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.
3: KEB Mode 3: KEB deceleration for the time set to L2-02.
4: KEB Stop Mode 4: KEB deceleration as long as CPU has power.
5: KEB Decel to Stop 5: KEB deceleration to stop.
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
