Notes:
• The [FBV] is designed for implementing two-stage
control. The PV high limit and PV low limit
parameters, C052 and C053, do not function as
process alarm thresholds. Terminal [FBV] does
not provide a PID alarm function.
• The example circuit for terminal [11] 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.
Function Name State
ON
OFF
C053
Description
• Transitions to ON when the inverter is in RUN
Mode and the PID Process Variable (PV) is less
than the Feedback Low Limit (C053)
• 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
