"Start/Stop" functions.
2. [Sleep-Wake Mode] must = "1, Direct" (Enable) or "2, Invert (Enable)."
3. [Sleep Level] must be less than [Wake Level] in Direct mode (or
greater than [Wake Level] in "Invert" mode).
4. [Speed Ref x Sel] must be set to a speed reference source that will
control the drive. If [Sleep-Wake Ref] = [Speed Ref x Sel], the same
analog signal will control start
/stop and speed reference.
5. At least one of the following must be programmed for [Dig Inx Sel]:
"Normal Stop," "Enable," "Start," "Run."
Is Analog Signal Greater
than or equal to [Wake Level]?
and for time period greater than
or equal to [Wake Time]
