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).

Three options:

 

 

 

 

 

 

 

 

00ADD (A input + B input)

 

 

 

 

 

 

 

 

01SUB (A input - B input)

02MUL (A input * B input)

 

 

 

 

 

NOTE: For A141 and A142, it is not possible that you use [O] and [OI] together in calculation, because it is not allowed to use the both inputs at the same time on X200 series inverter.
