Application Notes Appendix D-15
Start At PowerUp
Standard Control Option
Figure D.16 – Sleep Wake Mode
!
ATTENTION:Be aware of the following:
• Setting parameter 168 to 1 (Enabled) immediately applies output
power to the motor when all start conditions are met.
• If the drive is running from the terminal block, Start At PowerUp is
enabled, and a fault occurs, the drive coasts to rest and generates a
fault. In this case, resetting and clearing the fault immediately restarts
the drive without any change to the start or stop input states.
When this function is enabled, the user must ensure that automatic start
up of the driven equipment will not cause injury to operating personnel
or damage to the driven equipment. In addition, the user is responsible
for providing suitable audible or visual alarms or other devices to
indicate that this function is enabled and the drive may start at any
moment. Failure to observe this precaution could result in severe bodily
injury or loss of life.

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?
