3.5.5 Connections of the analogue input module type SPC200−2AI−U
Two such modules can be installed in the basic unit type
SPC200−CPU−6. Each module possesses two differential inĆ
puts. The first module (inserted on the left) provides differenĆ
tial inputs 1 and 2; the second module provides differential
inputs 3 and 4. The module enables positions to be specified
in the form of a voltage (0...10 V).

The analogue inputs can be assigned to any axes and can be
activated by means of appropriate commands in the positionĆ
ing program. Various nominal value modes are supported
here (e.g. constant position adjustment, individual positionĆ
ing etc.).
