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).

CALC SMBL
Calculates a value based on the A
input source (A141 selects) and B
input source (A142 selects).
Three options:
00
…ADD (A input + B input)
01 …SUB (A input - B input)
02 …MUL (A input * B input)
U 00 00 −
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.
