Terminal A1 Signal Level Select
|
        
Sets the input signal level for MFAI terminal A1.

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 H3-01 = 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).
