The drive starts deceleration through KEB operation. The drive decelerates for the time set in parameter
L2-10
,
then it measures the DC bus voltage and the status of the digital input terminal set for KEB Ride-Thru. When the
DC bus voltage is less than the level set in
L2-11 [KEB DC Volt Setpoint]
, or if the KEB digital input is active,
KEB deceleration continues. When the DC bus voltage is more than the level set in
L2-11
, the drive ends KEB
operation. The drive accelerates the motor to the frequency reference value before the power loss, and usual
operation continues. If the time set in
L2-02
is expired, the drive detects
Uv1
. When you cancel the KEB Ride-
Thru, the motor accelerates again, and usual operation continues.
Figure 12.111 Use the Momentary Power Loss Ride-Thru Time and KEB Ride-Thru to Cancel KEB Operation
*1
When
L2-07 = 0.00
, the drive accelerates again as specified by the applicable
Acceleration Time [C1-01,
C1-03, C1-05, C1-07]
, and usual operation continues.
Cancel KEB Operation When Restoration of Power Occurs while the Control Power (Power Supply to the
Control Board) is Maintained
The following figure shows an example with this configuration:
•
L2-01 = 1, and L2-50 = 3 [KEB Stop Mode]
is set.
•
KEB Ride-Thru is not used.
The drive starts deceleration through KEB operation. The drive decelerates for the time set in parameter
L2-10
,
and then measures the DC bus voltage level. When the DC bus voltage is lower than the level set in
L2-11
, the
drive uses the KEB Ride-Thru function to continue deceleration. When the DC bus voltage is more than the level
set in
L2-11
, usual operation continues. The drive accelerates the motor to the frequency reference value before
the power loss, and usual operation continues.

Control Power (Power Supply to the Control Board) is Maintained
*1
When
L2-07 = 0.00 s
, the drive accelerates again as specified by the applicable
Acceleration Time [C1-01,
C1-03, C1-05, C1-07]
, and usual operation continues.
Use the KEB Ride-Thru to Cancel KEB Operation when Restoration of Power Occurs while the Control
Power (Power Supply to the Control Board) is Maintained
The following figure shows an example with this configuration:
•
L2-01 = 1, and L2-50 = 1 [While CPU Active]
