Analog input (CU310-2 PN)

Overview
The analog input is used to acquire external analog signals. These signals can be voltages or
currents, for example. Analog inputs are used, for example, to be able to enter a speed or torque
as analog signal.
Making basic settings
Proceed as follows to make the basic settings for the analog input:
1. Select the basic configuration of the input signal for the analog input:
– [0] voltage input unipolar (0 V to +10 V
– [2] current input unipolar (0 mA to +20 mA)
– [3] current input unipolar monitored (4 mA to +20 mA)
– [4] voltage input bipolar (-10 V to +10 V
– [5] current input unipolar (-20 mA to +20 mA)
2. Select the offset value for the analog input.
The offset value is added to the input signal before the scaling characteristic.
Configure scaling of the analog input
The scaling is used to adapt to the machine or to the existing components. For example, even
when the complete input range of the voltage or the current is not utilized, the input value can
still be scaled to 100 %.
