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 applications. You
can use the result for the output frequency setting (use A001=10) or for the PID Process
Variable (PV) input (use A075=03).
