Add Frequency Enable

The inverter can add or subtract an 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.
