Regenerative operation is possible with converters if an external
braking resistor is connected. The regenerative energy is converted to
heat in the braking resistor. The braking resistor should be mounted
outside the control cubicle in order to avoid the electronic components
in the cubicle becoming overheated.
To protect the brake chopper against an overload of current, the
smallest permissible resistance value of the braking resistor must not
be fallen short of. The control electronic system monitors the pulse duty
factor of the brake chopper and switches it off in the event of an
overload.
Length of the connecting cable between the converter and the external
braking resistor < 15 m.
