Notes:				Inverter output
ξ The [FBV] is designed for implementing two-				terminal circuit	FBV
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.				CM2	11

ξThe 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			RY
coil from damaging the inverter’s output
transistor.
