Compatible Replacement & Equivalent Models
The following parts are verified compatible or functionally equivalent to the ABB 3HAC050270-001. Always confirm firmware revision and mechanical interface before substitution:
- 3HAC050270-002 — Revised production batch; direct drop-in replacement for -001 revision
- 3HAC026253-001 — Earlier axis unit used in IRB7600 pre-2014 builds; verify axis number and mounting bracket
- 3HAC14550-2 — Compatible axis motor for select IRB7600-325/3.1 configurations
- DSQC662 / 3HAC026254-001 — Drive module pairing; often replaced alongside axis unit during full drive-chain overhaul
Note: Cross-reference by robot serial number and axis position (Axis 1–6) before ordering. Contact support@konmask.com for free compatibility verification.
Why Choose the Original Model
- OEM Precision: Factory-calibrated torque and encoder parameters — no re-tuning required after swap
- Warranty Integrity: Maintains ABB robot warranty and IRC5 controller compatibility
- Longevity: ABB-grade materials rated for high-cycle industrial environments (automotive, foundry, heavy assembly)
- Traceability: Full ABB part traceability and CE/UL compliance documentation available
Typical Applications
- Automotive body welding and spot-welding lines (IRB7600-500/2.55, IRB7600-340/2.8)
- Heavy material handling and press-tending automation
- Foundry and die-casting robot cells
- Palletizing and depalletizing systems (>500 kg payload lines)
- Axis drive replacement during scheduled preventive maintenance (PM) cycles
System Compatibility
- Robot: ABB IRB7600 series — all payload/reach variants (150/3.5, 325/3.1, 340/2.8, 400/2.55, 500/2.55, 600/2.55)
- Controller: ABB IRC5 (M2004 and later); IRC5 Compact with Drive Module
- Software: RobotWare 5.x / 6.x — axis calibration via FlexPendant after replacement
- Drive Module: DSQC662 / DSQC663 axis drive boards
Selection Guide
Use the checklist below to confirm the correct part before purchase:
- Identify axis number — Axis 1 (base rotation) through Axis 6 (wrist) have different mechanical interfaces; confirm axis position from robot nameplate or ABB spare parts catalog.
- Check robot serial number — IRB7600 units manufactured before 2013 may use earlier revision axis units. Provide serial number to Konmask for cross-check.
- Verify revision suffix — -001 and -002 are interchangeable in most cases; -003 and later may require firmware update on IRC5 controller.
- Assess condition requirement — New OEM for critical production lines; certified refurbished for backup/spare inventory; exchange program available to reduce cost.
- Confirm lead time tolerance — New OEM: 2–8 weeks; Konmask stock (new/refurb): typically ships within 3–5 business days.

Replacement & Compatibility FAQ
Q: Can 3HAC050270-002 replace 3HAC050270-001 directly?
A: Yes. The -002 suffix denotes a revised production batch with identical form, fit, and function. No parameter changes are required on the IRC5 controller.
Q: Do I need to recalibrate the robot after replacing the axis unit?
A: Yes. ABB recommends running the axis calibration routine via FlexPendant (Calibration > Update Revolution Counter) after any axis drive replacement.
Q: Is this part compatible with IRC5 Compact controllers?
A: Yes, provided the drive module (DSQC662/663) is also compatible. Contact us with your controller serial number to confirm.
Q: What is the lead time for a new OEM unit?
A: Typically 2–8 weeks from ABB. Konmask maintains refurbished and exchange stock that ships within 3–5 business days.
Q: Do you offer an exchange/core program?
A: Yes. Send your defective unit and receive a tested replacement at reduced cost. Contact us for exchange terms.
