Protective functions during installation

When a brake resistor is installed, the best

possible endeavors should be made to avoid

overloads, as the heat generating from a brake

resistor may involve a fire risk.

NB!:

The brake resistor should be fitted to a

nonflammable material.

For protection of the installation, a thermal relay

should be fitted that cuts off the frequency converter

if the brake current becomes too high. Flat

pack resistors are self-protecting.

Calculate the brake current setting of the

thermal relay as follows:

Itherm relay =

is the current brake resistor value calculated in

the section on "Calculation of brake resistance". The

figure shows an installation with a thermal relay.

The brake current setting of thermal relay for Danfoss

40% brakeresistors can be found in the table further on.

Some of the Danfoss Brakeresistors contain a thermal

switch (see table further on). This switch is NC

(normally closed) and can be used e.g. coasting stop

reverse between terminal 12 and 27. The drive will

then coast, if the thermal switch is opened.

NB!:

The thermal switch is not a protective

device. For protection, use a thermal

switch as shown in the figure.
