Kinetic Energy Buffering (KEB) Operation
When the input power supply is disconnected the inverter’s DC link voltage decreases and a low
voltage trip occurs shutting off the output. A kinetic energy buffering (KEB) operation uses
regenerative energy from the motor to maintain the DC link voltage. This extends the time before a
low voltage trip occurs, after the power interruption.

Kinetic Energy Buffering Operation Setting Details
Code Description
Cn.77 KEB Select
Select the KEB (kinetic energy buffering) operation for installations that have
frequent power source interuptions. When either KEB-1 or KEB-2 is selected,
it controls the inverter's output frequency and charges the DC link with energy
generated from the motor.
This function can also be enabled using a digital input. From the Pn terminal
function settings, select (52)KEB-1 Select, and then activate the input to
enable the KEB-1 function. Note: If KEB-1 Select is set via the Pn terminal,
