● Sets the number of poles for the motor (must be an even number).
● Set up Pr.01-63 and Pr.05-72 before setting up Pr.05-73 to make sure the motor operates normally.

● Sets the Low Voltage (LV) level. When the DC bus voltage is lower than Pr.06-00, a LV fault is triggered, and
the drive stops output then the motor coasts to a stop.
● If the LV fault is triggered during operation, the drive stops output and the motor coasts 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 set to restart after momentary power loss (see 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 the LV level of 30V
(230V series), 60V (460V series) or 75V (575V series).
