Setting 1: -10 to 10 Vdc
The input level is -10 to 10 Vdc. Refer to
■ H3-10: Terminal A2 Function Selection
Determines the function assigned to analog input terminal A2. Refer to
on page 219 for a list of functions and descriptions.
No.
H3-10
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.
No.
H3-11
H3-12
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.
No.
H3-13
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.
No.
H3-16
H3-17
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.
