- Critical Implementation Notes (Muss gelesen werden)
- Mechanical Matching
Wellentyp: Must be involute spline shaft (KUKA standard); keyed shafts require adapters.
Montagemaße: Match 1FK7081 flange and hole pattern; 3D comparison recommended.
Moment of inertia: Tolerance ≤15% vs original (24 kg·cm²) to avoid performance issues.
- Electrical Matching
| Electrical Item | Matching-Anforderung | Risiko einer Nichtübereinstimmung |
| Encoder protocol | Must support EnDat 2.2 (KUKA compatible) | No position feedback; requires converter |
| Motor winding | Suitable for 560V DC bus voltage | Motor/drive burnout |
| Feedback connector | Match KUKA standard (25‑pin) | Custom cable needed, higher failure risk |
| Brake system | Holding torque ≥11Nm, DC 24V | Cannot hold position when powered off |
- Software Configuration
- Update motor parameters in KUKA controller (torque constant, inertia, encoder type, usw.)
- Recalibrate robot zero and dynamic parameters
- Perform load identification and trajectory optimization
- Test full travel and overload performance to validate replacement
- Siemens Original Replacements (Best Compatibility)
- Series Upgrade Options
| Siemens Model | Schlüsselparameter | Anwendungshinweise | KUKA Spare Part No. |
| 1FK7081-2AC71-1UA0 | 3.7KW, 12Nm, 3000U/min | Standardersatz; parameter adjustment required | No direct match, custom only |

- Replacement Priority
- Genuine KUKA spare part (00-115-925): Best compatibility, for critical equipment
- Yaskawa/Mitsubishi KUKA custom versions: Near-original, no modification, moderate cost
- Other brand custom versions: Cost advantage, requires professional support
- Standard model modification: Niedrigste Kosten, full mechanical/electrical/software changes, high risk
- Implementation Steps (For Success)
- Parameter verification: Confirm all original motor specs and create a matching sheet
- Model selection: Choose brand/model based on budget and application
- Sample testing: Install and test 1 unit to verify mechanical/electrical/software compatibility
- Batch replacement: Implement one by one after validation
- Documentation update: Record replacement model and parameters in equipment files
1FK7081-5AZ91-1ZZ9-Z is a KUKA custom motor. Always use KUKA-approved replacements to avoid performance loss or safety hazards. Full functional and safety testing is strongly recommended after replacement.
