It

is

used

to

dissipate

the

power

regenerated

by

the

motor

during

rapid

deceleration

or

during

overhauling

load

conditions.

The

regenerated

energy

is

normally

consumed,

as

shown

in

figure

1,

by

mechanical

loss,

by

themotor,

and

by

the

drive.

The

remaining

energy

is

stored

in

the

drive's

DC

bus

capacitor.

If

the

remaining

energy

causes

the

capacitor

voltage

to

rise

above

the

normal

operating

range,

the

Braking

Unit

will

discharge

the
