What is the usega of brking resistor? and how it will
useful to Drive...?
Answer Posted / vinod
when a load is to be breaked suddenly with a less
decelaration time or when a motor is stoped within its
system time constnt,they regenerate the energy back to the
mains.this regeneration happens through VFD.
to dissipate this regenerated energy a breaking resistor is
connected to the VFD.
