The following figure shows how to set the relationship in F0-07, in which the bold line
indicates the default setting.

The operation 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 required frequency 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, as shown in
Figure 4-19. When the specied command source (F0-02) is bound to a frequency source
(corresponding digit in the value of F0-27), the frequency is determined by the frequency
setting channel set in F0-27. In this case, both main and auxiliary frequency sources are
ineffective.
