5.7 H: Terminal Functions
n H3-11, H3-12: Terminal A2 Gain and Bias Setting
Parameter H3-11 sets the level of the input value selected that is equal to 10 Vdc input or 20 mA input to terminal A2.
Parameter H3-12 sets the level of the input value selected that is equal to 0 V, 4 mA or 0 mA input at terminal A2.
Use both parameters to adjust the characteristics of the analog input signal to terminal A2. The setting works in the same way
as parameters H3-03 and H3-04 for analog input A1.
No.
H3-11
H3-12
n H3-13: A1/A2 Input Filter Time Constant
Parameter H3-13 sets the time constant for a first order filter that will be applied to the analog inputs.
An analog input filter prevents erratic drive control when using a "noisy" analog reference. Drive operation becomes more
stable as the programmed time becomes longer, but it also becomes less responsive to rapidly changing analog signals.
No.
H3-13
n 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
n 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.
No.

Multi-Function Analog Input Terminal Settings
See Table 5.24 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.
