<1> Default setting is dependent on parameter o2-04, Drive Model Selection.
<2> Default setting is dependent on parameter E1-01, Input voltage Setting.
<3> Values shown are specific to 200 V class drives. Double the value for 400 V class drives.
<4> Setting range value is dependent on parameter C1-10, Accel/Decel Time Setting Units. When C1-10 = 0 (units of 0.01 seconds), the setting range
becomes 0.00 to 600.00 seconds.

PwrL Selection 0: Disabled. Drive trips on Uv1 fault when power is lost.
0: Disabled 1: Recover within the time set in L2-02. Uv1 will be detected if
1: Enbl with Timer power loss is longer than L2-02.
2: Enbl whl CPU act 2: Recover as long as CPU has power. Uv1 is not detected.
Sets the Power Loss Ride-Thru time. Enabled only when
L2-01 = 1 or 3.
PwrL Ridethru t
Sets the minimum wait time for residual motor voltage decay
before the drive output reenergizes after performing Power Loss
Ride-Thru.
PwrL Baseblock t
Increasing the time set to L2-03 may help if overcurrent or
overvoltage occur during Speed Search or during DC Injection
Braking.
Sets the time for the output voltage to return to the preset V/f
pattern during Speed Search.
PwrL V/F Ramp t
Sets the DC bus undervoltage trip level.
PUV Det Level
Sets the time required to decelerate from the speed when KEB
was activated to zero speed.
KEB Decel Time
Sets the time to accelerate to the frequency reference when
momentary power loss is over. If set to 0.0, the active
KEB Accel Time
acceleration time is used.
Sets the percentage of output frequency reduction at the
beginning of deceleration when the KEB Ride-Thru function is
KEB Freq Red
started.
Reduction = (slip frequency before KEB) × L2-08 × 2
Sets the desired value of the DC bus voltage during KEB
Ride-Thru.

0: Disabled.
StallP Accel Sel
1: General purpose. Acceleration is paused as long as the current
0: Disabled
is above the L3-02 setting.
1: General purpose
2: Intelligent. Accelerate in the shortest possible time without
2: Intelligent
exceeding the L3-02 level.
Used when L3-01 = 1 or 2. 100% is equal to the drive rated
current.
StallP Accel Lvl
Sets Stall Prevention lower limit during acceleration when
StallPAcc LowLim operating in the constant power range. Set as a percentage of
drive rated current.
