ABB identifies DSQC664 under article number 3HAC030923-001 as a ADU-790A additional drive unit. The documented hardware belongs to the IRC5 drive system configuration and must be selected by the complete DSQC designation together with the ABB article number. Its interfaces, software or axis assignment depend on the installed controller and option set. Buyers should therefore compare the nameplate, controller generation and applicable ABB manual before replacement rather than relying on enclosure appearance or the short DSQC code alone.
Before replacing DSQC664, record the installed position, hardware revision, mounting or connector arrangement, paired assemblies and every applicable ABB service record. Compare the supplied unit with the original item and approved configuration, isolate all relevant energy sources, and follow the documented installation procedure. After installation, inspect every affected mechanical, electrical and communication interface and complete controlled functional checks before returning the equipment to service.
The DSQC664 ABB High-voltage additional drive unit is listed as Active / Available from OEM. Current revision, availability and supplied scope are confirmed in the written quotation.
ABB DSQC664 documentation and reference links.
Important Notice: Every linked document must identify the listed model or its documented family. Confirm the complete order code, hardware revision and installed-system requirements before replacement.
Order verification starts with both DSQC664 and 3HAC030923-001. The controller family, installed position, connectors and visible revision information should be compared with the actual unit before replacement.
The module must be checked against the documented IRC5 drive system hardware and software arrangement. Similar DSQC enclosures or neighboring article numbers are not sufficient evidence of interchangeability.
Before replacement, preserve controller records, document wiring or mechanical connections and follow the applicable ABB isolation, ESD and recommissioning procedures. Required accessories are confirmed separately for the actual service scope.
