The following Figure 18 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 µC 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.
