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.
■
YF-07: PI Aux Control Wake-up Time
No.
(Hex.)
Name Description
Default
(Range)
YF-07
(3F56)
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.
1 s
(0 - 3600 s)
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.
■
YF-08: PI Aux Control Minimum Speed
No.
(Hex.)
Name Description
Default
(Range)
YF-08
(3F57)
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. 0.00 Hz
(0.00 - 400.00 Hz)
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 .
■
YF-09: PI Aux Control Low Level Detect
No.
(Hex.)
Name Description
Default
(Range)
YF-09
(3F58)
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] .
0.0 PSI
(-999.9 - +999.9 PSI)
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.
■
YF-10: PI Aux Low Level Detection Time
No.
(Hex.)
Name Description
Default
(Range)
YF-10
(3F59)
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)] .
0.1 s
(0.0 - 300.0 s)
■
YF-11: PI Aux Control Low Level Det Sel
No.
(Hex.)
Name Description
Default
(Range)
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] .
