Application Notes Appendix B
Sleep-Wake Mode
This function stops (sleep) and starts (wake) the drive based on separately
configured analog input levels rather than discrete start and stop signals. When
enabled in “Direct” mode, the drive will start (wake) when an analog signal is
greater than or equal to the user specified [Wake Level], and stop the drive when
an analog signal is less than or equal to the user specified [Sleep Level]. When
Sleep-Wake mode is enabled for “Invert” mode, the drive will start (wake) when
an analog signal is less than or equal to the user-specified [Wake Level], and stop
the drive when an analog signal is greater than or equal to the user-specified
[Sleep Level]. See Figure 9
on page 172 for more information on Sleep-Wake
mode configuration.
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.
