 3HAC14546-1 hardware. The full 3HAC025338-001 article number and the installed controller nameplate should be compared before a purchase order is released.
Follow the ABB controller service instructions and verify DC-link discharge, module location, busbar connections, cooling and motor-stage wiring. Any cable, busbar, harness, fan lead, or mounting hardware must be identified separately unless included in the quotation.
DSQC617_3B3A, identified as one main drive unit in ABB IRC5 spare-parts documentation. Use the ABB article number and DSQC/type designation together when reviewing a replacement.
Engineering check: Confirm 3HAC025338-001 replaces 3HAC14546-1 and is the DSQC617 D6 3B 3A main drive. Verify the 3B/3A stage assignment, connector keying and IRC5 M2004 cabinet configuration before installation.
Acceptance test: After the DC link has been safely discharged, connect the assigned motor, brake and feedback harnesses. Energize under service control, jog each stage at reduced speed and verify current, feedback direction, following error and drive diagnostics.
