MFAI Setting Value

This section gives information about the functions set with H3-02 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 and A2. 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 you use them at the same
time. For example, when you input a 20% bias to terminal A2 and input a frequency reference of 50% from
terminal A1, the calculated frequency reference will be 70% of the maximum output frequency.
■
1: Frequency Gain
Setting Value Function
1 Frequency Gain
298
Sets the MEMOBUS AI1 function.
Sets the MEMOBUS AI2 function.
Sets the MEMOBUS AI3 function.
Sets the time constant to apply a primary delay filter to the MEMOBUS analog input register values.
The input value from the MFAI terminal set with this function becomes the master frequency reference.
The drive multiplies the analog frequency reference with the input value from the MFAI set with this function.
