ITEM C 3-Series User Manual

Electrical installation
Page 85
The item Servo Positioning Controller C 3-Series has one differential (AIN 0) and two single-ended analogue inputs for input
voltages in the range of ±10 V. The inputs AIN 0 and #AIN 0 are led to the control system via twisted cables (twisted-pair type).
If the control system is equipped with single-ended outputs, the output is connected to AIN 0 and #AIN 0 is connected to the
reference potential of the control system. If the control system is equipped with differential outputs, they are to be connected
1:1 to the differential inputs of the item Servo Positioning Controller C 3-Series.
The reference potential AGND is connected to the reference potential of the control system. This is necessary in order to
prevent the differential input of the item Servo Positioning Controller C 3-Series from being overridden by high "common-mode
interference".
There are two analogue monitor outputs with output voltages in the range of ± 10 V and one output for a reference voltage of
+10 V. These outputs can be led to the superordinate control system; the reference potential AGND must be carried along. If
the control system is equipped with differential inputs, the "+" input of the control system is connected to the output of the item
Servo Positioning Controller C 3-Series and the "-" input of the control system to AGND.
