RFQ Preparation Checklist
- Axis payload and arm inertia assumptions
- Cycle-time and acceleration profile
- Repeatability target and backlash budget
- Motor model and controller family
Selection and validation guidance for SCARA robot axes requiring high repeatability and controlled backlash.
| Evaluation Metric | Typical Range | Buyer Relevance |
|---|---|---|
| Repeatability Target | ±0.02 to ±0.10 mm | Gearhead characteristics directly influence repeatability performance. |
| Inertia Ratio | Recommended <= 5:1 | Improves tuning robustness and reduces oscillation risk. |
Yes. Early-stage motor and ratio review is supported to reduce redesign loops.
Use these references to turn scenario assumptions into measurable motor-gearhead selection criteria.
Build first-pass ratio boundaries from inertia and torque before vendor comparison.
Pick frame size by actual duty profile, torque reserve, and thermal margin.
Translate technical reliability assumptions into procurement decisions with fewer ramp surprises.
