  Excess energy in the DC link is dissipated via the braking resistor.

  The braking resistor is connected to a Braking Module.

  By positioning the braking resistor outside the cabinet or switchgear room, it is possible to extract the heat losses away from the Line Modules / Motor Modules. This reduces the level of air conditioning required.

  The maximum permissible cable length between the Braking Module and braking resistor is 100 m (328 ft).

  Two braking resistors with different rated and peak power values are available for the devices.

  The braking resistor is monitored on the basis of the duty cycle. A temperature switch (NC contact) is also fitted. This responds when the maximum permissible temperature is exceeded and can be evaluated by a controller.

  Information about possible duty cycles of the braking resistors and other notes are included in the SINAMICS Low Voltage Engineering Manual.
