Analog Input As Setpoint Source; Specifying The Motor Speed Via The Fieldbus - Siemens SINAMICS G120 Original Instructions Manual

8.3.1

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.

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 98).
8.3.2

Specifying the motor speed via the fieldbus

If you enter the setpoint via a fieldbus, you must connect the converter to a higher-level
control. For further information, see Section Configuring the fieldbus (Page 107).
