■
Overview
Excess energy in the DC link is dissipated via the braking resis-
tor.
The braking resistor is connected to a Braking Module. The
braking resistor is positioned outside the cabinet or switchgear
room. This enables the resulting heat loss around the Power
Modules to be dissipated. This reduces the level of air condition-
ing required.
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 factor.
A temperature switch (NC contact) is also fitted. This responds
when the maximum permissible temperature is exceeded and
can be evaluated by a controller. The maximum permissible ca-
ble length between the Braking Module and braking resistor is
100 m.
Information about possible duty cycles of the braking resistors
as well as other configuration information is contained in the
SINAMICS Low Voltage Engineering Manual.
