[DB While Stopped]
Enables/disables dynamic brake
operation when drive is stopped. DB may
operate if input voltage becomes too
high.
Disabled = DB will only operate when
drive is running.
Enable = DB may operate whenever
drive is energized.

[DC Brake Level]
Defines the DC brake current level
injected into the motor when “DC Brake”
is selected as a stop mode. This also
sets the braking current level when “Fast
Stop” is selected.
The DC braking voltage used in this
function is created by a PWM algorithm
and may not generate the smooth
holding force needed for some
applications. Refer to the
PowerFlex
Reference Manual

ATTENTION:
If a hazard of injury due to movement of equipment
or material exists, an auxiliary mechanical braking device must be
used.
ATTENTION:
This feature should not be used with synchronous or
permanent magnet motors. Motors may be demagnetized during
braking.
