KEB DC Volt Setpoint
Sets the target value that controls the DC bus voltage to a constant level in Single Drive KEB
Ride-Thru 2. Sets the DC bus voltage level that completes the KEB operation for all other KEB
methods.

Set
L2-01 = 1 [RideThru@PwrLoss = Enabled]
, and
L2-50 = 2, 3, or 4 [RidThruMode@PwrLoss = KEB Mode,
KEB Stop Mode, KEB Decel to Stop]
or
KEB Ride-Thru 1/2 [H1-xx = 40, 41, 42, or 43]
, to enable the KEB
function.
1 : Single KEB1 Ride-Thru
The drive monitors the DC bus voltage and uses regenerative energy from the motor to hold the DC bus voltage at
the level set in
L2-11 [KEB DC Volt Setpoint]
.
The KEB operation continues and the deceleration rate changes as specified by
C1-09 [Fast Stop Time]
.
Note:
•
If the drive detects
Uv1 [DC Bus Undervoltage]
during KEB operation, decrease the value of
C1-09
.
•
If the drive detects
ov [Overvoltage]
during KEB operation, increase the value of
C1-09
.
2 : Single KEB2 Ride-Thru
The drive does KEB operation and automatically calculates the deceleration rate to make sure that the main circuit
electrical energy and main current voltage from motor regenerative energy is equal to
L2-11 [KEB DC Volt
Setpoint]
.
3 : System KEB1 Ride-Thru
The drive does not monitor the DC bus voltage and decelerates as specified by the KEB deceleration time set in
L2-06
.
Set
L2-06
to the time necessary to decelerate from the frequency reference to 0 Hz when the drive detects a
momentary power loss. The drive can decelerate and keep constant deceleration rates for more than one drive.
Note:
If you keep constant deceleration rates for more than one drive, it can trigger
ov
faults. Use the dynamic braking option with System
KEB Ride-Thru 1 to prevent
ov
faults.
4 : System KEB2 Ride-Thru
The drive monitors the DC bus voltage and decelerates for the deceleration time set in
L2-06
.
If the DC bus voltage increases, the drive momentarily holds the frequency to prevent
ov
while deceleration
continues.
Note:
When you cannot use a dynamic braking option, use System KEB Ride-Thru.

KEB ZeroSpeed Operation
Sets the operation when the output frequency decreases below the zero level (DC braking
injection starting frequency) during KEB deceleration when
L2-01 = 1 [RideThru@PwrLoss =
Enabled]
and
L2-50 = 2 to 4 [RidThruMode@PwrLoss = KEB ModeKEB Stop Mode, or KEB
Decel to Stop]
