Refer to parameter A011 to A015 for analog voltage input.
Analog Input Calculate Function - The inverter can mathematically combine
two input sources into one value. The Calculate function can either add, sub-
tract, 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).
