Series: MD200

Excessive speed deviation fault

AC drive

Meaning: The AC drive reports an excessive speed deviation fault when it detects that the deviation between the actual motor speed and the frequency setting exceeds F9-69 (excessive speed deviation detection value) for longer than F9-70 (excessive speed deviation detection time).

Series: MD310

Excessive speed deviation fault

AC drive

Meaning: For excessive speed deviation protection, if the AC drive detects a deviation between the actual motor speed and the set frequency that exceeds F9-69 × maximum frequency F0-10 (Excessive speed deviation detection value) and persists longer than F9-70 (Excessive speed deviation detection time), the AC drive reports an excessive speed deviation fault (Err42) and responds according to F9-52 (Fault protection action mode). When F9-70 (Excessive speed deviation detection time) is set to 0.0s, excessive speed deviation fault detection is disabled. The excessive speed deviation protection function is valid only when the AC drive operates in SVC mode (F0-01=1).
