ABB 4N10090 MU4003 Motor Unit – Axis Drive & Power Module | IRC5 Robot Platform
Engineering Background: The ABB IRC5 controller platform demands precision-matched drive components to maintain servo loop integrity across all six robot axes. The MU4003 Motor Unit (assembly references 3HAC040658-001 and 3HAC040657-001, catalog number 4N10090) is the factory-designated axis drive and power conditioning module for IRC5 single-cabinet and dual-cabinet configurations. It integrates rectification, DC bus management, and axis drive electronics into a single field-replaceable unit, minimizing downtime during maintenance cycles.
Product Positioning: Designed for procurement engineers and maintenance teams sourcing genuine ABB spare parts for IRB 1600, IRB 2400, IRB 4400, IRB 6600, and related IRC5-based robot families. Konmask.com supplies this unit with full traceability documentation, making it suitable for regulated manufacturing environments including automotive, electronics, and precision assembly.

Engineering Advantages
- OEM Genuine Part: Factory-matched to IRC5 servo loop parameters – no recalibration required post-swap.
- Dual Reference Numbers: 3HAC040658-001 (complete assembly) and 3HAC040657-001 (sub-assembly) ensure cross-compatibility across IRC5 revision levels.
- Integrated DC Bus Management: Eliminates external bus balancing components, reducing BOM complexity.
- Field-Replaceable Design: Hot-swap capable within IRC5 maintenance procedures; reduces MTTR vs. board-level repair.
- Traceability: Each unit supplied with serial number and batch documentation for ISO/TS 16949 and IEC 62443 compliance records.
System Architecture & Signal Flow
Within the IRC5 cabinet, the MU4003 Motor Unit sits between the main power supply (DSQC 604/661) and the individual axis drive boards. AC mains input is rectified to a shared DC bus; the MU4003 conditions and distributes this bus voltage to each axis drive card. Feedback signals from resolver/encoder circuits on the robot arm pass through the drive boards back to the main computer (DSQC 639) via the MU4003 backplane connectors. Replacing this unit restores full bus integrity without requiring axis-level reconfiguration.

Technical FAQ
Q: Is 3HAC040658-001 the same as 3HAC040657-001?
A: They are related assembly references within the same MU4003 unit family. 3HAC040658-001 refers to the complete motor unit assembly; 3HAC040657-001 is the sub-assembly reference. Both are fulfilled by the same physical unit (4N10090).
Q: Can this unit be used in IRC5 Compact controllers?
A: The MU4003 is designed for standard IRC5 single/dual cabinet configurations. Compatibility with IRC5 Compact should be verified against your specific cabinet BOM before ordering.
Q: Do you provide installation support?
A: Yes. Our engineering team can provide IRC5 maintenance procedure references and remote guidance. Contact support@konmask.com.
Q: What is the lead time for bulk orders?
A: Standard stock: 1–3 business days. For orders of 5+ units, contact us for dedicated stock reservation and volume pricing.
