AI2 Bias Setting
Sets the bias of the analog signal input to MFAI terminal AI2.
0.0%
(-999.9 - +999.9%)
When 0 V (4 mA or 0 mA) is input, this parameter sets the bias for the function set for terminal AI2 as a
percentage.
Use this parameter and H3-11 [AI2 Gain Setting] to adjust the characteristics of the analog input signal to terminal
AI2.
■ H3-13 An.In FilterTime Constant
No.
(Hex.)
Name Description
Default
(Range)
H3-13
(041B)
An.In FilterTime Constant
Sets the time constant to apply a primary delay filter to the MFAI terminal.
0.03 s
(0.00 - 2.00 s)
Apply the primary delay filter to the analog input to enable an analog input signal without the use of high-
frequency noise components. An analog input filter prevents irregular drive control. Drive operation becomes
more stable as the programmed time becomes longer, but it also becomes less responsive to quickly changing
analog signals.
■ H3-14 An.In Term.Enable Sel
No.
(Hex.)
Name Description
Default
(Range)
H3-14
(041C)
An.In Term.Enable Sel
Sets the enabled terminal or terminals when H1-xx: MFDI Function Select = 12 [AI Input Sel] is
ON.
7
(1 - 7)
Input signals do not have an effect on terminals not set as targets.
1 : AI1 only
2 : AI2 only
3 : AI1 and AI2
4 : AI3 only
5 : AI1 and AI3
6 : AI2 and AI3
7 : AI1, AI2, and AI3
Note:
• The ON/OFF operation of terminal DIx set in AI Input Sel [H1-xx = 12] has an effect on only the analog input terminal selected with
H3-14.
• When H1-xx ≠ 12, the functions set to terminals AI1 to AI3 are always enabled.
■ H3-16 AI1 Offset
No.
(Hex.)
Name Description
Default
(Range)
H3-16
(02F0)
AI1 Offset
Sets the offset level for analog signals input to terminal AI1. Usually it is not necessary to change
this setting.
0
(-500 - +500)
Adds the offset value for the analog input value. For voltage input, this parameter will set the offset when a signal
of 0 V is input. For current input, this parameter will set the offset when a signal of 4 mA [H3-01= 2] or 0 mA
[H3-01 = 3] is input.
■ H3-17 AI2 Offset
No.
(Hex.)
Name Description
Default
(Range)
H3-17
(02F1)
AI2 Offset
Sets the offset level for analog signals input to terminal AI2. Usually it is not necessary to change
this setting.
