Allen-Bradley PowerFlex 70 Reference Manual

Sleep Mode 2-163
Sleep Mode Operation
The basic operation of the Sleep-Wake function is to Start (wake) the drive
when an analog signal is greater than or equal to the user specified [Wake
Level], and Stop (sleep) the drive when an analog signal is less than or
equal to the user specified [Sleep Level]. Setting [Sleep-Wake Mode] to
“Direct” enables the sleep wake function.
Requirements
In addition to enabling the sleep function with [Sleep-Wake Mode], at least
one of the following assignments must be made to a digital input: Enable,
Stop-CF, Run, Run Fwd or Run Rev, and the input must be closed. All
normal Start Permissives must also be satisfied (Not Stop, Enable, Not
Fault, Not Alarm, etc.).
Conditions to Start/Restart
Table 2.AA Conditions Required to Start Drive

(1)
When power is cycled, if all conditions are present after power is restored, restart will occur.
(2)

The active speed reference is determined as explained in the User Manual. The Sleep/Wake function and the
speed reference may be assigned to the same input.
