Terminal A3 Signal Level Select

Sets the input signal level for MFAI terminal A3.

0

(0 - 3)

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 H3-05 = 0, 1, set DIP switch S1-3 to the V side (voltage). When H3-05 = 2, 3, set DIP switch S1-3 to the I side (current). The default setting is the V side (voltage).
