[Bus Reg Mode A]
[Bus Reg Mode B]
Sets the method and sequence of the DC bus regulator voltage. Choices
are dynamic brake, frequency adjust, or both. Sequence is determined by
programming or digital input to the terminal block.
Dynamic Brake Setup
If a dynamic brake resistor is connected to the drive, both of these
parameters must be set to either option 2, 3 or 4.
Refer to the Attention statement on page P-3

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 a protective circuit must be supplied.
