Description
1 KEB-1
When the input power is disconnected, it charges
the DC link with regenerated energy. When the
input power is restored, the inverter changes to
normal operation from the KEB-1 energy buffering
operation. The acceeration time set in Cn.83 (KEB
Acc Time) is applied when restoring to normal
operation.
2 KEB-2
When the input power is disconnected, it charges
the DC link with regenerated energy. When the
input power is restored, it changes from the KEB-2
energy buffering operation to the deceleration
stop operation. The decel time set in the dEC
parameter of the operations group is applied
during the deceleration stop operation.

Sets the start and stop points of the kinetic energy buffering operation.
The set values must be based on the low voltage trip level as 100% and
the stop level (Cn.79) must be set higher than the start level (Cn.78).
