MEMOBUS Multi-Function AI1 to 3 Function Selection
Allows the MFAI function to be assigned to MEMOBUS register15C1 to 15C3 (Hex.) [MEMOBUS Multi-
Function AI1 to AI3 Command]. Select the function with H3-40 to H3-42 [Extend MFAI1 to MFAI3 function
selection] and set the input filter with H3-43 [Fiter time for MFAI].

Note:
• Refer to H3-xx "MFAI Setting Values" for the analog input setting values.
• Set H3-40 to H3-42 = F when not using the terminal. The through mode function is not supported.
• The following MFAI terminals cannot be selected with H3-40 to H3-42.

H3-01 Terminal A1 Signal
Level Select
(0410)
0 : 0-10V (LowLim=0)
The voltage signal is 0 Vdc to 10 Vdc. The minimum input level is limited to 0%, so that a negative input signal
due to gain and bias settings will be read as 0%.
1 : 0-10V (BipolRef)
The voltage signal is 0 Vdc to 10 Vdc. Signals of both positive and negative polarities are enabled. When this
setting is used as the frequency reference, the motor runs reverse when the Forward run command is input, or runs
forward when the Reverse run signal is input, while the signal is a negative number due to gain and bias.
2 : 4-20 mA
The current signal is 4 mA to 20 mA. The minimum input level is limited to 0%, so that a negative input signal
due to gain and bias settings will be read as 0%.
