426 YASKAWA SIEPYAIH6B01A HV600 AC Drive Bypass Technical Reference
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.
