Rockwell Automation Liqui-Flo DBT Reach Drive - Manual (Page 123)

Parameter Descriptions 3-97
If the physical input is closed, this indicates that the drive is connected to common DC
bus and normal precharge handling can occur, and that the drive can run (start
permissive). If the physical input is open, this indicates that the drive is disconnected
from the common DC bus, and thus the drive should enter the precharge state
(precharge relay open) and initiate a coast stop immediately in order to prepare for
reconnection to the bus.
If this input function is not configured, then the drive assumes that it is always
connected to the DC bus, and no special precharge handling will be done.
31-33 = Spd/Trq Sel#: See Table 11.5.
35 = PI Invert: Inverts the sign of the PI Error Value.
36 = Torque Setpt1: Selects Torque Setpt1 for Torque Ref A Sel when set. If Torque
Setpt1 is not set, the value selected in Torque Ref A Sel is used.
37 = Micro Pos: Microposition Input. When closed, command frequency is set to a
percentage speed reference as defined in MicroPosScale% (611).
38 = Fast Stop: When closed, drive will stop with a 0.1 second decel time. If Torque
Proving is in use, float will be ignored at end of ramp and the mechanical brake will be
set.
39 = Decel Limit: Reference changed to preset speed 1 when activated.
40 = End Limit: Enables a fast stop to zero speed using a zero decel time.
41-42 = UserSet Sel#: 0 = Disabled; 1 = Enabled
43-45 = Run Level, RunFwd Level, RunRev Level: Provides a run level input. They
do not require a transition for enable or fault, but a transition is still required for a stop.

ATTENTION: Changing parameter 89 to Terminal Blk or Network
while Start At PowerUp is enabled may start the drive if a start
command is on from the newly selected logic source.
When Start At PowerUp is enabled, the user must ensure that
automatic start up of the driven equipment will not cause injury to
operating personnel or damage to the driven equipment. In addition,
the user is responsible for providing suitable audible or visual alarms or
other devices to indicate that this function is enabled and the drive may
start at any moment. Failure to observe this precaution could result in
severe bodily injury or loss of life.
ATTENTION: Removing and replacing the LCD HIM while the drive
is running may cause an abrupt speed change if the LCD HIM is the
selected reference source, but is not the selected control source. The
drive will ramp to the reference level provided by the HIM at the rate
specified in Accel Time 1 (140), Accel Time 2 (141), Decel Time 1
(142) and Decel Time 2 (143). Be aware that an abrupt speed change
may occur depending upon the new reference level and the rate
specified in these parameters. Failure to observe this precaution could
result in bodily injury.
