n H3-16, H3-17: Analog Input 1/2 Offset
Parameters H3-16 and H3-17 set the offset level of the selected input value to analog input 1 or 2 that is equal to 0 Vdc
input. These parameters rarely need adjustment.

Analog Input Terminal Settings
Refer to Tab le 2.28 for information on how H3-02 and H3-10 determine functions for analog inputs 1 and 2.
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.
Table 2.28 Analog Input Terminal Settings
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 1 and 2 are set for this function. Using analog inputs 1 and 2 at the same time increases the
frequency reference by the total of all inputs.
Example: If the analog frequency reference from analog input 1 is 50% and a bias of 20% is set for analog input 2, 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 by the analog frequency reference value.
Example: If the analog frequency reference from analog input 1 is 80% and a gain of 50% is applied from analog input 2,
the resulting frequency reference will be 40% of the maximum output frequency.
Setting 2: Auxiliary reference 1
Sets the auxiliary frequency reference 1 when multi-step speed operation is selected. Refer to Multi-Step Speed Selection
on page 140 for details.
Setting 3: Auxiliary reference 2
Sets the auxiliary frequency reference 2 when multi-step speed operation is selected. Refer to Multi-Step Speed Selection
on page 140 for details.
Setting 4: Output voltage bias
Voltage bias boosts the output voltage of the V/f curve as a percentage of the maximum output voltage (E1-05). Available
only when using V/f Control.
No. Name Setting Range Default
H3-16 Analog input 1 offset -500 to 500 0
H3-17 Analog input 2 offset -500 to 500 0
