- Foundry and die-casting automation
- Machine tending and press-tending cells
- Palletizing and depalletizing systems
- Aerospace component machining support
System Compatibility
- Robot: ABB IRB 7600 (all variants: 150/2.55, 325/3.1, 340/2.8, 400/2.55, 500/2.55)
- Controller: ABB IRC5 (single cabinet and dual cabinet)
- Drive Module: ABB DSQC series axis drive boards
- Software: RobotWare 5.x / 6.x compatible
Selection Guide
Use the checklist below to select the correct suffix variant:
- ✅ Step 1 – Identify the axis: Check the robot arm label or ABB documentation to confirm which axis motor requires replacement (Axis 1, 2, or 3).
- ✅ Step 2 – Match the suffix: -001 = Axis 1 | -002 = Axis 2 | -003 = Axis 3.
- ✅ Step 3 – Verify IRB 7600 variant: Confirm payload and reach model (e.g., 500/2.55) to ensure torque rating alignment.
- ✅ Step 4 – Check encoder type: Resolver vs. encoder feedback — confirm with your IRC5 drive module specification.
- ✅ Step 5 – Contact Konmask: Send your robot serial number for cross-verification before purchase.
