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 and which terminals are disabled when the input is closed. All analog

input terminals will be enabled all of the time if H1-oo is not set to C.

No. Name Setting Range Default

H3-14 Analog Input Terminal Enable Selection 1 to 3 2

Setting 1: A1 Only Enabled

Setting 2: A2 Only Enabled

Setting 3: Terminals A1 and A2

H3-16 and H3-17: Terminal A1/A2 Offset

Set the offset level of the selected input value to terminals A1 or A2 that is equal to 0 Vdc input. These parameters rarely

require adjustment.

No. Name Setting Range Default

H3-16 Terminal A1 Offset -500 to 500 0

H3-17 Terminal A2 Offset -500 to 500 0

Multi-Function Analog Input Terminal Settings

See Table 5.22 for information on how H3-02 and H3-10 determine functions for terminals A1 and A2.

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.

Example: If the analog frequency reference from analog input terminal A1 is 80% and a gain of 50% is applied from analog

input terminal A2, 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 142 for details.
