 Sets the Low Voltage (Lv) level. When the DC BUS voltage is lower than Pr. 06-00, the drive
stops output and the motor free runs to a stop.
 If the Lv fault is triggered during operation, the drive stops output and the motor free runs to a
stop. There are three Lv faults: LvA (Lv during acceleration), Lvd (Lv during deceleration), and
Lvn (Lv in constant speed) that are triggered according to the status of acceleration or
deceleration. You must press RESET to clear the Lv fault. The drive automatically restarts if you
set to restart after momentary power loss (refer to Pr.07-06 Restart after Momentary Power Loss
and Pr.07-07 Allowed Power Loss Duration for details).
 If the Lv fault is triggered when the drive is in STOP status, the drive displays LvS (Lv during stop),
which is not recorded, and the drive restarts automatically when the input voltage is higher than
Pr. 06-00 + Lv return level (as listed below).
