3.1.2.10 Selecting Frequency Superposition Input Mode
The main and auxiliary frequency references can be used together for frequency
setting. You can use F0‑07 to set the relationship between the target frequency and
the main and auxiliary frequency references. The following four kinds of relationship
are available.
Table 3–3 Relationship between the target frequency and the main and auxiliary frequency
references
No.
Relationship Between the Target Frequency and the Main and Auxiliary Frequency References
1
Main frequency reference The main frequency reference is used as the target frequency reference.
2
Auxiliary frequency reference
The auxiliary frequency reference is used as the target frequency
reference.
3
Calculation of main and auxiliary
frequencies
Four calculation methods are supported: Main frequency + Auxiliary
frequency, Main frequency ‑ Auxiliary frequency, Max. (main frequency,
auxiliary frequency), and Min. (main frequency, auxiliary frequency).
4
Frequency switchover
The final frequency reference is selected from or switched among the
preceding three references through DI terminal. In this mode, assign DI
function 18 (Frequency source switchover) to the DI terminal.
