When vibration occurs during operation of Single Drive KEB Ride-Thru 2, increase this parameter in 0.010-unit
increments.
Note:
The Single Drive KEB Ride-Thru 2 mode operates when L2-29 = 1 [KEB Method Selection = Single Drive KEB Ride-Thru 2] and H1-xx =
7A or 7B [Terminal Sx Function Selection = KEB Ride-Thru 2 (N.C./N.O.)].

V/f CL-V/f OLV CLV AOLV
Sets the filter time constant that returns the torque limit to its initial value when KEB operation
operates in Single Drive KEB Ride-Thru mode.
V/f CL-V/f OLV CLV AOLV
Sets the width for speed agreement when L3-04 = 2 [Stall Prevention during Decel = Intelligent
(Ignore Decel Ramp)]. Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the gain to suppress current and motor speed hunting during operation when L3-01 = 3 [Stall
Prevention during Accel = Current Limit Method]. Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Suppresses current hunting during acceleration. Usually it is not necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Suppresses current hunting and overshooting that occurs when the drive stalls during acceleration.
Usually it is not necessary to change this setting.
