rameter settings are enabled. If "frequency gain" is set for the multi-function
analog input, it is multiplied by n060; if "frequency bias" is set, it is added to
n061.
The relationship between the multi-function analog input's input voltage and

Value
0 Enable multi-function analog voltage inputs. (Disable current inputs.)
1 Enable multi-function analog current inputs. (Disable voltage inputs.)

Disables multi-function analog inputs.
Set "0" when setting multi-function inputs with n004
(Frequency Reference Selection) or n164 (PID Feedback
Input Block Selection). If this function is allocated for both, an
error (err or oP6) will be generated.
Sets the terminal to be used as a second analog frequence
reference terminal. The analog input from the multi-function
analog input becomes the frequency reference in place of
Frequency Reference 2. Toggle the two analog inputs with
the multi-function input's multi-step speed references.
When this function is set, Frequency Reference 2 (n025) is
ignored.
Adjusts the gain for frequency references that are input to the
frequency reference input (analog) terminal.
0 to 10 V (4 mA, or 0 mA to 20 mA): 0x to 2x (See note 2.)
Adjusts the bias for frequency references that are input to the
frequency reference input (analog) terminal.
0 to 10 V (4 mA, or 0 mA to 20 mA): --n079 SV to +n079 SV
(See note 2.)
Adjusts the Inverter's output voltage bias. The bias value that
is input is added to the output voltage value for the normal
V/f setting.
0 to 10 V (4 mA, or 0 mA to 20 mA): 0 V to +100 V
