5.7 H: Terminal Functions
YASKAWA ELECTRIC SIEP C710616 38F YASKAWA AC Drive - L1000A Technical Manual 219
Setting 1: -10 to 10 Vdc
The input level is -10 to 10 Vdc. Refer to Setting 1: -10 to 10 Vdc on page 217 for details.

H3-10: Terminal A2 Function Selection
Determines the function assigned to analog input terminal A2. Refer to Multi-Function Analog Input Terminal Settings
on page 219 for a list of functions and descriptions.
■
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 to terminal A2.
Parameter H3-12 sets the level of the input value selected that is equal to 0 V at terminal A2.
Both can be used to adjust the characteristics of the analog input signal to terminal A2. The settings work in the same way
as parameters H3-03 and H3-04 for analog input A1.
■
H3-13: Analog 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.
■
H3-16/H3-17: Offset for Terminal A1/A2
Parameters H3-16 and H3-17 set the offset applied analog input values from terminals A1 and A2.
Although adjustment is rarely required, these parameters can be used for zero adjustment of the analog inputs.
■
Multi-Function Analog Input Terminal Settings
Refer to Table 5.13 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.
