Rockwell Automation Liqui-Flo AC GP Vector Drive Version 6.4 - Manual (Page 162)

4-80 LiquiFlo AC Drive, Software Reference Version 6.4
If this feature is enabled and DC bus voltage drops below 80% of nominal, the drive
decelerates the motor enough to maintain bus voltage. Alarm code LIL appears on the
display while the drive is regulating the DC bus. Note that the lighter the load, the
longer the power dip ride-through time can be. When input power is restored, the drive
ramps to the reference speed.
If this feature is enabled, and the DC bus voltage drops while the drive is stopped, LIL
will be displayed.

U.022 Motor Nameplate Horsepower
This parameter
identifies the motor
horsepower as it
appears on the motor
nameplate. Parameter Range: 0.3 to 2000.0 HP
Default Setting: Power Module-dependent, see Appendix C
Parameter Type: Configurable
Refer also to parameters: U.002 Motor Poles
U.003 Motor Nameplate Base Frequency
U.004 Motor Nameplate Amps
U.005 Motor Nameplate RPM
U.006 Magnetizing Current
U.007 Motor Nameplate Volts
U.023 Low DC Bus Fault Avoidance Enable
This parameter
selects how the drive
responds to power
loss (line dip
condition).
This feature applies
to SVC applications
only and is not
available if the drive
is configured as a
torque regulator.
Parameter Range: OFF = Drive will not regulate the DC bus on a line
dip condition
ON = Drive will decelerate the motor to attempt to
hold up the DC bus on a line dip condition
Default Setting: OFF
Parameter Type: Tunable
