163 [DB Resistor Type]
Selects whether the internal or an
external DB resistor will be used.
If a dynamic brake resistor is connected to
the drive, [Bus Reg Mode x], A, B or Both
(if used), must be set to either option 2, 3
or 4.

166 [Flux Braking]
Set to use an increase in the motor flux
current to increase the motor losses, and
allow a faster deceleration time when a
chopper brake or regenerative capability
is not available. Can be used as a
stopping or fast deceleration method.

ATTENTION: The drive does not offer protection for externally
mounted brake resistors. A risk of fire exists if external braking
resistors are not protected. External resistor packages must be
self-protected from over temperature or the protective circuit shown
in
Figure C.1 on page C-1 , or equivalent, must be supplied.
ATTENTION: Equipment damage may result if a drive mounted
(internal) resistor is installed and this parameter is set to “External
Res.” Thermal protection for the internal resistor will be disabled,
resulting in possible device damage.
