0: Disabled
1: Enbl with Timer
2: Enbl whl CPU act
0: Disabled. Regenerative unit trips on Uv1 fault when
power is lost.
1: Recover within the time set in L2-02. Uv1 will be
detected if power loss is longer than L2-02.
2: Recover as long as CPU has power. Uv1 is not detected.
Note:
Even if L2-01 is set to 1 or 2, the regenerative unit
may detect a fault when momentary-power-loss occurs
during regeneration or during no load.
Default: 0
Min.: 0
