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.

Required settings
A001, A145, A146
Notes:
• A001 may specify any source; the Add Frequency
will be added to or subtracted from that value to
yield output frequency value.
