Overview
Braking resistor
Excess energy in the DC link is dissipated via the braking
resistor.
The corresponding braking resistor is connected to a Braking
Module or Basic Line Module. Positioning the braking resistor
outside the control cabinet or switchgear room enables the
resulting thermal losses to be routed away. This reduces the
level of air conditioning required.
