[Bus Reg Mode A]
[Bus Reg Mode B]
Active bus regulation mode. Choices are
dynamic brake, frequency adjust or both.
Sequence is determined by programmed value
or digital input programmed for “Bus Reg Md
B.”
Dynamic Brake Setup
If a dynamic brake resistor is connected to the
drive, both these parameters must be set to
either option 2, 3 or 4.
Refer to the Attention statement on page 10 for
important information on bus regulation.

mounted brake resistors. A risk of fire exists if external braking
resistors are not protected. External resistor packages must be

ATTENTION: Equipment damage can result if a drive mounted
(internal) resistor is installed and this parameter is set to
“External Res.” Thermal protection for the internal resistor is
disabled, resulting in possible device damage.
