
When power failure occurs in the input power, the DC link voltage of the inverter gets low and low
voltage trip occurs. Its function is to maintain the voltage of DC link by controlling output frequency of the
inverter during the time of power failure. That is, it can keep the time from the point of power failure to low
voltage trip long.

Selects energy buffering operation when input power is cut. If H64 is set to 0, it operates normal
deceleration run until low voltage occurs. When H64 is set to 1, it controls the inverter output frequency
and charges the energy occurred from the motor to the inverter DC.

H65 (KEB operation start level), H66 (KEB operation stop level): Selects starting and stopping point of
the energy buffering operation. Set the stop level (H65) higher than the start level (H66) setting the low
voltage trip level as standard.

H37 (Load inertia): Uses the momentum amount of the load inertia to control energy buffering operation.
If the inertia ratio is set high, the frequency change range gets small when running energy buffering.
