V/f OLV/PM OLV/PM EZOLV
Sets the capacity for external main circuit capacitors. Usually it is not necessary to change this
setting. Sets this parameter when you use the KEB Ride-Thru function.
V/f OLV/PM EZOLV OLV/PM
Sets a delay time between reaching the Stall Prevention level and starting the Stall Prevention
function.
V/f OLV/PM EZOLV OLV/PM
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/PM OLV/PM EZOLV
Sets the level to detect speed agree or motor speed when H2-01 to H2-03 = 2, 3, 4, 5 [MFDO
Function Selection = Speed Agree 1, User-set Speed Agree 1, Frequency Detection 1, Frequency
Detection 2].
V/f OLV/PM OLV/PM EZOLV
Sets the width to detect speed agree or motor speed when H2-01 to H2-03 = 2, 3, 4, 5 [MFDO
Function Selection = Speed Agree 1, User-set Speed Agree 1, Frequency Detection 1, Frequency
Detection 2].
V/f OLV/PM OLV/PM EZOLV
Sets the speed agree detection level or motor speed detection level when H2-01 to H2-03 = 13, 14,
15, 16 [MFDO Function Selection = Speed Agree 2, User-set Speed Agree 2, Frequency Detection 3,
Frequency Detection 4].
V/f OLV/PM EZOLV OLV/PM
Sets the width to detect speed agree or motor speed when H2-01 to H2-03 = 13, 14, 15, 16 [MFDO
Function Selection = Speed Agree 2, User-set Speed Agree 2, Frequency Detection 3, Frequency
Detection 4].
