Complete Model Guide for Siemens 1FK7 Series Compact Synchronous Servo Motors

1. Series Overview & Naming Rules

The Siemens 1FK7 series (SIMOTICS S1FK7) are permanent magnet synchronous servo motors, divided into three types: CT (Compact), HD (High Dynamic), HI (High Inertia).

The following focuses on the full CT Compact models (selfcooled IC410, IMB5 mounting), available in Generation 1 (5A series) and Generation 2 (2A series), with Generation 2 as the current mainstream.

Model Naming Convention (1FK7xxxxxxxxxxxxxxZ)

2. Complete Model List (by Frame Size / Shaft Height)
3. 20 mm Shaft Height (01 Series, 0.18–0.35 kW)

2. 30 mm Shaft Height (02 Series, 0.38–0.85 kW)

3. 40 mm Shaft Height (03/04 Series, 1.15–3 kW)

4. 60 mm Shaft Height (06 Series, 3–11 kW)

5. 80 mm Shaft Height (08 Series, 8–20 kW)

6. 100 mm Shaft Height (10 Series, 18–48 kW)

3. Special Custom Models (For KUKA Robots)

4. Encoder & Cooling Options
5. Encoder Types

มาตรฐาน: DRIVECLiQ absolute encoder (20bit singleturn / 12bit multiturn)

KUKA dedicated: Resolver

ไม่จำเป็น: Incremental encoder (2048 lines)

2. Cooling Methods

มาตรฐาน: Selfcooled IC410 (IP65 protection)

ไม่จำเป็น: Forcedair cooled IC416 (for continuous highload operation)

5. Replacement Model Guide
6. Generation replacement: Gen1 5A series → Gen2 2A series (เช่น, 1FK70815AZ91 → 1FK70812AZ91), mounting dimensions and electrical interfaces remain compatible
7. Power upgrade: Same frame size, different length codes (เช่น, 081 → 083, power from 12 kW to 16 กิโลวัตต์)
8. Function upgrade: Standard → KUKA dedicated (requires 1ZZ9 mechanical interface and resolver)
9. Selection Guidelines
10. Power matching: Calculate required rated power and torque based on load; 20% margin recommended
11. Speed requirement: Confirm maximum speed meets application (มาตรฐาน 6000 รอบต่อนาที, some up to 8000 รอบต่อนาที)
12. Encoder selection: Absolute / incremental / resolver based on control system
13. Protection rating: Standard IP65, shaft IP67, suitable for harsh industrial environments
14. Custom requirements: For KUKA robots and special applications, select dedicated models with 1ZZ9 suffix and Z code
