Multi-Function Analog Input Terminal Settings

This section gives information about the functions set with H3-02, H3-06, and H3-10.
■
0: Frequency Reference
Setting Value Function
0 Frequency Reference
• You can copy the configuration to more than one of the analog input terminals A1 through A3. When you set
more than one analog input terminal with the master frequency reference, the sum value becomes the frequency
bias.
• If you use this function to set the analog input value as the master frequency reference, set b1-01 = 1
[Frequency Reference Selection 1 = Analog Input]. This setting value is the default value for terminals A1 and
A2.
• The frequency reference is the sum of the input values for terminals A1 and A2 when they are used at the same
time. For example, when a 20% bias is input to terminal A2 while a frequency reference of 50% is input from
terminal A1, the calculated frequency reference will be 70% of the maximum output frequency.
■
1: Frequency Gain
Setting Value Function
1 Frequency Gain
Example: When you set frequency gain for terminal A2
• H3-10 = 1 [Terminal A2 Function Selection = Frequency Gain]
• A 50% frequency gain is input to terminal A2
• A frequency reference of 80% is input from terminal A1
The calculated frequency reference is 40% of the maximum output frequency.

2: Auxiliary Frequency Reference 1
Setting Value Function
2 Auxiliary Frequency

V/f CL-V/f OLV CLV AOLV
Sets the MEMOBUS AI3 function.
V/f CL-V/f OLV CLV AOLV
Sets the time constant to apply a primary delay filter to the MEMOBUS analog input register
values.
V/f CL-V/f OLV CLV AOLV
The input value from the MFAI terminal set with this function becomes the master frequency reference.
V/f CL-V/f OLV CLV AOLV
The drive multiplies the analog frequency reference with the input value from the MFAI set with this function.
V/f CL-V/f OLV CLV AOLV
Sets Reference 2 through multi-step speed reference to enable the command reference (Auxiliary Frequency Reference 1) from
the analog input terminal set here. This value is a percentage where the Maximum Output Frequency setting is a setting value of
100%.
V/f CL-V/f OLV CLV AOLV
Sets Reference 3 through multi-step speed reference to enable the command reference (Auxiliary Frequency Reference 2) from
the analog input terminal set here. This value is a percentage where the Maximum Output Frequency setting is a setting value of
100%.
