GV6000 AC Drive User Manual
When using the braking resistor connections, DB Resistor Type (163) must be set to
one of the following selections:
0 = Internal: Refers to DB plate-style resistor options kits that can be mounted
directly to the heatsink chassis of the drive.
1 = External: Refers to externally-mounted resistors. These could be panel, cage,
or other type of mounting, and are not specifically designed by Rockwell Automation
to mount directly to the GV6000 AC drive.
!
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 5.4, or an
equivalent, must be supplied.
ATTENTION: Equipment damage may result if a drive-mounted
(internal) resistor is installed and DB Resistor Type (163) is set to 1
(External Res). Thermal protection for the internal resistor will be
disabled, resulting in possible device damage
