12.7 H: TERMINALS
738 SIEPYEUOQ2A01G AC Drive Q2A Technical Manual
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 [H3-09 = 2] or 0 mA
[H3-09 = 3] is input.
■ H3-18 AI3 Offset
No.
(Hex.)
Name Description
Default
(Range)
H3-18
(02F2)
AI3 Offset
Sets the offset level for analog signals input to terminal AI3. 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 [H3-05 = 2] or 0 mA
[H3-05 = 3] is input.
■ H3-40 15C1h Input Function
No.
(Hex.)
Name Description
Default
(Range)
H3-40
(0B5C)
15C1h Input Function
Sets the Modbus AI1 function.
0
(0, 3, 6 - 2F)
You can use the MFAI function from Modbus communications. Use this parameter to set the function. Sets the
input for the function in Modbus register 15C1. Refer to H3-xx “MFAI Setting Values” for the setting values.
■ H3-41 15C2h Input Function
No.
(Hex.)
Name Description
Default
(Range)
H3-41
(0B5F)
15C2h Input Function
Sets the Modbus AI2 function.
0
(0, 3, 6 - 2F)
Refer to H3-xx “MFAI Setting Values” for the setting values.
■ H3-42 15C3h Input Function
No.
(Hex.)
Name Description
Default
(Range)
H3-42
(0B62)
15C3h Input Function
Sets the Modbus AI3 function.
0
(0, 3, 6 - 2F)
Refer to H3-xx “MFAI Setting Values” for the setting values.
■ H3-43 Mbus In FilterTime Const
No.
(Hex.)
Name Description
Default
(Range)
H3-43
(117F)
Mbus In FilterTime Const
Sets the time constant to apply a primary delay filter to the Modbus analog input terminal.
0.00 s
(0.00 - 2.00 s)
◆ Multi-Function Analog Input Setting Values
This section gives information about the functions set with H3-02, H3-06, and H3-10.
■ 0: Through Mode
Setting Function Description
0 Through Mode
Value for terminals that are not being used or terminals being used in through mode.
When you set a terminal that is not in use to 0, you can use the signal input to the terminal as PLC analog signal
input through Modbus communications or the communication option. This input signal does not have an effect on
drive operation. This functions the same as setting 100 (Through Mode).
