Analog Repeater Output
Analog signal repeater provides analog output signal scaled to selected analog input in any signal format.
For example, if ACI is set to 2-10VDC and AO to
6_ACI
, it will provide 0-10V or 4-20mA (whichever is
selected) output scaled to 2-10V. In this case, 2V Input = 0% (0V or 4mA) output and 10V input =100% (10V
or 20mA) output.
Auxiliary Analog Input
Auxiliary Analog Input (Aux AI) can be used by 2nd PID control, Trigger by Analog Level, and Freq Limit by
Analog Level features. Any analog input can be set as an Aux AI and can be scaled to appropriate value in
engineering units.
Set the following parameters:
Aux AI Signal [ADV2-58]:
Used for control features by analog level and 2nd PID Loop. Select AI input to
designate for Aux AI. Default = AVI1.
Aux AI Unit [ADV2-59]:
Select the units to be measured by the AI.
Aux Unit Format [ADV2-60]:
Select the precision of the AI units. This can be set to whole numbers, one
decimal place or two decimal places.
Aux Max Value [ADV2-61]:
the maximum value of the auxiliary input can be set from zero to 30000.
NOTE:
If using a PT100 or PTC for Aux AI, set the maximum value to 200 °C for PT100s and T
HIGH
for
PTCs.
Frequency Detection Trigger (FDT)
The VFD can provide a selected relay output control by five different types of frequency detection triggers
(FDT1 through FDT5). The function is activated when any relay output is set to
2 to 5
in parameters
[IO-47] ~
[IO-49]
.
FDT-1:
Select
2_FDT-1
for any relay output in
[IO-47] ~ [IO-49]
. It does not require any
other parameters for setup. VFD will activate a selected relay when output frequency
equals to the frequency command value.
FDT-2:
Select
3_FDT-2
for any relay output in
[IO-47] ~ [IO-49]
. It requires two fol
-
lowing parameters for setup:
FDT-2 Frequency [IO-52]:
VFD will activate a selected relay when output fre
-
quency is equal or greater than
[IO-52]
value.
FDT-2 Bandwidth [IO-53]:
VFD will deactivate relay when frequency becomes
less than
[IO-52]
minus
[IO-53]
value.
