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

1. Series Overview & Правила именования

The Siemens 1FK7 series (SIMOTICS S1FK7) are permanent magnet synchronous servo motors, divided into three types: Коннектикут (Компактный), 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.

5. Replacement Model Guide
6. Generation replacement: Gen1 5A series → Gen2 2A series (например, 1FK70815AZ91 → 1FK70812AZ91), mounting dimensions and electrical interfaces remain compatible
7. Обновление мощности: Same frame size, different length codes (например, 081 → 083, power from 12 кВт до 16 кВт)
8. Function upgrade: Standard → KUKA dedicated (requires 1ZZ9 mechanical interface and resolver)
9. Рекомендации по выбору
10. Power matching: Calculate required rated power and torque based on load; 20% margin recommended
11. Speed requirement: Confirm maximum speed meets application (стандартный 6000 об/мин, some up to 8000 об/мин)
12. Encoder selection: Absolute / incremental / resolver based on control system
13. Protection rating: Standard IP65, shaft IP67, подходит для суровых промышленных условий
14. Custom requirements: For KUKA robots and special applications, select dedicated models with 1ZZ9 suffix and Z code
