When
L2-29 = 1 [KEB Method = Single KEB1 Ride-Thru]
and you do KEB Auto-Tuning, the drive will automatically set
C1-09
. If
you must not change the Fast Stop time, do not do KEB Tuning.
*2
If you do KEB Tuning when
L2-29 = 2, 3, or 4 [KEB Method = Single KEB2 Ride-Thru, System KEB1 Ride-Thru, or System KEB2
Ride-Thru]
, the drive will automatically set
L2-06 [KEB Decel Time]
.

The drive sets this value automatically when KEB Tuning completes correctly.

L2-01: RideThru@PwrLoss
No.
(Hex.)
Name
Description
Default
(Range)
L2-01
(0485)
RideThru@PwrLoss
Sets the drive operation after a momentary power loss.
0
(0, 1)
The drive detects momentary power loss when the drive DC bus voltage is less than the value set in
L2-05 [UV
Detection Lvl (Uv1)]
.
0 : Disabled
1 : Enabled
This mode is defined using
L2-50 [RidThruMode@PwrLoss]
.
Note:
When you set
L2-01 and L2-50
, make sure that you know these items:
•
You can use a Momentary Power Loss Unit on models 2001 to 2042 and 4001 to 4023 for a longer momentary power loss ride through
time. A Momentary Power Loss Unit makes it possible to continue operation of the drive after a maximum of 2 seconds of power loss.
•
When you set
L2-01 = 1 and L2-50 = 0 to 3
, keep the magnetic contactor on the drive input side ON and keep the control signal while
the drive does KEB operation.
•
When
L2-01 = 1 and L2-50 = 1 to 4
,
Uv [DC Bus Undervoltage]
will flash on the keypad while the drive is attempting to recover from
a momentary power loss. The drive will not output a fault signal at this time.
•
When you use a magnetic contactor between the motor and the drive, keep the magnetic contactor closed while the drive does KEB
operation or tries to restart with Speed Search.
•
Keep the Run command active during KEB operation. The drive cannot accelerate back to the frequency reference when the power
returns.
•
When
L2-01 = 1 and L2-50 = 2 to 4
, if the control power supply voltage is less than the CPU operation level during KEB Ride-Thru, it
will trigger
Uv1
.
■
L2-02: RideThrough Time@Power Loss
No.
(Hex.)
Name
Description
Default
(Range)
L2-02
(0486)
RideThrough Time@Power
Loss
Sets the maximum time that the drive will wait until trying to restart after power loss.
Determined by o2-04, C6-
01
(0.0 - 25.5 s)
This function is applicable when
L2-01 = 1 [RideThru@PwrLoss = Enabled] and L2-50 = 0, 2
[RidThruMode@PwrLoss = Timer Controlled, KEB Mode]
. If power loss operation is longer than the time set in
this parameter, the drive will detect
Uv1 [DC Bus Undervoltage]
, turn OFF output, and the motor will coast to
stop.
Note:
•
The length of time that the drive can recover after a power loss changes when drive capacity changes.
•
The upper limit of the possible momentary power loss Ride-Thru time changes when drive capacity changes.

L2-03: Min Baseblck Time
No.
(Hex.)

Description

L2-03
(0487)
Min Baseblck Time
Sets the minimum time to continue the drive output block (baseblock) after a baseblock.
Determined by o2-04, C6-
01
(0.1 - 5.0 s)
Sets the length of time that the drive will wait for the residual voltage in the motor to dissipate in estimation to the
secondary circuit time constant of the motor. If
oC [Overcurrent]
or
ov [DC Bus Overvoltage]
occur at the start of
Speed Search, after power returns, or during DC Injection Braking, increase this setting.
