When a signal current is applied to terminals C4 and C5, a voltage is
developed across the terminals due to the input resistance supplied by
the termination resistor. The full-scale voltage is 2V which is produced
when the input current is 20mA and the termination resistor is 100
Ω
.
3
If a different input current is required to produce 2V full-scale voltage,
the 100
Ω
termination resistor can be replaced with a 0.5W resistor of a
suitable value.
4
If the Drive is used with the resistor removed, the input can be used as
a unipolar voltage input having a 2V full-scale value. Parameter
0.25
must then be set at
0.20
for 0-to-2V operation, or at
20.0
for 2V-to-0
operation.
