[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 these parameters must
be set to either option 2, 3 or 4.
Refer to the Attention statement on page

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. See the PowerFlex 70 User Manual for more information.
