L2: Momentary Power Loss
Use L2 parameters to configure drive functions for momentary power loss conditions.

Momentary Power
Loss Operation
Selection
Enables and disables the momentary power loss
function.
0: Disabled - Drive trips on (UV1) fault when
power is lost.
1: Power Loss Ride-Thru Time - Drive will
restart if power returns within the time set in
L2-02.
2: CPU Power Active - Drive will restart if
power returns as long as the CPU is working.

For a restart to occur, the run
command must be maintained
throughout the ride-thru
period.

Loss Ride-Thru Time
Sets the Power Loss Ride-Thru time. Only
effective when L2-01 = 1.

Momentary Power
Loss Minimum
Baseblock Time
Sets the minimum wait time for residual motor
voltage decay before the drive output
reenergizes after power loss ride-thru. If L2-03
is greater than L2-02, operation resumes after
the time set in L2-03.

Undervoltage
Detection Level (UV)
Sets the DC Bus undervoltage trip level. If this
is set lower than the default setting, additional
AC input impedance or DC bus reactance may
be necessary.
This value is used for KEB activation if L2-01
> 0.
