3.5.6 Connections of the sub−controller module type SPC200−SCU−AIF
In its basic design, the SPC200 can take control of the posiĆ
tioning of two pneumatic axes. With the sub−controller modĆ
ule maximum four pneumatic axes can be operated with one
SPC200. The sub−controller module provides a connection for
a second axis interface string and controls the positioning of
the connected axes. Maximum two pneumatic axes per axis
interface string are permitted.
Caution
Use the special cables from Festo (type KSPC−AIF−...)
for connecting the axis interface. Note the maximum
permitted cable lengths on the axis interface string
(see section 3.6).
You can then avoid functional faults on the SPC200 and on
the modules connected to the axis interface string.
The bus signals, the operating voltage and the load voltage
for the connected field devices are provided via the 5−pin
plug of the power supply module. Connecting cable type
KSPC−AIF−... is supplied already fitted with a 5−pin screw
terminal.
Caution
The axis interface connection is not protected against inĆ
correct polarity. Make sure that the assignment is correct,
e.g. when you fit the screw terminal yourself after shortenĆ
ing the cable.
