L2-01: Momentary Power Loss Operation Selection
When a momentary power loss occurs (DC bus voltage falls below the level set in L2-05), the drive can automatically return
to the operation it was performing prior to the power loss based on certain conditions.
No. Name Setting Range Default
L2-01 Momentary Power Loss Operation Selection 0 to 5 0
Setting 0: Disabled (default)
If power is not restored within 15 ms, a Uv1 fault will result and the motor coasts to stop.
Setting 1: Recover within L2-02
When a momentary power loss occurs, the drive output will be shut off. If the power returns within the time set to parameter
L2-02, the drive will perform Speed Search and attempt to resume operation. If the power does not return within this time, it
will trigger a Uv1 fault.
