limit
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
.

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 specifed command source
(
P0
-
02
)
is bound to a frequency source
(
corresponding digit in the value of P0
-
27
),
the frequency is determined by the frequency
setting channel set in P0
-
27
.
In this case
,
both main and auxiliary frequency sources are
ineffective
.
