FAT is the cheapest place to catch tuning drift
By the time the cabinet is on site, a current-loop mismatch becomes a schedule problem. FAT gives enough signal to fix it while the hardware team is still close to the project.
We keep one short log template for idle current, thermal state, and protection events so factory and field teams read the same evidence.
- Verify idle current after the final enclosure build, not before.
- Confirm protection thresholds with the intended PSU, not a bench supply.
- Save one reference log from the customer acceptance build.
FAT logging set
These checks are quick enough to repeat on every cabinet build.
| Signal | Target | Notes |
|---|---|---|
| Idle current | Expected hold state | Avoid unnecessary heating at dwell. |
| Current ripple | Within driver spec | No resonance burst in low-speed window. |
| Protection events | 0 unintended trips | Document every threshold that was changed. |
