FlexPendant units, DSQC drive and computer boards, power supplies, serial measurement boards and SMB batteries, axis motors, gearboxes and manipulator cabling — for S4C+, IRC5, IRC5 Compact and OmniCore. Tested on our own rigs and sold with a one-year warranty.
The components we are asked for most, what they do, which cabinet they belong to, and the fault that usually brings them to us. Use it to check you are ordering the right thing before you order it.
| Part number | Component | Controller generation | Typically replaced when |
|---|---|---|---|
| 3HAC028357-001 | DSQC679 FlexPendant teach pendant | IRC5 | Cracked screen, joystick drift, failed enabling device |
| 3HAC035301-001 | DSQC406 axis drive unit | IRC5 | Drive faults on a specific axis, DC-link errors |
| 3HAC042766-001 | DSQC1000 main computer unit | IRC5 (RW 5.6x / RW 6) | Controller will not boot, repeated system failures |
| DSQC609 | Power supply unit | IRC5 | Cabinet dead or unstable, 24 V rail collapsing under load |
| DSQC633 | Serial measurement board battery pack | IRC5 | Revolution counter lost after a power-down; annual-ish replacement |
| DSQC652 / DSQC651 | Digital and analog I/O units | IRC5 | I/O channels dead, comms alarms on the DeviceNet bus |
| 3HAC… motor units | Axis servo motors with brakes and encoders | S4C+ / IRC5 | Bearing noise, brake failure, encoder faults |
| 3HAC… harnesses | Manipulator-to-cabinet cable sets | S4C+ / IRC5 | Intermittent axis alarms that follow arm movement |
ABB parts carry two identifiers — an article number in the form 3HACxxxxxx-xxx and a DSQC designation. Both describe the same unit, and quoting either one is enough to start. Send us the number from your label and we will confirm the exact variant before quoting.
ABB labels the same component two different ways, which is why the same board turns up under two apparently unrelated numbers. Once you know which is which, identification gets much easier.
| Prefix / designation | What it identifies |
|---|---|
| 3HAC… | The article number — ABB's ordering reference, in the form 3HACxxxxxx-xxx. This is the number to quote |
| DSQC nnn | The unit designation printed on the board or label, e.g. DSQC679 for the IRC5 FlexPendant |
| 3HNE… / 3HNA… | Cables, harnesses and connection sets |
| SMB | Serial Measurement Board — reads axis encoders and holds the revolution counters |
| MU / MC | Measurement Unit and Main Computer, the two halves of the IRC5 control section |
| RW | RobotWare — the controller software version, which constrains which main computer will work |
1990s to mid 2000s, out of OEM support
Teach pendants and cables, drive units, main computer boards, power supplies, SMB units and batteries, axis motors and harnesses. Board repair and refurbished stock are the realistic routes.
The volume generation in service today
DSQC679 FlexPendant (3HAC028357-001), DSQC406 drive units (3HAC035301-001), DSQC1000 main computers (3HAC042766-001), DSQC609 power supplies, SMB boards and DSQC633 battery packs, DSQC651/652 I/O units, contactor and safety modules.
Current generation
Pendants, drive and computer modules, power and safety hardware. Sourcing and priority dispatch rather than obsolescence work.
Most wrong-part orders come from reading the robot model off the arm and stopping there. The controller generation matters as much as the robot.
We supply parts and we repair them, so we have no reason to push you either way. When a repair is the better answer for your situation, we say so.
| Condition | What it means | Testing | Warranty |
|---|---|---|---|
| New | Unused stock, original packaging where supplied that way | Function-checked before dispatch | 1 year from purchase |
| Refurbished | Stripped, worn components replaced, rebuilt to working spec | Full run on our test rig | 1 year from purchase |
| Tested used | Working pulled unit, cleaned and verified | Full run on our test rig | 1 year from purchase |
| Repaired (your unit) | Your own component, fault repaired at board level | Validated on the rig before return | 6 months from repair |

Diagnosed before it is quoted, six-month warranty.
Catch the wear part before it stops the line.
Hands-on, on live ABB equipment.
Brand, model, controller generation and a photo of the label is enough to get a firm price and a real lead time.
S4C and S4C+, IRC5 and IRC5 Compact, and OmniCore. S4C+ generation cells are regular work for us because they are still productive and no longer supported by ABB.
The IRC5 FlexPendant is the DSQC679, ordered as article number 3HAC028357-001. Both identifiers describe the same unit — quoting either is enough for us to start, though the number on your own label is always safest.
The 3HACxxxxxx-xxx article number is ABB's ordering reference. The DSQC designation is the unit name printed on the board or its label. The DSQC679 FlexPendant and article 3HAC028357-001 are the same thing described two ways, which is why the same board appears under two apparently unrelated numbers.
Yes — screens, joysticks, enabling devices, membranes, housings and cables are repairable at component level, validated on a rig and returned with a six-month warranty. Joystick drift and a failed enabling device are both routine repairs and rarely justify a new pendant.
Almost always the serial measurement board battery pack, commonly the DSQC633. It is a wear item on roughly an annual cycle. Replace the pack, then update the revolution counters — the robot does not need a full re-calibration for this on its own.
Yes — axis servo motor units with brakes and encoders, gearboxes and wrist units, and the manipulator-to-cabinet cable harnesses. Motors are run under load on a test rig before dispatch.
RobotWare version constrains the choice: the DSQC1000 main computer is specified for IRC5 with RobotWare 5.6x and RobotWare 6. Tell us the RobotWare version alongside the article number and we will confirm the match before quoting rather than after.
Yes, anywhere in India from our Pune facility, and into Europe through our branch in Germany.
