Industrial Robot Drive Solution – ABB MU200 / MU400 Motor Unit | IRC5 Series
The ABB MU200 (3HAC040656-001) and MU400 (3HAC040658-001 / 3HAC040658-002) are dedicated motor units designed for ABB IRC5 modular controller systems. These units deliver precise servo drive power to ABB IRB robot axes, making them essential components in high-throughput industrial automation environments. Konmask.com supplies genuine and equivalent-grade motor units with full traceability for global B2B buyers.
Where This Product Is Used
These motor units are deployed across a wide range of demanding industrial applications:
- Automotive Body-in-White (BIW): Spot welding and seam welding lines using ABB IRB 6600 / IRB 6700 robots require MU400 units to sustain high-cycle torque demands on axes 1–3.
- Palletizing & Material Handling: High-payload robots (IRB 660, IRB 760) in FMCG and logistics centers rely on MU400 for continuous-duty axis drives.
- Arc Welding Cells: IRB 1600 / IRB 2600 installations use MU200 units for axes 4–6, where compact form factor and low inertia are critical.
- Machine Tending & Press Tending: CNC machine tending lines with IRB 4600 robots use both MU200 and MU400 depending on axis assignment.
- Electronics Assembly: Clean-room IRB 120 / IRB 1200 cells use MU200 for precise, low-noise servo control.
- Food & Beverage Processing: Washdown-rated robot cells with IRC5 controllers require motor units with stable thermal performance across shift cycles.

Why Engineers Specify This Model
- Plug-and-Play IRC5 Integration: Motor units slot directly into the IRC5 modular drive bay — no re-parameterization required when replacing like-for-like.
- Axis-Matched Power Rating: MU200 and MU400 are factory-matched to specific robot axes, ensuring optimal current loop tuning and thermal headroom.
- Reduced Downtime Risk: Stocking both MU200 and MU400 covers the full axis complement of most ABB IRB robot families, minimizing unplanned line stops.
- Firmware Compatibility: Compatible with RobotWare 5.x and 6.x; no drive firmware flashing required for standard replacement.
- Long Service Life: Designed for 24/7 industrial duty cycles with built-in thermal protection and overcurrent shutdown.

Application-Specific FAQ
Q: Can the MU200 replace the MU400 in an emergency?
A: No. The MU200 and MU400 have different power ratings and connector pinouts. Substituting them will cause axis faults or drive damage. Always match the motor unit to the axis specification in the IRC5 cabinet label.
Q: How do I identify which motor unit my IRC5 cabinet needs?
A: Open the IRC5 cabinet door and locate the drive module bay. Each slot is labeled with the required part number on the cabinet wiring diagram (typically affixed inside the door). Cross-reference with the robot’s product manual axis drive table.
Q: Are 3HAC040658-001 and 3HAC040658-002 interchangeable?
A: In most IRC5 installations, -001 and -002 revisions of the MU400 are functionally interchangeable. Confirm with your ABB service documentation or contact Konmask.com for revision-specific guidance.
Q: What is the lead time for MU200 and MU400 units?
A: In-stock units ship within 3–5 business days. For bulk or project orders, lead times are confirmed at quotation stage.
Q: Do you provide installation support?
A: Konmask.com provides part-level technical documentation. For on-site commissioning, we recommend engaging a certified ABB service partner.
