“A” Group: Standard Functions

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).
