507 DC-BRAKING CURRENT 234567 (2.4.8)
Gives the current that is fed into the motor during DC braking. DC-brake in stop state will
only use a tenth of this parameter value.
This parameter is used together with parameter ID516 to decrease the time before the motor
is able to produce maximum torque at start-up.
508 DC-BRAKING TIME AT STOP 234567 (2.4.9)
Determines if braking is ON or OFF and the braking time of the DC-brake when the motor is
stopping. The function of the DC-brake depends on the stop function, parameter ID506.

Selection name
The motor coasts to a halt without any control from the AC
drive, after the Stop command.
After the Stop command, the speed of the motor is deceler-
ated according to the set deceleration parameters to zero
speed.
If the regenerated energy is high it may be necessary to use
an external braking resistor to stop within the set decelera-
tion time.
After the Stop command, the speed of the motor is deceler-
ated according to the set deceleration parameters. However,
when Run Enable is selected, the motor coasts to a halt with-
out any control from the AC drive.
The motor coasts to a halt without any control from the AC
drive. However, when Run Enable signal is selected, the
speed of the motor is decelerated according to the set decel-
eration parameters. If the regenerated energy is high it may
be necessary to use an external braking resistor for faster
deceleration.
