Dead band (P3.12.1.9)
Dead band delay (P3.12.1.10)
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.
