Frequency source reference is achieved by compounding frequency source master
setting and frequency source auxiliary setting
Units digit: frequency source selection:
0: Frequency source master setting
Frequency source master setting is used as command frequency
1: Arithmetic result of master and auxiliary is used as command frequency, for the
arithmetic relationship of master and auxiliary, please see the instructions of function code
"tens digit".
2: Switch between frequency source master setting and auxiliary setting, when multi-
function input terminal 18 (frequency switching) is invalid, the frequency source master
setting is selected as command frequency. when multi-function input terminal 18 (frequency
switching) is valid, frequency source auxiliary setting is selected as command frequency.
3: Switch between the frequency source master setting and the arithmetic result of
master and auxiliary, when multi-function input terminal 18 (frequency switching) is invalid,
the frequency source master setting is selected as command frequency. When multi-function
input terminal 18 (frequency switching) is valid, the arithmetic result of master and auxiliary
is selected as command frequency.
4: Switch between the frequency source auxiliary setting and the arithmetic result of
master and auxiliary, when multi-function input terminal 18 (frequency switching) is invalid,
the frequency source auxiliary setting is selected as command frequency. When multi-
function input terminal 18 (frequency switching) is valid, the arithmetic result of master and
auxiliary is selected as command frequency.
Tens digit: arithmetic relationship of master and auxiliary for frequency source
0: frequency source master setting + frequency source auxiliary setting
The sum of frequency source master setting plus frequency source auxiliary setting is
used as command frequency Achieve frequency overlay reference function.
1: frequency source master setting - frequency source auxiliary setting
The difference of frequency source master setting minus frequency source auxiliary
setting is used as command frequency
