YASKAWA ELECTRIC
SIEP C710606 44B YASKAWA AC Drive T1000V Technical Manual
Setting 1: 0 to 10 Vdc without Lower Limit
The input level is 0 to 10 Vdc. Negative input values will be accepted. Refer to the explanation of H3-01, Setting 1.
to Setting 1: 0 to 10 Vdc without Limit on page 178
Setting 2: 4 to 20 mA Current Input
The input level is 4 to 20 mA. Negative input values by negative bias or gain settings will be limited to 0 (like setting 0).
Setting 3: 0 to 20 mA Current Input
The input level is 0 to 20 mA. Negative input values by negative bias or gain settings will be limited to 0 (like setting 0).

H3-10: Terminal A2 Function Selection
Determines the function assigned to analog input terminal A2.
Refer to Multi-Function Analog Input Terminal Settings
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 selected input value that is equal to 10 Vdc/20 mA input at terminal A2 (Gain).
Parameter H3-12 sets the level of the selected input value that is equal to 0 Vdc/4 mA/0 mA input at terminal A2.
Both can be used to adjust the analog input A2 characteristics. The setting works 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 both analog inputs A1 and A2.
An analog input filter can be used to prevent erratic drive control when a “noisy” analog reference is used. The drive
operation becomes more stable the longer the time programmed, but it becomes less responsive to rapidly changing
analog signals.

Multi-Function Analog Input Terminal Settings
This section describes the various functions that can be assigned to terminal A1 and A2 by setting H3-02 and H3-10.
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.
