162 [Bus Reg Mode A]
[Bus Reg Mode B]
Sets the method and sequence of the DC
bus voltage regulator. Choices are
dynamic brake, frequency adjust or both.
Options 2 & 3 only appear when a
dynamic brake is installed in the drive.
Dynamic Brake Setup
If a dynamic brake resistor is connected
to the drive, both of these parameters
must be set to either option 2 or 3.
Refer to the Attention statement on page
P-3 for important information on bus
regulation.

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 the protective circuit shown
in
Figure B.2 on page B-7 (or equivalent) must be supplied.

ATTENTION: Equipment damage and/or personal injury may result
if this parameter is used in an inappropriate application. Do not use
this function without considering applicable local, national and
international codes, standards, regulations or industry guidelines.
