SINAMICS G120 CU240B/E-2 Control Units List Manual (LH11), 01/2013

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, 4, p0757 is set to 0.0 V, p0758 = 0.0 %, p0759 = 10.0 V and p0760 = 100.0 %.

For p0756 = 1, p0757 is set to 2.0 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 %.

Description: Sets the scaling characteristic for the analog inputs.

The scaling characteristic for the analog inputs is defined using 2 points.

This parameter specifies the x coordinate (V, mA) of the 1st value pair of the characteristic.

Index: [0] = AI0 (T. 3/4)

[1] = AI1 (T. 10/11)

Note: The parameters for the characteristic do not have a limiting effect.
