WebSep 24, 2024 · By executing and checking off steps as you take them, you can clearly identify which step (s) corrected the problem. Third, whenever possible let the VSD help you pinpoint the problem. Most drives have fault history tracing, which is extremely helpful in narrowing down the issue. This history is usually available via the VSD’s HMI; if the HMI ... In digital circuits, a high impedance (also known as hi-Z, tri-stated, or floating) output is not being driven to any defined logic level by the output circuit. The signal is neither driven to a logical high nor low level; this third condition leads to the description "tri-stated". Such a signal can be seen as an open circuit (or "floating" wire) because connecting it to a low impedance circuit will not affect that circuit; it will instead itself be pulled to the same voltage as the actively driven output. The co…
