Behaviour of SINAMICS converters during supply voltage variations and dips

Supply voltage ranges
SINAMICS units are dimensioned for relatively wide supply voltage ranges, whereby each range covers several of
the worldwide nominal supply voltages V
The converter Chassis units SINAMICS G130 and the converter cabinet units SINAMICS G150 are available in three
supply voltage ranges. The components of the modular system SINAMICS S120 (Chassis and Cabinet Modules) as
well as converter cabinet units SINAMICS S150 are available in two supply voltage ranges. The supply voltage range
of the units has to be selected so that the on-site nominal supply voltage V
range.

Hardware set-up:

Firmware set-up:
These settings are absolutely essential, in order that the units behave optimally during supply voltage variations. On
the one hand, they ensure that the units are as insusceptible as possible to supply voltage variations and that
unnecessary fault trips are avoided. On the other hand, they also ensure that the units react to unacceptably large
supply voltage changes with prompt fault trips, thus avoiding any damage being incurred to the units.
The hardware settings also guarantee a sufficient level for the 230 V produced by the transformers for the auxiliaries
and the fans at lower supply voltage and prevent the overloading of the 230 V auxiliaries when the supply voltage is
increased.
The firmware settings ensure an optimal adaptation of the under and over-voltage trip levels of the DC link voltage.
For all further considerations, it is assumed that the units are set-up correctly in terms of hardware and firmware,
accordning to the on-site available nominal supply voltage V
Continuously permissible supply voltage variations
Continuous operation of SINAMICS units is permissible in the following range of the nominal supply voltage:
In this supply voltage range, all the auxiliaries supplied with 230 V by the internal transformer operate within their
permissible limits and also the fans supplied with 230 V by an internal transformer are able to fully provide the cooling
air flow required by the power components within the limits of the permissible frequency tolerances. The DC link
voltage has a wide safety margin to the under and over-voltage trip level regardless of whether a regulated rectifier
(Active Infeed) or unregulated rectifier (Basic Infeed or Smart Infeed) is used.
