Allen-Bradley PowerFlex 70 Enhanced Control User Manual

96 Sleep Mode
Sleep Mode The purpose of the Sleep-Wake function is to Start (wake) the drive when an
analog signal is greater than or equal to the specified [Wake Level], and Stop
(sleep) the drive when an analog signal is less than or equal to the specified [Sleep
Level]. Setting [Sleep-Wake Mode] to “Direct” enables the sleep-wake function to
work as described.
An “Invert” mode also exists, which changes the logic so that an analog value less
than or equal to [Wake Level] starts the drive and an analog value greater than or
equal to [Sleep Level] stops the drive.
Sleep/Wake Operation
