11.11.6.2 (ID 700) Analog Input Low Fault
Location in the menu: P3.9.8.2
Use this parameter to select the response of the drive to an 'AI Low' fault. If the analog input signal becomes less than 50% of the
minimum signal for 500 ms, an AI Low fault occurs.
If AI Low Protection is enabled with parameter P3.9.8.1, this parameter gives a response for the fault code 50 (Fault ID 1050).
The AI low protection function monitors the signal level of the analog inputs 1–6. If the analog input signal becomes less than 50%
of the minimum signal for 500 ms, an AI Low fault, or alarm shows.
It is possible to use the value Alarm + previous frequency only when using analog input 1 or analog input 2 as frequency refer-
ence.
