Siemens SINAMICS G115D

Principle of operation
The DC link voltage increases as soon as the motor supplies regenerative power to the converter
when braking. Depending on the DC link voltage, the converter outputs the regenerative power
to the integrated or optional braking resistor. The braking resistor converts the regenerative
power into heat, therefore preventing DC link voltages > Vdc_max.
