Analog input as setpoint source

Interconnecting an analog input
If you have selected a pre-assignment without a function of the analog input, then you must
interconnect the parameter of the main setpoint with an analog input.

Table 8- 1
Parameter
p1070 = 755[0]
p1075 = 755[0]
You must adapt the analog input to the connected signal, e.g. ± 10 V or 4 ... 20 mA. You will
find additional information in the section: Analog inputs (Page 81).
