L2-04: Powloss Ramp Time@recovery

L2-04
(0488)
Powloss Ramp
Time@recovery
Sets the time for the drive output voltage to go back to correct voltage after completing speed
searches.
Determined by o2-04, C6-
01
(0.0 - 5.0 s)
Sets the time for voltage to recover from 0 V to the value set in
E1-05 [Max Output Voltage]
.

L2-05: UV Detection Lvl (Uv1)
No.
(Hex.)
Name
Description
Default
(Range)
L2-05
(0489)
UV Detection Lvl (Uv1)
Sets the voltage at which a
Uv1 [DC Bus Undervoltage]
fault is triggered or at which the KEB
function is activated. Usually it is not necessary to change this setting.
Determined by o2-04 and
E1-01
(200 V Class: 150 - 210 V,
400 V Class: 300 - 420 V)
NOTICE:
Damage to Equipment. When you set this parameter to a value lower than the default, you must install an AC reactor
on the input side of the power supply. If you do not install an AC reactor, it will cause damage to the drive circuitry.
Note:
If the low voltage detection level is near the lower limit value of
L2-05
, the drive will detect
Uv1
during KEB Ride-Thru operation. Do
not set the value too low when you use the KEB Ride-Thru function.

L2-06: KEB Decel Time

Expert
KEB Decel Time
Sets the deceleration time during KEB operation used to decrease the maximum output frequency
to 0.
0.0 s
(0.0 - 6000.0 s)
Set
L2-29 = 3 or 4 [KEB Method = System KEB1 Ride-Thru or System KEB2 Ride-Thru]
to enable this function.
When
L2-29 = 2 , 3, 4 [Single KEB2 Ride-Thru, System KEB1 Ride-Thru, System KEB2 Ride-Thru]
and you do
KEB Auto-Tuning, the drive will automatically set this value.
Sets the deceleration time necessary to decelerate from the frequency reference to 0 Hz when the drive detects a
momentary power loss. If a
Uv1 [DC Bus Undervoltage]
fault occurs during KEB operation, decrease the
deceleration time. If an
ov [Overvoltage]
fault occurs, increase the deceleration time.
•
L2-06 = 0
The drive automatically decreases
C1-09 [Fast Stop Time]
to the base value to keep the DC bus voltage above
the low voltage detection level. The drive ignores
L2-02 [RideThrough Time@Power Loss]
in this condition.
•
L2-06 ≠ 0
As shown in
, the frequency reference decelerates to the KEB frequency level as specified by the
deceleration rate set in
L2-06
and then returns to the initial frequency reference as specified by
C1-01 [Accel
Time 1]
. The drive uses the setting value of the KEB frequency rate as shown in the this formula to set the KEB
frequency level:
KEB frequency level = Output frequency before power loss × (1 -

(L2-06)
