Connection: I/O communication [X1]
The following
shows the principle function of the digital and analog inputs and outputs. The item servo positioning
controller C 1-Series is shown on the right hand side, the control system connection on the left. The cable design is also visible.
The item servo positioning controller C 1-Series features two potential ranges:
Analog inputs and outputs:
All analog inputs and outputs refer to AGND. AGND is internally connected with GND, the reference potential for the control
module with
µ
C and AD converters in the controller. This potential range is galvanically separated from the 24 V range and
from the DC bus.
24 V inputs and outputs:
These signals refer to the 24 V supply voltage of the item servo positioning controller C 1-Series which is fed via [X9], and
separated from the reference potential of the control module by means of optocouplers.
