KEB StartV Offset Level
Sets the KEB start voltage offset.
Determined by A1-02
(200 V Class: 0 - 100 V,400
V Class: 0 - 200 V)
The drive uses this formula to calculate the KEB start voltage:
KEB start voltage =
L2-05 [UV Detection Lvl (Uv1)] + L2-31

RidThruMode@PwrLoss
Sets the drive operation after a momentary power loss..
0
(0 - 4)
0 : Timer Controlled
When power returns in the time set in
L2-02 [RideThrough Time@Power Loss]
, the drive will restart. If power
does not return in the time set in
L2-02
, the drive will detect
Uv1
.
The drive momentarily turns OFF its output after a power loss. If the power returns in the time set to
L2-02
, the
drive will do Speed Search and try to continue operation.
If the DC bus voltage is less than or equal to the
Uv1
detection level for the time set in
L2-02
, the drive will detect
Uv1
and output a fault signal.
Note:
•
The necessary time for the drive to restart after power returns is different for different drive capacities.
•
The upper limit of the possible momentary power loss Ride-Thru time is different for different drive models.
1 : While CPU Active
When power returns and the drive control circuit has power, the drive will restart. This will not trigger
Uv1
.
When there is a momentary power loss, the drive output will turn OFF. If the power returns and the drive control
circuit has power, the drive will do Speed Search and try to continue operation. This will not trigger
Uv1
. This
function lets the power loss be longer than when
L2-01 = 1
.
2 : KEB Mode
If power does not return in the time set in
L2-02
, the drive will detect
Uv1
.
When the drive detects momentary power loss, the drive will use regenerative energy from the motor through
KEB operation to decelerate. When you return power in the time set in
L2-02
, the drive will accelerate to the
frequency reference value that was used before the power loss. If you do not return power in the time set to
L2-02
,
the drive will detect
Uv1
and the drive output will turn OFF.
L2-29 [KEB Method]
sets the type of KEB operation.
3 : KEB Stop Mode
When power returns and the drive control circuit has power, the drive will restart.
The drive decelerates using regenerative energy from the motor until the power returns and then restarts when a
momentary power loss is detected. When power is restored during deceleration, the drive accelerates the motor
again to the frequency reference value used before the power loss. If the motor comes to a stop before the power
returns, the drive loses control power and the drive output shuts off. A
Uv1
is not triggered when power is restored
while power to the CPU in the drive is maintained. The type of KEB operation is determined by
L2-29
.
4 : KEB Decel to Stop
When power returns, the drive will continue to decelerate until the motor fully stops.
If the drive detects momentary power loss, the drive will use regenerative energy from the motor and ramp to
stop. When you return power to the drive, the drive will continue to decelerate until the motor comes to a full
stop. After you return power, the drive will ramp to stop in the set deceleration time.
L2-29
sets the type of KEB
operation.
