SINAMICS G120 Control Units CU240B/E-2 Parameter Manual (LH11), 01/2011
Description: Displays the currently referred input value of the analog inputs.
When interconnected, the signals are referred to the reference quantities p200x and p205x.
Index: [0] = AI0 (T. 3/4)
[1] = AI1 (T. 10/11)
Note: AI: Analog Input
T: Terminal
Description: Sets the type of analog inputs.
p0756[0...1] = 0, 1, 4 corresponds to a voltage input (r0752, p0757, p0759 are displayed in V).
p0756[0...1] = 2, 3 corresponds to a current input (r0752, p0757, p0759 are displayed in mA).
In addition, the associated DIP switch must be set.
For the voltage input, DIP switch AI0/1 must be set to "U".
For the current input, DIP switch AI0/1 or AI2 must be set to "I".
Value: 0: Unipolar voltage input (0 V ... +10 V)
1: Unipolar voltage input monitored (+2 V ... +10 V)
2: Unipolar current input (0 mA ... +20 mA)
3: Unipolar current input monitored (+4 mA to +20 mA)
4: Bipolar voltage input (-10 V ... +10 V)
8: No sensor connected
Index: [0] = AI0 (T. 3/4)
[1] = AI1 (T. 10/11)
Warning: The maximum voltage difference between analog input terminals AI+, AI-, and the ground must not exceed 35 V.
If the system is operated when the load resistor is switched on (DIP switch set to "I"), the voltage between differen-
tial inputs AI+ and AI- must not exceed 10 V or the injected 80 mA current otherwise the input will be damaged.
Note: When changing p0756 , the parameters of the scaling characteristic (p0757, p0758, p0759, p0760) are overwritten
with the following default values:
For p0756 = 0, 1, 4, p0757 is set to 0.0 V, p0758 = 0.0 %, p0759 = 10.0 V and p0760 = 100.0 %.
For p0756 = 2, p0757 is set to 0.0 mA, p0758 = 0.0 %, p0759 = 20.0 mA and p0760 = 100.0 %.
For p0756 = 3, p0757 is set to 4.0 mA, p0758 = 0.0 %, p0759 = 20.0 mA and p0760 = 100.0 %.
