Figure 25: Dead band.
Sleep frequency limit 1 (P3.12.2.7), Sleep delay 1 (P3.12.2.8), and Wake-up level 1
(P3.12.2.9)
This function puts the drive into sleep mode if the frequency stays below the sleep limit for a longer period
than that set with the Sleep Delay (P3.12.2.8). This means that the start command remains on, but the run
request is turned off. When the actual value goes below or above the wake-up level depending on the set
acting mode, the drive will activate the run request again, if the start command is still on.
