Figure 6-27 Example: Analog input 0 as setpoint source
In the quick commissioning, you define the preassignment for the converter interfaces.
Depending on what has been preassigned, after quick commissioning, the analog input can be
interconnected with the main setpoint.
Example
Setting with analog input 0 as setpoint source:
Parameter Description
p1070 = 755[0] Interconnects main setpoint with analog input 0
p1075 = 755[0] Interconnects supplementary setpoint with analog input 0
Parameters
