H3-14: Analog Input Terminal Enable Selection
When one of the multi-function digital input parameters is set for "Analog input enable" (H1- = 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- is not set to C.
No.
H3-14
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
Parameters H3-16 to H3-18 set the offset level of the selected input value to terminal A1, A2 or A3 that is equal to 0 Vdc
input. These parameters rarely need adjustment.
No.

Multi-Function Analog Input Terminal Settings
See Table 5.30 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.

<1> This function is available in models CIMR-E4A0930 and 4A1200.
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. Using A1 and A2 at the same time 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.
