  SINAMICS G110M braking resistors FSA and FSB

  Excess energy in the DC link is dissipated in the braking resistors in regenerative operation.

  The braking resistors are intended for use with SINAMICS G110M, which have an integrated braking chopper, but cannot regenerate energy to the line supply. For regenerative operation, e.g. the braking of a rotating mass with high moment of inertia, a braking resistor must be connected to convert the resulting energy into heat.

  The braking resistors can be mounted on the side of the Control Unit housing at the bottom. The heat from the braking resistor is dissipated over the Control Unit housing. Every braking resistor is equipped with thermal protection. The thermal protection prevents the braking resistor from being thermally overloaded.

  All braking resistors are provided as standard with a cable for connecting to the internal terminals.
