Issue Number: 6
Defines the mode of analog input 1.
The table below gives all the possible analog input modes.
Pr 00.017 determines whether the reference is uni-polar or bi-polar.
See Minimum Reference Clamp (00.001). Allows negative speed reference in keypad mode.

6 Volt Voltage
In 4-20 mA and 20-4 mA modes loss of input is detected if the current falls below 3 mA.
If both analog inputs (A1 and A2) are to be set-up as voltage inputs, and if the
potentiometers are supplied from the drive's +10 V rail (terminal T3), they must have a
resistance >4 kΩ each.
