The diagram below shows how the Input/Output connections for the SJ–FB feedback board.
The inverter's internal connections and parameter configuration make these signals available on
intelligent input and output terminals.

.
The inverter can add or subtract an offset value to the output frequency setting which is speci-
fied 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.
