- Key Selection Guidelines for Replacement
- Spannungsanpassung
Original motor: 380~480V → prefer Mitsubishi 400V class (HK-KT7M4UW, HG-SN702BJ)
For 200V models (HG-KN73BJ), a 380→200V transformer is required.
- Dynamic Performance Matching
1FK2 is high dynamic & low inertia → prefer Mitsubishi low-inertia series (HK-KT/HK-KP/HG-KN)
Medium-inertia series (HG-SN) for higher load inertia applications.
- Encoder & Control
Original: absolute encoder → select Mitsubishi absolute type (suffix “J” or “UW”)
MR-J5 supports battery-free absolute position retention.
- Mechanical Compatibility
90mm standard flange: fully interchangeable
Check shaft diameter (φ12mm) and keyway; use adapter coupling if needed.
- Recommended Drives
| Mitsubishi Motor Series | Recommended Drive |
| MR-J5 Series | MR-J5-700A (400V, 0.75kW) |
| MR-J4 Series | MR-J4-70A (400V, 0.75kW) |
| MR-JE Series | MR-JE-70A/B (200V, 0.75kW) |
- Final Selection Recommendations
- New projects / full upgrade: Choose HK-KT7M4UW (MR-J5) – latest tech, superior performance, supports Industry 4.0 & EtherCAT.
- Existing system retrofit: Choose HG-SN702BJ-S100 (MR-J4) – stable, compatible, kostengünstig.
- Budget-sensitive applications: Choose HG-KN73BJ-S100 (MR-JE) – high cost-performance for general use.

- Brand Features Summary
- Mitsubishi (MR-J5 / HK-KT7M4UW)
Closest to 1FK2 in performance, size, dynamics; battery-free absolute; top choice for new projects.
- Yaskawa (Σ-7 / SGM7A-07A7A61)
Low-inertia, high stability; preferred for heavy-duty and retrofit applications.
- Schneider (BSH0702P11A2A)
European standard; excellent mechanical & communication compatibility for European equipment.
- Panasonic (A6B)
Kostengünstig, compact; ideal for small-to-medium machines and volume applications.
- ABB / Omron
High precision & Zuverlässigkeit; suitable for high-end equipment and factory automation.
III. Mandatory Replacement Rules (Must Read)
- Voltage must match: Original = 400V → use 400V models only; do NOT use 200V motors directly.
- Torque first: Rated torque ≥ 2.4Nm; prefer low inertia for dynamics.
- Encoder consistency: Use multi-turn absolute encoders to avoid position loss.
- Mounting compatibility: All use 90mm flange, φ12mm shaft – direct drop-in replacement.
