Kinetic Energy Buffering Operation Setting Details

Description
Cn.77 KEB Select
Select the kinetic energy buffering operation when the input power is
disconnected. If 1 or 2 is selected, it controls the inverter's output frequency
and charges the DC link (inverter's DC part) with energy generated from the
motor. Also, this function can be set using a terminal input. From the Pn
terminal function settings, select KEB-1 Select, and then turn on the terminal
block to run the KEB-1 function. (If KEB-1 Select is selected, KEB-1 or KEB-2
cannot be set in Cn-77.)

General deceleration is carried out until a low voltage trip
occurs.

KEB-1
When the input power is blocked, it charges the DC link with
regenerated energy. When the input power is restored, it
restores normal operation from the energy buffering
operation to the frequency reference operation. KEB Acc
Time in Cn-89 is applied as the operation frequency
acceleration time when restoring to the normal operation.
2
KEB-2
When the input power is blocked, it charges the DC link with
regenerated energy. When the input power is restored, it
changes from the energy buffering operation to the
deceleration stop operation. The Dec Time in dr-04 is applied
as the operation frequency deceleration time during the
deceleration stop operation.
