ADD Frequency – 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 config-
uring 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.
