Derating factors
Motors whose maximum speeds exceed the following speeds must be operated with a
converter frequency of 8 kHz.
● 4-pole: 24000 rpm
● 6-pole: 16000 rpm
● 8-pole: 12000 rpm
Observe an appropriate Motor Module derating.
The rated motor current is the basis when selecting the Motor Module.
Note
The maximum speed can be increased under certain conditions. Contact your local
Siemens office.
You can configure the Motor Modules using the SIZER engineering tool.
● To achieve optimum operation, for the subsequently listed motors, set the following
data that deviates from the standard.
