Overview of important parameters (see SINAMICS S120/S150 List Manual)
● p0341[0...n] motor moment of inertia
● p0342[0...n] ratio between the total moment of inertia and that of the motor
● p1455[0...n] CI: Speed controller P gain adaptation signal
● r1493 CO: Moment of inertia, total
● p1496[0...n] acceleration pre-control scaling
● p1497[0...n] CI: Moment of inertia scaling
● p1498[0...n] load moment of inertia
● p1551[0...n] BI: Torque limit, variable/fixed signal source

Control Units without infeed control

To ensure that the drive line-up functions satisfactorily, you must ensure – among other
things – that the drives only draw power from the DC link when the infeed is in operation. In a
DC link line-up that is controlled by precisely one Control Unit and which includes a drive
object X_INF
during commissioning.
In the following cases, the BICO input p0864 must be supplied manually:
● Smart Line Modules without DRIVE-CLiQ (5 kW and 10 kW)
● DC link line-up with more than one Control Unit
Examples: interconnecting "Infeed ready"
Smart Line Modules without DRIVE-CLiQ (5 kW and 10 kW)
