12.8 H: Terminal Function Selection
672 YASKAWA SIEPC71061753C GA500 Technical Manual
■ H3-17: Terminal A2 Offset
No.
(Hex.)
Name Description
Default
(Range)
H3-17
(02F1)
Terminal A2 Offset
Sets the offset level for analog signals input to terminal A2. 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 [H3-09 = 2] or 0 mA
[H3-09 = 3] is input.
■ H3-40: Mbus Reg 15C1h Input Function
No.
(Hex.)
Name Description
Default
(Range)
H3-40
(0B5C)
Mbus Reg 15C1h Input
Function
Sets the MEMOBUS AI1 function.
F
(4 - 2F)
You can use the MFAI function from MEMOBUS/Modbus communications. Use this parameter to set the
function. Sets the function for MEMOBUS/Modbus register 15C1h.
Refer to H3: Analog Inputs on page 667 for the setting values.
■ H3-41: Mbus Reg 15C2h Input Function
No.
(Hex.)
Name Description
Default
(Range)
H3-41
(0B5F)
Mbus Reg 15C2h Input
Function
Sets the MEMOBUS AI2 function.
F
(4 - 2F)
You can use the MFAI function from MEMOBUS/Modbus communications. Use this parameter to set the
function. Sets the function for MEMOBUS/Modbus register 15C2h.
Refer to H3: Analog Inputs on page 667 for the setting values.
■ H3-42: Mbus Reg 15C3h Input Function
No.
(Hex.)
Name Description
Default
(Range)
H3-42
(0B62)
Mbus Reg 15C3h Input
Function
Sets the MEMOBUS AI3 function.
F
(4 - 2F)
You can use the MFAI function from MEMOBUS/Modbus communications. Use this parameter to set the
function. Sets the function for MEMOBUS/Modbus register 15C3h.
Refer to H3: Analog Inputs on page 667 for the setting values.
■ H3-43: Mbus Reg Inputs FilterTime Const
No.
(Hex.)
Name Description
Default
(Range)
H3-43
(117F)
Mbus Reg Inputs
FilterTime Const
Sets the time constant to apply a primary delay filter to the MEMOBUS analog input register
values.
0.00 s
(0.00 - 2.00 s)
◆ Multi-Function Analog Input Terminal Settings
This section gives information about the functions set with H3-02, H3-10, and H3-40 to H3-42.
■ 0: Frequency Reference
Setting Value Function Description
0 Frequency Reference
The input value from the MFAI terminal set with this function becomes the master frequency reference.
• You can copy the configuration to more than one of the analog input terminals A1 and A2. When you set more
than one analog input terminal with the master frequency reference, the sum value becomes the frequency bias.
