"Start/Stop" functions.
2. [Sleep-Wake Mode] must = "1, Direct" (Enable).
3. [Sleep Level] must be less than [Wake Level].
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 [Digital Inx Sel]:
"Not Stop," "Enable," "Start," "Run," "Run Forward," "Run Reverse."
