SINAMICS G130
Drive converter chassis units
75 kW to 800 kW
Overload capability
The SINAMICS G130 converters have an overload reserve in or-
der to overcome breakaway torques, for example. If larger surge
loads occur, this must be taken into account in the configuration.
For drives with overload requirements, the appropriate base
load current must, therefore, be used as a basis for the required
load.
The criterion for overload is that the drive is operated with its
base load current before and after the overload occurs on the
basis of a duty cycle duration of 300 s.
The base load current for a low overload
I
L
is based on a duty
cycle of 110% for 60 s or 150% for 10 s.
The base load current for a high overload
I
H
is based on a duty
cycle of 150% for 60 s or 160% for 10 s.
