# Industrial Specification: Feedback Interface

## 1. Technical Definition
Electronic interface that receives and processes position and motion data from sensors in a 5-axis CNC system

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-5 VDC analog signal input, 0.1-10 kHz sampling frequency, -40°C to 85°C ambient temperature**. Failure boundary: **Signal voltage exceeding 5.5 VDC causes ADC saturation, sampling frequency below 0.1 kHz creates aliasing, temperature beyond 85°C triggers thermal shutdown at 125°C junction temperature**, Mechanism: **Semiconductor junction breakdown at 5.5 VDC reverse bias voltage, Nyquist-Shannon sampling theorem violation below 0.1 kHz, silicon bandgap thermal runaway beyond 125°C junction temperature**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
