Braking resistor Siemens SINAMICS – 6SL3201-0BE21-0AA0
Braking resistor for PM240‑2 Power Modules, frame size FSD
Braking resistor for PM240‑2 Power Modules, frame size FSG
Excess energy in the DC link is dissipated in the braking resistor. The braking resistors are intended for use with PM240‑2 Power Modules which feature an integrated braking chopper, but cannot regenerate energy to the supply system. 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 installed laterally next to the PM240‑2 Power Modules. The braking resistors for the Power Modules, frame sizes FSD to FSG, 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 therefore reduced.
Every braking resistor has a temperature switch (UL-listed). The temperature switch should be evaluated to prevent consequential damage if the braking resistor overheats.
A PM250 Power Module is capable of line-commutated energy feedback. A braking resistor cannot be connected and is not necessary.
For the electromagnetically compatible connection of an optionally connectable braking resistor, the corresponding shield connection kit is to be ordered for frame sizes FSD to FSG.
For more information, see Shield connection kits in the section Supplementary system components.
