RUN
PI Aux Control Minimum
Level
Sets the level below which the drive must be for longer than YF-05 [PI Aux Control Sleep
Delay Time] before the drive goes to sleep and turns off all lag pumps.
Note:
• Set this parameter to 0.0 to disable the function.
• Parameters YF-21 [PI Aux Ctrl Level Unit Selection] and YF-22 [PI Aux Level
Decimal Place Pos] set the unit and resolution.

RUN
PI Aux Control Sleep
Delay Time
Sets the length of time that the drive will delay before it goes to sleep after the level is less
than YF-04 [PI Aux Control Minimum Level] (when YF-23 = 1 [PI Aux Ctrl Output Level
Select = Inverse Acting]) or more than YF-24 [PI Auxiliary Ctrl Maximum Level] (when
YF-23 = 0 [Direct Acting]).

RUN
PI Aux Control Wake-up
Level
Sets the level to wake up the drive when the drive after YF-04 [PI Aux Control Minimum
Level] or YF-24 [PI Auxiliary Ctrl Maximum Level] put the drive to sleep.
Note:
• Parameter YF-23 [PI Aux Ctrl Output Level Select] sets the condition to wake up the
drive.
–YF-23 = 0 [Direct Acting]: The PI Aux Feedback must be less than the level set in
this parameter for longer than the time set in YF-07 to wake up.
–YF-23 = 1 [Inverse Acting]: The PI Aux Feedback must be more than the level set
in this parameter for longer than the time set in YF-07 [PI Aux Control Wake-up
Time] to wake up.
• Parameters YF-21 [PI Aux Ctrl Level Unit Selection] and YF-22 [PI Aux Level
Decimal Place Pos] set the unit and resolution.

PI Aux Control Wake-up
Time
Sets the time to wake up the drive when the drive after YF-04 [PI Aux Control Minimum
Level] or YF-24 [PI Auxiliary Ctrl Maximum Level] put the drive to sleep.
Note:
Parameter YF-23 [PI Aux Ctrl Output Level Select] sets the condition to wake up the
drive.
• YF-23 = 0 [Direct Acting]: The PI Aux Feedback must be less than the level set in
YF-06 for longer than the time set in YF-07 to wake up.
• YF-23 = 1 [Inverse Acting]: The PI Aux Feedback must be more than the level set in
YF-06 [PI Aux Control Wake-up Level] for longer than the time set in YF-07 to wake
up.

RUN
PI Aux Control Minimum
Speed
Sets the minimum speed at which the drive can run when the PI Auxiliary Control has an
effect on the output speed.
Note:
The drive will use Y1-06 [Minimum Speed] and Y4-12 [Thrust Frequency] as the
minimum speed when PI Aux Control does not have an effect on the output speed or
when you set YF-08 < Y1-06 and Y4-12.

RUN
PI Aux Control Low
Level Detect
Sets the level below which the drive must be for longer than YF-10 [PI Aux Control Low
Lvl Det Time] to respond as specified by YF-11 [PI Aux Control Low Level Det Sel].
Note:
• Set this parameter to 0.0 to disable the function.
• Parameter YF-10 only applies to when YF-11 = 2 and 3 [Fault and Auto-Restart
(time set by YF-15)].
• Parameters YF-21 [PI Aux Ctrl Level Unit Selection] and YF-22 [PI Aux Level
Decimal Place Pos] set the unit and resolution.

RUN
PI Aux Low Level
Detection Time
Sets the length of time that the PI Aux Feedback must be less than YF-09 [PI Aux Control
Low Lvl Detection] to trigger a drive response when YF-11 = 2 and 3 [PI Aux Control Low
Level Det Sel = Fault and Auto-Restart (time set by YF-15)].

YF-11
(3F5A)
PI Aux Control Low
Level Det Sel
Sets drive response when the PI Aux Feedback decreases to less than YF-09 [PI Aux
Control Low Lvl Detection] for longer than YF-10 [PI Aux Control Low Lvl Det Time].
0 : No Display
1 : Alarm Only
2 : Fault
3 : Auto-Restart (time set by YF-15)
Note:
• Set YF-01 = 1 [PI Aux Control Selection = Enabled] and YF-09 [PI Aux Control
Low Level Detect] > 0 to enable PI Aux Low Level Detection.
• Parameter YF-10 only applies when YF-11 = 2 or 3.
