Fixed Setpoints - Siemens SINAMICS S120 Function Manual

Extended setpoint channel

4.2 Fixed setpoints

4.2 Fixed setpoints
Function description
The "Fixed setpoints" function can be used to specify preset speed setpoints. These fixed
setpoints are defined using parameters and selected via binector inputs. Both the individual
fixed setpoints and the effective fixed setpoint are available for further interconnection via a
connector output (e.g. to connector input p1070 - CI: Main setpoint).
Features
The function is characterized by the following features:
● Number of fixed setpoints: Fixed setpoint 1 to 15
● Selection of fixed setpoints: Binector input bits 0 to 3
– Binector input bits 0, 1, 2 and 3 = 0 → setpoint = 0 active
– Unused binector inputs have the same effect as a "0" signal
Parameterizing the function (STARTER)
In the STARTER commissioning tool, the "Fixed setpoints" parameterizing screen form in the
project navigator under the relevant drive is called by double-clicking "Setpoint channel" >
"Fixed setpoints".
