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.
Set n077 to 0 to disable the multi-function analog input function when
enabling PID control in n128 (PID Control Selection). If this function is not
disable when PID control is being used, an error 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) parameter 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.)
•
When setting “3” (frequency bias) for the multi-function analog input terminal function selection
(n077), set the standard value for the bias in n079. Make the setting as a percentage, with the maxi-
mum frequency (n011) as100%.
