Description
07 FBV Feedback Value
Check
ON
Transitions to ON when the inverter is in RUN
Mode and the PID Process Variable (PV) is
less than the Feedback Low Limit (C053)
OFF
Transitions to OFF when the PID Feedback
Value (PV) exceeds the PID High Limit
(C052)
Transitions to OFF when the inverter goes
from Run Mode to Stop Mode
Valid for outputs:
11, 12, AL0 – AL2
Required settings:
A076, C052, C053
Notes:
The [FBV] is designed for implementing two-stage
control. The PV high limit and PV low limit param-
eters, C052 and C053, do not function as process
alarm thresholds. Terminal [FBV] does not provide
a PID alarm function.
The example circuit for terminal [12] drives a relay
coil. Note the use of a diode to prevent the negative-
going turn-off spike generated by the coil from
damaging the inverter’s output transistor.
