The relationship between the frequency reference and the main frequency source and
auxiliary frequency source is set in F0-07, as follows:
1. Main frequency source X: The main frequency source is directly used to set the frequency
reference.
2. Auxiliary frequency source Y: The auxiliary frequency source is directly used to set the
frequency reference.
3. X and Y superposition: X+Y, X-Y, maximum of X and Y, and minimum of X and Y.
4. Frequency switchover: A DI terminal is used to switch over amongst the preceding three
frequency reference setting modes.
The following figure shows how to set the relationship in F0-07, in which the bold line
indicates the default setting.

Superposition between the main frequency source and the auxiliary frequency source can
be used for closed-loop speed control. For example, using the main frequency source
for setting the main frequency reference and the auxiliary frequency source for automatic
adjustment, in conjunction with switchover performed by the external DI terminal signal, the
required closed-loop control can be implemented.
4.8.3 Binding Command Source to Frequency Source
The three command sources can be separately bound to frequency sources in F0-27, as

source (corresponding digit in the value of F0-27), the frequency reference is determined by
the frequency setting channel set in F0-27. In this case, both main and auxiliary frequency
sources are ineffective.
