For n077, select from the following five functions allocated to the multi-function analog input
terminal.
n077 Set Values
Value
Name
Description
0
Multi-function
Analog Input
Function Disable
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.
1
Auxiliary
Frequency
Reference
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.
2
Frequency Gain
(See note 1.)
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.)
3
Frequency Bias
(See note 1.)
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.)
4
Output Voltage
Bias
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
(See note 2.)
Note 1.
The frequency reference gain (n060) and frequency reference bias (n061) pa-
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.
Note 2.
The relationship between the multi-function analog input’s input voltage and
control variable is shown for when the frequency reference and multi-function
analog input gain are 100%, and when the bias setting is 0%.
·
For n078, select whether select whether voltage inputs or current inputs are to be
used.
Value
Description
0
Enable multi-function analog voltage inputs. (Disable current inputs.)
1
Enable multi-function analog current inputs. (Disable voltage inputs.)
