5.23 Kinetic Energy Buffering
When the input power supply is disconnected, the inverter‘s DC link voltage decreases, and
a low voltage trip occurs blocking the output. A kinetic energy buffering operation uses
regenerative energy generated by the motor during the blackout to maintain the DC link
voltage. This extends the time for a low voltage trip to occur, after an instantaneous power
interruption.

If a fault trip occurs during a time event operation, the inverter stops the operation and
stays in a trip state. When this happens, there are two options to resume the stopped
operation:
•
Set PRT-08 (RST Restart) to ‗YES‘ to allow the inverter to automatically restart after
the trip condition is released.
•
Refresh the setting at AP3-70 (Time Event En). Set AP3-70 to ‗Yes‘ from ‗No‘. If one of
the input terminals (IN-65–71 Px Define) is assigned to it, turn the swtich off then turn it
back on to resume the time event operation.
