L 2 - 0 1 : Momentary Power Loss Ride-thru
Protection
The setting of this parameter either enables or disables the ride-thru feature of the
drive. If disabled, the unit will stop immediately whenever a power loss occurs. If enabled,
the drive will continue to operate during a momentary power loss of up to 80%, but if the
loss exceeds the identified time period, the drive will stop.
L 2 - 0 2 : Power Loss Ride-Thru
Deactivation Time
If the loss exceeds the length of time identified by L 2 - 0 2 , the drive will stop. The
factory setting of this parameter, in 0.1 second increments, is related to the drive's
capacity rating (see Appendix 3).
Note that the RUN command must be maintained throughout the ride-thru period. If
L 2 - 0 1 is set to " 2 ", a " U V " alarm is displayed during power loss, and no fault signal is
output at any multi-function output that is programmed for a fault.
