This function will put the drive into sleep mode if the frequency stays below the
sleep limit for a longer time than that set with the Sleep Delay (P15.12). This

When the actual value goes below, or above, the wake-up error depending on
the set acting mode the drive will activate the run request again if the start
command is still on.
