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.
