Parameters for KEB Ride-Thru
This table shows the parameters that adjust the KEB Ride-Thru function. Parameter settings are different for the
different KEB methods set in
L2-29 [KEB Method]

L2-07
KEB Accel Time
Sets the acceleration time to return to the frequency reference value before a
power loss, after you cancel the KEB operation. When
L2-07 = 0
, the drive uses
the standard acceleration times set in
C1-01, C1-03, C1-05, and C1-07

Minimum KEB Time
•
With KEB Ride-Thru
There is
Uv1
because you set a digital input for KEB Ride-Thru and the device
that controls the input operated too slowly after power loss.
•
Without KEB Ride-Thru
If the DC bus voltage overshoots immediately after KEB Ride-Thru starts,
increase L2-10 to longer than the overshoot.

•
If
ov
or
Uv1
occurs at the start of deceleration when you use KEB operation,
increase this value in 0.1-unit increments.
•
If there is torque ripple during deceleration when you use KEB Ride-Thru,
decrease the value.

OVSup Acc/Dec Gain
If there is large speed or current ripple, decrease the value in 0.05 unit increments.
Note:
If the setting value is too low, then the drive will have unsatisfactory DC bus
voltage control response. The drive can detect
ov
or
Uv1
