ABB 3HAC025338-004 Main Servo Drive Unit for IRC5 M2004

ABB 3HAC025338-004 Main Servo Drive Unit for IRC5 M2004

3HAC025338-004 is the ABB main servo drive unit for the IRC5 drive system, catalogued as Main Servo Drive Unit, D6 3T 3G with hardware designation DSQC 617_3G3T. It carries the main-axis power stages of the drive module as one single unit, so it is matched by configuration rather than by outline: the drive unit nodes are allocated T, G, T, G, T and G across nodes 1 to 6. ABB's IRC5 documentation lists this configuration for IRB 4400 and IRB 6400RF drive modules, and the earlier article for the same configuration is 3HAC14546-4. Send us the article number on your original unit, the robot model and the controller type, and we confirm the match before you order.

Specifications

Weight, packing dimensions, customs classification and country of origin are confirmed against the unit we quote, so the figures on your quotation match the article number and revision you receive.

Industrial Applications

• Replacing a failed main drive in an IRC5 drive module, where the cell stays down until the unit is exchanged.
• Automotive body shops, foundries and welding cells running IRB 4400 or IRB 6400RF robots on multi-shift production.
• Metal processing, material handling, machine tending and general automation cells where a main drive fault stops every axis.
• Planned spares for critical cells: the main drive is one of the highest-consequence parts to hold on the shelf.
• Cabinet refurbishment and drive-system exchange programmes, where drives are swapped as a set with the rectifier, capacitor unit and single drive units.

Design Purpose

• Act as the power stage of the motion control system, converting controller commands into drive current for the robot's axis motors.
• Regulate speed, torque and position from encoder feedback, so axis motion follows the programmed path.
• Carry the main-axis drive nodes in one unit, so a single module covers the whole main-axis position set instead of several separate units.
• Be exchangeable at module level, so a cabinet returns to production without the drive system being rebuilt.

Common Failure Modes

• Drive unit start-up error – the internal logic does not initialise and the controller will not bring the system to motors-on.
• Drive unit temperature warning, from failed cabinet fans, blocked airflow or aged components. Troubleshooting:ABB IRC5 drive unit alarm guide
• Overcurrent or short-circuit shutdown in the power stage, which stops the affected axes.
• Axis not responding – the controller powers up but one or more axes will not move.
• Communication loss between the controller and the drive unit.
• Missing or failed incoming mains or bleeder circuit, reported by the controller as a power fault.
• Wrong suffix fitted – the suffixes in this series carry different stage allocations and are not interchangeable.

Why Choose Us

• Identity checked against ABB's IRC5 drive system configuration and the DSQC 617_3G3T stage allocation, not against a reseller description.
• Suffix and revision confirmed before we quote, so the unit you receive matches the configuration in your cabinet.
• We can quote the capacitor unit, rectifier and single drive units from the same drive module together with this main drive.
• New original or used original; we confirm the condition with you before you order.
• Carefully packed and shipped worldwide from Shanghai, China via DHL / FedEx / UPS.
