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

Product Condition	New original or used original. Please confirm the condition with us before ordering.
Shipping	Ships from Shanghai, China. Delivery lead time: 3-5 working days after order confirmation. Worldwide delivery by DHL / FedEx / UPS with secure packaging.
Buyer Benefits	ABB main servo drive unit for IRC5 drive modules, quoted against article 3HAC025338-004. The designation behind this article is the DSQC617 main drive configuration with the 3G and 3T power stages, as listed for IRC5 M2004 drive modules — we match on that identity, not on a photo. Suffixes in the 3HAC025338 series are not interchangeable: -003, -004 and -006 carry different drive stage configurations. Send us your old unit's article number and we confirm the match. One of the highest-consequence spares in a cabinet: when the main drive fails, the axes stop and the cell is down until it is replaced. We also quote the rectifier, capacitor unit and single drive units that sit alongside it, so a cabinet repair can be sourced in one go. Supplied as new original or used original; we confirm the condition with you before you order. Request a quote for current pricing and lead time — we do not publish stock levels or fixed dispatch promises. Shipped worldwide from Shanghai, China with protective packaging via DHL / FedEx / UPS.
Item Location	Ships from Shanghai, China.
Payment	PayPal / T/T / Alibaba Trade Assurance.

Description

Main Servo Drive Unit for ABB IRC5 Drive Modules

Specifications

Category	Main servo drive unit (drive module power stage)
Brand	ABB
Product Name	Main servo drive unit
Part Number	3HAC025338-004
Drive Designation	DSQC617, in the 3G3T configuration — the 3G and 3T power stages combined in one unit. ABB's IRC5 M2004 product manual lists this configuration for the main servo drive position, with drive unit nodes 1 to 6 allocated as T, G, T, G, T and G.
Definition	ABB 3HAC025338-004 is the main servo drive unit of an IRC5 drive module. In the ABB spare parts listing for the IRC5 M2004 controller it appears at the main drive position (A41.1), and the manual notes that the drive positions are covered by one single unit.
Function	Converts motion commands from the controller into drive power for the robot's axis motors, and closes the loop on encoder feedback for speed, torque and position control.
Series / Compatibility	ABB IRC5 drive modules, documented for the IRC5 M2004 generation. Compatibility depends on the cabinet type, the robot model and the drive stage configuration — send us your controller type, robot model and the article number on the original unit and we will confirm the match before supply.
Suffix Warning	Suffix variants in the 3HAC025338 series are not interchangeable. In the ABB M2004 listing the corresponding units are -003 (DSQC617 3E1C), -004 (DSQC617 3G3T) and -006 (DSQC617 3V3W). Order by the complete article number.
Predecessor / Service Article	The earlier article for this configuration is 3HAC14546-4, and service listings give E3HAC025338-004 as the exchange article. Confirm which one your system is built with and which part type you need.
Net Weight / Dimensions	Not confirmed. Published figures for this article disagree widely between sources, so we do not state a weight or a size.
Country of Origin	Not confirmed. Sources give different origins for this article.
Condition	New original or used original. Please confirm the condition with us before ordering.
Detailed Technical Parameters	ABB does not publish a full datasheet for this article in the data available to us, and reseller listings contradict one another on ratings, weight and origin. We do not repeat those figures. Send us your controller type and the original unit's article number and we will confirm the specification directly.

Industrial Applications

Replacing a failed main drive in an IRC5 drive module, where the cabinet is down until the unit is exchanged.
Automotive body shops, foundries and welding cells running IRC5-controlled robots on multi-shift production.
Metal processing, material handling, machine tending and general automation cells where an axis drive fault stops the line.
Planned spares for critical cells: a main drive is one of the parts most worth holding on the shelf.
Cabinet refurbishment and exchange programmes, where drives are swapped as a set with the rectifier and capacitor unit.

Design Purpose

Act as the power stage of the motion control system, turning control signals into motor current.
Regulate speed, torque and position for the robot axes using encoder feedback.
Carry the six main-axis drive nodes in one unit, as the ABB drive system configuration for this designation sets out.
Be exchangeable at the module level, so a cabinet can be brought back into production without rebuilding the drive system.

Safety & Installation Notice

Hazardous voltage. The drive system works on a high DC bus, and stored charge can remain after switch-off. Work inside the cabinet must be done by qualified personnel following ABB's procedure, with the controller isolated, locked out and the bus discharged before anything is touched.
Do not open the cabinet or handle the unit unless you are trained for work on industrial drive systems.
Confirm the drive stage configuration before ordering. -003, -004 and -006 in this series are different units, not alternatives to each other.
Match the article number and the designation on the original unit, not just its shape: IRC5 drive-system modules look similar but have different stage allocations.
Check the cooling path before fitting a replacement — a failed fan or blocked airflow will take out the new unit the same way it took out the old one.
Handle with electrostatic precautions and keep the unit in its packaging until it is fitted.
After replacement, follow ABB's start-up procedure for the drive system and check axis motion at reduced speed before returning the cell to production.
Send us the event log message from the controller with your enquiry; it tells us which stage has actually failed.

Common Failure Modes

Drive unit start-up error: the drive's internal logic does not initialise, so the controller will not bring the system to motors-on.
Over-temperature fault, from failed cooling fans, blocked airflow or aged components.
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, which the controller reports as a power fault.
Ordering the wrong suffix — fitting -006 where -004 is built, or the other way round.

Why Choose Us

Identity checked against ABB's IRC5 M2004 spare parts listing and the DSQC617 drive configuration, not against a reseller description.
Suffix check before we quote: -003, -004 and -006 are different drive configurations, and we confirm yours from the original unit.
We tell you what is not confirmed — weight, size and origin for this article are published inconsistently, so we do not pass those figures on as fact.
We can quote the rectifier, capacitor unit and single drive units from the same cabinet together with this 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.
