Overview
Example: Braking resistors for Power Modules, frame sizes FSA and FSC
Example: Braking resistor for PM240 Power Modules frame size FSGX
Excess energy in the DC link is dissipated in the braking resistor.
The braking resistors are intended for use with PM240 Power
Modules which feature an integrated brake chopper, but cannot
regenerate energy to the supply system. There is an optional
plug-in Braking Module for frame size FSGX. For generator
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 installed at the side of the PM240
Power Modules. The braking resistors for the FSA and FSB frame
sizes are designed as base components. If the PM240 Power
Modules, frame size FSA or FSB, are operated without line reac-
tor, the braking resistors can also be installed under the Power
Modules.
The braking resistors for the Power Modules, frame sizes FSC to
FSGX, should be placed outside the control cabinet or outside
the switchgear room so that the heat is dissipated away from the
Power Modules. The level of air conditioning required is there-
fore reduced.
Every braking resistor has a temperature switch (UL-listed). The
temperature switch can be evaluated to prevent consequential
damage if the braking resistor overheats.
