SIEPYAIH6B01A HV600 AC Drive Bypass Technical Reference
425
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
.
0 : No Display
When the PI Aux Feedback decreases to less than the
YF-09 [PI Aux Control Low Level Detect]
level, the digital
output set for
H2-xx = 9E [MFDO Function Selection = Low PI Auxiliary Control Level
will activate. When the level
increases to more than the
YF-09
level, the digital output will immediately deactivate.
1 : Alarm Only
When the PI Aux Feedback decreases to less than
YF-09
level, the keypad will show an
LOAUX [Low PI Aux
Feedback Level]
alarm and the digital output set for
H2-xx = 9E
will activate. When the feedback increases to more
than
YF-09
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 decreases to less than the
YF-09
level, the
digital output set for
H2-xx = 9E
and an
LOAUX
alarm will immediately activate. If the feedback stays less than the
YF-09
level for the time set in
YF-10 [PI Aux Low Level Detection Time]
, the drive will detect an
LOAUX [Low 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 decreases to less than the
YF-09
level, the
digital output set for
H2-xx = 9E
and an
LOAUX
alarm will immediately activate. If the feedback stays less than the
YF-09
level for the time set in
YF-10 [PI Aux Low Level Detection Time]
, the drive will detect an
LOAUX
fault.
When
L5-01 [Number of Auto-Restart Attempts]
> 0 and if the drive detects an
LOAUX
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
more than the
YF-09
level, the Auto-Restart counter will increment and the drive will stay faulted.
