Most Common Faults We Can Solve

- OverSpeed Limit: Speed correction exceeded [Overspeed Limit].
Fix: Remove overhauling load or raise limit; we re-tune slip/bus regulation.
- Encoder Loss: One encoder channel missing (requires differential).
Fix: Verify wiring, rotation, pulse rate; we replace encoder/cable and re-align.
