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 =) or for the PID Process Variable (PV) input (use =).

Add Frequency - The inverter can add or subtract on offset value to the out-
put frequency setting which is specified by  (will work with any of the five
possible sources). The ADD Frequency is a value you can store in parameter
. the ADD Frequency is summed with or subtracted from the output fre-
quency setting only when the [ADD] terminal is ON. Function  selects
whether to add or subtract. By configuring an intelligent input as the [ADD] ter-
minal, your application can selectively apply the fixed value in  to offset
(positively or negatively) the inverter output frequency in real time.
