Connector: I/O communication [X1]
The following
shows the operating principle of the digital and analogue inputs and outputs. The item Servo
Positioning Controller C 3-Series is shown on the right and the control system connection on the left. The cable configuration is
also shown.
The item Servo Positioning Controller C 3-Series features two potential ranges:
Analogue inputs and outputs:
All of the analogue inputs and outputs refer to AGND. AGND is internally connected to GND, the reference potential for the
control module with
µ
C and AD converters in the servo positioning controller. This potential range is electrically isolated from
the 24 V range and from the DC bus circuit.
24 V inputs and outputs:
These signals refer to the 24 V supply voltage of the item Servo Positioning Controller C 3-Series, which is supplied via [X9].
They are separated from the reference potential of the control module by way of optocouplers.
