Its function is to maintain the voltage of DClink by controlling output frequency of the inverter during the time of power failure. That is, itcan keep the time from the point of power failure to low voltage defect long. Selects energy buffering operation when input power is cut. If H64 is set to 0, it operatesnormal deceleration run until low voltage occurs. When H64 is set to 1, it controls the inverteroutput frequency and charges the energy occurred from the motor to the inverter DC. H 65(KEB operation start level), H 66(KEB operation stop level) : Selects starting and stoppingpoint of the energy buffering operation. Set the stop level(H65) higher than the start level(H 66)setting the low voltage defect level as standard. H 37(Load inertia) : Uses the momentum amount of the load inertia to control energy bufferingoperation. If the inertia ratio is set high, the frequency change range gets small when runningenergy buffering.8.20 DRAW driveGroup Display Parameter Name Setting Range Default UnitFunction F70 DRAW mode select - 0 ~ 3 0 -Group 1F71 DRAW ratio - 0.0 ~ 100.0 0.0 % It’s a kind of open loop tension control that uses the speed difference of motor running undermain frequency command to keep material’s tension in between steady.
