Multi-reference
Multi-reference is a relative value and is a percentage of F0-10 (max. frequency).
Whether the setting is positive or negative determines drive running direction. If negative,
it indicates that the AC drive runs in reverse direction.
Multiple frequency references are set in group FC, as listed in the following table.

In multi-reference mode, combinations of different DI terminal states correspond to
different frequency references. The AC drive supports a maximum of 16 references
implemented by 16 state combinations of four DI terminals (allocated with functions 12 to
15) in Group FC.
If a DI terminal is used for the multi-reference function, you need to set related parameters
in group F4.
The below diagram Figure 6-20 shows an example of 4 multi-frequency settings.
