Unit groups
Each parameter that can be switched is assigned to a unit group which can be switched
within certain limits depending on the group.
This assignment and the units groups for each parameter appear in the parameter list in the
SINAMICS List Manual.
The unit groups can be individually switched using 4 parameters (p0100, p0349, p0505 and
p0595).

9.3.14 Derating behavior at increased pulse frequency
Description
To reduce motor noise or to increase output frequency, the pulse frequency can be
increased relative to the factory setting.
The increase in the pulse frequency normally results in a reduction of the maximum output
current (see "Technical data/current derating depending on the pulse frequency").
When commissioning the converter the behavior at overload is adjusted in such a manner
that the pulse frequency is variably reduced so that the required power can be obtained.
