Note:
• Set this parameter to 0.0 to disable the function.
• Parameter YF-13 only applies to when YF-14 = 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-14 PI Aux Control Hi Level Det
Sel
(3F5D)
Note:
• Set YF-01 = 1 [PI Aux Control Selection = Enabled] and YF-12 [PI Aux Control High Level Detect] > 0 to enable PI Aux High Level
Detection.
• Parameter YF-13 only applies when YF-14 = 2 or 3
0 : NoDisplay (Digital Output Only)
When the PI Aux Feedback increases to more than the YF-12 level, the digital output set for H2-xx = 9F [MFDO
Function Selection = High PI Auxiliary Control Level] will immediately activate. When the level decreases to less
than the YF-12 level, the digital output will immediately deactivate.
1 : Alarm Only
When the PI Aux Feedback increases to more than YF-12 level, the keypad will show an HIAUX [High PI Aux
Feedback Level] alarm and the digital output set for H2-xx = 9F will activate. When the feedback decreases to less
than YF-12 level, the drive will clear the alarm and the digital output will deactivate.
2 : Fault
When the output frequency is more than zero, and the PI Aux Feedback increases to more than YF-12 level, the digital
output set for H2-xx = 9F and an HIAUX alarm will immediately activate. If the feedback stays more than the YF-12
level for the time set in YF-13 [PI Aux High Level Detection Time], the drive will then detect an HIAUX [High PI Aux
Feedback Level] fault.
3 : Auto-Restart (time set by YF-15)
When the output frequency is more than zero, and the PI Aux Feedback increases to more than YF-12 level, the digital
output set for H2-xx = 9F and an HIAUX alarm will immediately activate. If the feedback stays more than the YF-12
level for the time set in YF-13, the drive will then detect an HIAUX fault.
When L5-01 [Number of Auto-Restart Attempts] > 0 and if the drive detects an HIAUX fault, the drive will
automatically try an Auto-Restart after YF-15 [PI Aux Level Detect Restart Time] is expired. If the feedback is not
less than the YF-12 level, the Auto-Restart counter will increment and the drive will stay faulted.

V/f OLV/PM EZOLV OLV/PM
Sets the value above which the level must be for longer than YF-13 [PI Aux High Level Detection
Time] to respond as specified by YF-14 [PI Aux Hi Level Detection Select].
V/f OLV/PM EZOLV OLV/PM
Sets the length of time that the level must be more than YF-12 [PI Aux Control High Level Detect]
before the drive will respond when YF-14 = 2, 3 [PI Aux Hi Level Detection Select].
V/f OLV/PM EZOLV OLV/PM
Sets the drive response when the PI Aux Feedback increases to more than the YF-12 [PI Aux Control
High Level Detect] level for longer than the time set in YF-13 [PI Aux High Level Detection Time].
