3.5.3 Current Detection
3.5.3.1 Zero Current Detection
The DO outputs the active signal when the output current of the AC drive remains at
or below F8‑34 (zero current detection level) for a period greater than the value of F8‑
35 (zero current detection delay).

3.5.3.2 Output Current Limit Violation
The DO terminal outputs the active signal when the output current of the AC drive
remains above F8‑36 (output limit violation threshold) for a period greater than the
value of F8‑37 (output overcurrent detection delay).
