Description
V/f CL-V/f OLV CLV AOLV
Sets the proportional gain to calculate acceleration and deceleration rates.
V/f CL-V/f OLV CLV AOLV
Sets the momentary deceleration time that the drive will use when it tries to accelerate a
PM motor and detected motor stalls. This function is applicable when L3-01 = 1 [Stall
Prevention during Accel = Enabled].
V/f CL-V/f OLV CLV AOLV
Sets the function to automatically decrease the Stall Prevention Level during Run for
Constant Horse Power (CHP) part of the speed range.
0 : Use L3-06 for Entire Speed Range
1 : Automatic Reduction @ CHP Region
V/f CL-V/f OLV CLV AOLV
Sets the motor acceleration time to reach the maximum frequency at the motor rated
torque for stopped single-drive motors.
V/f CL-V/f OLV CLV AOLV
Sets the ratio between motor inertia and machine inertia.
V/f CL-V/f OLV CLV AOLV
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 CL-V/f OLV CLV AOLV
Sets a delay time between reaching the Stall Prevention level and starting the Stall
Prevention function.
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.
V/f CL-V/f OLV CLV AOLV
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 CL-V/f OLV CLV AOLV
Sets the function to enable and disable the best S-curve characteristic used for current-
limited acceleration.
0 : Disable
1 : Enabled
Description
V/f CL-V/f OLV CLV AOLV
Sets the level to detect speed agree or motor speed.
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 CL-V/f OLV CLV AOLV
Sets the width to detect speed agree or motor speed.
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].
