The controller P Gain is for maintaining the voltage of the DC link
section during the kinetic energy buffering operation. Change the
setting value when a low voltage trip occurs right after a power failure.
The controller I Gain is for maintaining the voltage of the DC link
section during the kinetic energy buffering operation. Sets the gain
value to maintain the frequency during the kinetic energy buffering
operation until the inverter stops.
The slip gain is for preventing a low voltage trip due to load when the
kinetic energy buffering operation starts.
When power is restored, sets the acceleration time of the operating
frequency when the inverter returns to normal operation from KEB-1
mode.
Depending on the duration of Instantaneous power interruptions and the amount of load
inertia, a low voltage trip may occur even during a kinetic energy buffering operation.
Motors may vibrate during kinetic energy buffering operation for some loads.
