ABB 3HAC025338-004/3HAC025338-006 Main Servo Drive Unit – IRC5 Robot Controller Series
When a Main Servo Drive Unit fails inside an ABB IRC5 robot controller, the entire production line comes to a standstill. The servo drive is the power heart of the robot — without it, no axis moves, no weld is made, no part is assembled. Every minute of unplanned downtime in an automotive body shop or electronics assembly plant can cost thousands of dollars. The ABB 3HAC025338-004 / 3HAC025338-006 is the exact OEM-specified replacement that restores full robot operation without reconfiguration or software changes.
The 3HAC025338-004 and its revision 3HAC025338-006 are the primary Main Servo Drive modules used across the ABB IRC5 single-cabinet and dual-cabinet controller platforms — one of the most widely deployed industrial robot controller families in the world. These part numbers cover the core drive board responsible for coordinating multi-axis servo power delivery, making them critical spare parts for any facility running ABB IRB 1600, IRB 2400, IRB 4600, IRB 6640, or related robot models. Their global installed base spans automotive, foundry, food & beverage, and general manufacturing sectors.

Frequently Asked Questions
Q: What is the difference between 3HAC025338-004 and 3HAC025338-006?
A: These are sequential hardware revision codes for the same Main Servo Drive Unit. The -006 revision incorporates minor component updates from ABB but is functionally interchangeable with -004 in most IRC5 cabinet configurations. Always confirm with your ABB service documentation or contact us for verification.
Q: Which ABB robot models use this servo drive?
A: This unit is used in ABB IRC5 controller-based robots including the IRB 1600, IRB 2400, IRB 4600, IRB 6640, and other models in the IRC5 platform family. Compatibility depends on your specific cabinet variant.
Q: Do you supply new or refurbished units?
A: We can supply both new OEM units and professionally refurbished/tested units depending on availability and your budget requirements. Please specify your preference in your inquiry.
Q: How long does shipping take?
A: Lead time and shipping duration depend on stock availability and destination country. We provide estimated delivery timelines in the formal quotation. Express shipping options are available.
Q: Can you provide a warranty?
A: Yes. Warranty terms vary by unit condition (new vs. refurbished). Details are included in the quotation. Contact us for specifics.
