4.1.2.10 Selecting Source of Main Frequency and Auxiliary Frequency Superposition Reference
Main and auxiliary frequency reference superposition is used to set the frequency reference by
combining the main frequency reference and auxiliary frequency reference. The relationship between
the target frequency and the main and auxiliary frequency references is set in F0-07, which is described
as follows.
Table 4–5 Relationship between target frequency and main and auxiliary frequency references
No.
Relationship Between Target Frequency and Main and Auxiliary Frequency References
1
Main frequency reference
The main frequency reference is directly used as the target
frequency.
2
Auxiliary frequency reference
The auxiliary frequency reference is directly used as the target
frequency.
3
Main and auxiliary operation
There are 5 types of main and auxiliary operations: main
frequency + auxiliary frequency, main frequency – auxiliary
frequency, MAX (main frequency, auxiliary frequency), MIN (main
frequency, auxiliary frequency), and main frequency x auxiliary
frequency.
4
Frequency switchover
Any of the preceding three frequency sources selected or
switched by using the DI terminal. The DI terminal must be
assigned with function 23 (frequency reference switchover).
