SP600 AC Drive User Manual
Selects whether the internal or an external DB resistor option will be
used. The internal resistor is the SP600-specific DB option that
mounts internally to the drive’s frame. An external DB resistor is
panel-mounted separately from the drive. If a dynamic brake
resistor is connected to the drive, Bus Reg Mode A & B must be set
to option 2, 3, or 4.

ATTENTION: AC drives do not offer protection for
externally mounted braking resistors. A risk of fire
exists if external braking resistors are not protected.
External resistor packages must be self-protected
from overtemperature, or the protective circuit
shown in figure 12.24, or an equivalent, must be
supplied.
ATTENTION: Equipment damage may result if a
drive-mounted (internal) resistor is installed and
parameter 163 is set to 1 (External Res). Thermal
protection for the internal resistor will be disabled,
resulting in possible device damage.
