Add Frequency – The inverter can add or subtract on offset value to the output
frequency setting which is specified by A001 (will work with any of the five possible
sources). The ADD Frequency is a value you can store in parameter A145. the ADD
Frequency is summed with or subtracted from the output frequency setting only when
the [ADD] terminal is ON. Function A146 selects whether to add or subtract. By
configuring an intelligent input as the [ADD] terminal, your application can selectively
apply the fixed value in A145 to offset (positively or negatively) the inverter output
frequency in real time.
