L1-13
Continuous
Electrothermal
Operation Selection
Determines whether or not to hold the
electrothermal value when the power supply is
interrupted.
0: Disabled
1: Enabled
0 to 1 1 A A A 46D 191
L2: Momentary Power Loss
Use L2 parameters to configure drive functions for momentary power loss conditions.
L2-01
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.
0 to 2 0 A A A 485
192
For a restart to occur, the run
command must be maintained
throughout the ride-thru
period.
L2-02
Momentary Power
Loss Ride-Thru Time
Sets the Power Loss Ride-Thru time. Only
effective when L2-01 = 1.
0.0 to
25.5
<12> A A A 486 193
L2-03
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.

Momentary Power
Loss Voltage
Recovery Ramp Time
Sets the time for the output voltage to return to
the preset V/f pattern during Speed Search.

5.0
<12> A A A 488 193
L2-05
<24>
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.

KEB Deceleration
Time
Sets the time required to decelerate from the
speed when KEB was activated to zero speed.

L2-07
KEB Acceleration
Time
Set the time to accelerate to the set speed after
recovery from a momentary power loss. If set to
0.0, the active acceleration time is used.

KEB Start Output
Frequency Reduction
Sets the percentage of output frequency
reduction at the beginning of deceleration when
the KEB function is started.
Reduction = (slip frequency before KEB) x L2-
