Kinetic Energy Buffering Operation Setting Details
Code
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.
1
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.
