Parameter Descriptions 12-43
This DC braking voltage is removed by the following events:
• Opening an Enable digital input
• Reissuing the Start command
• DC brake time expiring
Caution must be used when setting DC Brake Level. Excess motor
current could damage the motor. Caution must also be observed
since motor voltage will exist even while stopped.
Selects the source for DC Brake Level (158). You can also select
the amount of time that braking will be applied (159), as well as
magnitude of current (158). This mode of braking will generate up to
40% of the rated motor torque for braking. It is typically used for low
inertia loads.
Sets the DC braking current level used for the DC injection braking
mode (parameter 155 = 3).
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.

ATTENTION: If a hazard of injury due to movement
of equipment or material exists, an auxiliary
mechanical braking device must be used to stop the
motor. Failure to observe this precaution could result
in severe bodily injury or loss of life.
ATTENTION: This feature should not be used with
synchronous or permanent magnet motors. Motors
may be demagnetized during braking. Failure to
observe this precaution could result in damage to,
or destruction of, the equipment.
