Honeywell Description of Parameters 157
385 AI1 sleep limit 6 (2.2.2.9)
The frequency drive is stopped automatically if the AI signal level falls below the Sleep
limit defined with this parameter. See Figure 8-35.

386 AI1 sleep delay 6 (2.2.2.10)
This parameter defines the time the analoque input signal has to stay under the sleep
limit determined with parameter ID385 in order to stop the frequency drive.
