H3-14: Analog Input Terminal Enable Selection
When one of the multi-function digital input parameters is set for "Analog input enable" (H1-oo = C), the value set to H3-14
determines which analog input terminals are enabled when the input is closed. All of the analog input terminals will be enabled
all of the time when H1-oo≠ C. The terminals not set as the target are not influenced by input signals.
No.

Setting 1: A1 Only Enabled
Setting 2: A2 Only Enabled
Setting 3: A1 and A2 Only Enabled
Setting 4: A3 Only Enabled
Setting 5: A1 and A3 Only Enabled
Setting 6: A2 and A3 Only Enabled
Setting 7: All Analog Input Terminals Enabled

H3-16 to H3-18: Terminal A1/A2/A3 Offset
Set the offset level of the selected input value to terminals A1, A2, or A3 that is equal to 0 Vdc input. These parameters rarely
require adjustment.

See
Table 1.33
for information on how H3-02, H3-10, and H3-06 determine functions for terminals A1, A2, and A3.
Note:
The scaling of all input functions depends on the gain and bias settings for the analog inputs. Set these to appropriate values when selecting
and adjusting analog input functions.

Setting 0: Frequency Bias
The input value of an analog input set to this function will be added to the analog frequency reference value. When the frequency
reference is supplied by a different source other than the analog inputs, this function will have no effect. Use this setting also
when only one of the analog inputs is used to supply the frequency reference.
By default, analog inputs A1 and A2 are set for this function. Simultaneously using A1 and A2 increases the frequency reference
by the total of all inputs.
Example: If the analog frequency reference from analog input terminal A1 is 50% and a bias of 20% is applied by analog input
terminal A2, the resulting frequency reference will be 70% of the maximum output frequency.
Setting 1: Frequency Gain
The input value of an analog input set to this function will be multiplied with the analog frequency reference value.
