Rockwell Automation Liqui-Flo DBT Reach Drive - Manual (Page 120)

3-94 DBT Reach Drive User Manual
The drive will not jog while running or while the Stop-Clear Faults input is open. Start
has precedence over jog.
If one of these input functions is configured and the other one is not, table 3.7 still
applies, but the unconfigured input function should be considered permanently open.
13 = Stop Mode B: This digital input selects between two different drive stop modes.
If the input is open, then Stop Mode A selects which stop mode to use. If the input is
closed, the Stop Mode B selects which stop mode to use. If this input function is not
configured, then Stop Mode A selects which stop mode to use.
14 = Bus Regulation Mode B: This digital input function selects how the drive will
regulate excess voltage on the DC bus.
If the input is open, then Bus Reg Mode A selects which bus regulation mode to use. If
the input is closed, then Bus Reg Mode B selects which bus regulation mode to use. If
this input function is not configured, then Bus Reg Mode A selects which bus
regulation mode to use.
15-17 = Speed Select 1, 2, 3: One, two, or three digital input functions can be used to
select the speed reference used by the drive, and they are called the Speed Select
input functions. The current open/closed state of all Speed Select input functions
combine to select which source is the current speed reference.
There are 7 possible combinations of open/closed states for the three input functions,
and thus 7 possible parameters can be selected. The 7 parameters are: Speed Ref A
Sel and Preset Speed 2 through Preset Speed 7.
If the Speed Select input functions select Speed Ref A Sel, then the value of that
parameter further selects a reference source. There are a large number of possible
selections, including all 6 presets.
If the input functions directly select one of the preset speed parameters, then the
parameter contains a frequency that is to be used as the reference.

!
ATTENTION: If a normal drive start command is received while the drive
is jogging, the drive will switch from jog mode to run mode. The drive will
not stop, but may change speed and/or change direction. Failure to
observe this precaution could result in severe bodily injury or loss of life.
