Rockwell Automation 20M LPM15 Liquid-Cooled Adjustable Frequency AC Drive FRN 2.xxx - Manual (Page 120)

D-10 Application Notes
Sleep Wake Mode This function stops (sleep) and starts (wake) the drive based on separately
configurable 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].
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].
If skip bands overlap or touch, the
center frequency is recalculated
based on the highest and lowest
band values.
If a skip band(s) extend beyond the
max frequency limits, the highest
band value will be clamped at the
max frequency limit. The center
frequency is recalculated based on
the highest and lowest band
values.
If the band is outside the limits, the
skip band is inactive.
