5.7 H: Terminal Functions
236 YASKAWA ELECTRIC SIEP C710616 27C YASKAWA AC Drive A1000 Technical Manual
When analog input A3 is used as PTC input set H3-06 = E and make sure switch S4 on the terminal board is set for PTC
input. Also refer to Terminal A3 Analog/PTC Input Selection on page 79.
■
H3-07, H3-08: Terminal A3 Gain and Bias Setting
Parameter H3-07 sets the level of the selected input value that is equal to 10 Vdc input at terminal A3 (gain).
Parameter H3-08 sets the level of the selected input value that is equal to 0 V input at terminal A3 (bias).
■
H3-09: Terminal A2 Signal Level Selection
Selects the input signal level for analog input A2. Be sure to also set DIP switch S1 on the terminal board accordingly for
a voltage input or current input.
Setting 0: 0 to 10 Vdc
The input level is 0 to 10 Vdc. Refer to Setting 0: 0 to 10 Vdc on page 234
Setting 1: –10 to 10 Vdc
The input level is –10 to 10 Vdc. Refer to Setting 1: –10 to 10 Vdc on page 234.
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%.
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%.
■
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 237 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 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.
Both can be used 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.
■
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 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.
