Application Notes Appendix C
Definitions
• Wake - A start command generated when the analog input value remains
above [Wake Level] (or below when Invert mode is active) for a time
greater than [Wake Time].
• Sleep - A Stop command generated when the analog input value remains
below [Sleep Level] (or above when Invert mode is active) for a time
greater than [Sleep Time].
• Speed Reference – The active speed command to the drive as selected by
drive logic and [Speed Ref x Sel].
• Start Command - A command generated by pressing the Start button on
the HIM, closing a digital input programmed for Start, Run, Run Forward
or Run Reverse.
Refer to Figure 22 .

Which Mode is Selected?
"Invert" or "Direct"
1. [Sleep-Wake Ref] must be set to the analog input that will control
"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 [Digital Inx Sel]:
"Not Stop," "Enable," "Start," "Run," "Run Forward," "Run Reverse."
Is Analog Signal Greater
than or equal to [Wake Level]?
and for time period greater than
or equal to [Wake Time]
Yes Yes
Is Analog Signal Less
than or equal to [Wake Level]?
and for time period greater than
or equal to [Wake Time]
Increase Analog Input
Signal and wait for a time
period greater than or
equal to [Wake Time].
Decrease Analog Input
Signal and wait for a time
period greater than or
equal to [Wake Time].
Was a Stop Issued?
or Power Cycled?
