Kinetic Energy Buffering Operation Setting Details
Code Description
CON-77
KEB Select
Select the kinetic energy buffering operation when the input power is
disconnected.
Setting Function
0 No General deceleration is carried out until a
low voltage trip occurs.
1 Yes The inverter power frequency is controlled
and the regeneration energy from the motor
is charged by the inverter.
CON-78
KEB Start Lev,
CON-79
KEB Stop Lev
Sets the start and stop points of the kinetic energy buffering operation.
The set values must be based on the low voltage trip level at 100%, and
the stop level (CON-79) must be set higher than the start level (CON-78).
CON-80
KEB Slip Gain Used to prevent malfunctions caused by low voltage from initial kinetic
energy buffering occurring due to power interruptions.
CON-81
KEB P Gain
Used to maintain the voltage during the kinetic energy buffering operation.
It operates the inverter by modifying the set value to prevent malfunctions
caused by low voltage after power interruptions.
CON-82 Used to maintain the voltage during the kinetic energy buffering operation.
