V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the width for speed agreement when L3-04 = 2 [Decel Stall Prevention Selection =
Automatic Decel Reduction]. Usually it is not necessary to change this setting.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
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 OLV OLV/PM OLV/PM AOLV/PM EZOLV
Suppresses current hunting during acceleration. Usually it is not necessary to change this setting.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Suppresses current hunting and overshooting that occurs when the drive stalls during acceleration.
Usually it is not necessary to change this setting.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the time constant to adjust the acceleration rate when L3-01 = 3 [Stall Prevention during
Accel = Current Limit Method]. Usually it is not necessary to change this setting.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the function to enable and disable the best S-curve characteristic used for current-limited
acceleration.
