Analog Input Calculate Function – The inverter can mathematically combine two
input sources into one value. The Calculate function can either add, subtract, or multiply
the two selected sources. This provides the flexibility needed by various applica-
tions.You can use the result for the output frequency setting (use A001=10) or for the
PID Process Variable (PV) input (use A075=03).
