Add Frequency – The inverter can add or subtract on offset value to the output
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 frequency setting only when
the [ADD] terminal is ON. Function  selects whether to add or subtract. By
configuring an intelligent input as the [ADD] terminal, your application can selectively
apply the fixed value in  to offset (positively or negatively) the inverter output
frequency in real time.
