The table below gives all the possible analog input modes.
Pr

determines whether the reference is uni-polar or bi-polar. See
Minimum Speed
(Pr
01
). Allows
negative speed reference in keypad mode.
If the preset reference has been selected (see Pr
05
), the speed at which the motor runs is
determined by these parameters. See
Drive Configuration
(Pr
05
).

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 T4), they must have a
resistance >4 k
Ω
each.
