H3: Mfai Parameters - YASKAWA GA800 Technical Reference

Note:
• Refer to H3-xx "MFAI Setting Values" for the analog input setting values.
• When you will not use the terminal, set H3-40 to H3-42 = F. The through mode function is not supported.
• You cannot use H3-40 to H3-42 to set these MFAI terminals:

H3-01 Terminal A1 Signal Level
Select
(0410)
0 : 0-10V (Lower Limit at 0)
The voltage signal is 0 Vdc to 10 Vdc. The minimum input level limit is 0%. The drive will read a negative input
signal caused by gain and bias settings as 0%.
1 : -10 to +10V (Bipolar Reference)
The voltage signal is -10 Vdc to 10 Vdc. Signals of both positive and negative polarities are enabled. When the drive
uses this setting as the frequency reference, a Forward Run command will run the motor in reverse and a Reverse Run
command will run the motor forward. The gain and bias settings will cause the signal to be a negative number.
2 : 4 to 20 mA
The current signal is 4 mA to 20 mA. The minimum input level limit is 0%. 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%.
3 : 0 to 20 mA
The current signal is 0 mA to 20 mA. The minimum input level limit is 0%. 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%.
Note:
When H3-01 = 0, 1, set DIP switch S1-1 to the V side (voltage). When H3-01 = 2, 3, set DIP switch S1-1 to the I side (current). The default
setting is the V side (voltage).
