Expansion Card
Input Signals
Other inputs listed below require the expansion card SJ-FB Encoder Feedback. Please see the
SJ-FB manual for more information.
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 information on outputs related to the SJ-FB expansion card is in
“Expansion Card Output
Signals” on page 4–54
.
ADD Frequency
Enable
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.
