Sets the method of Stall Prevention During Acceleration.
0 : Disabled
1 : Enabled
2 : Intelligent (Ignore Decel Ramp)
Sets the output current level to activate the Stall Prevention function during acceleration as
a percentage of the drive rated output current.
Sets the lower limit for the stall prevention level used in the constant output range as a
percentage of the drive rated output current.
Sets the method that the drive will use to prevent overvoltage faults when decelerating.
0 : Disabled
1 : General Purpose
2 : Intelligent (Ignore Decel Ramp)
4 : Overexcitation/High Flux
Sets the function to enable and disable Stall Prevention During Run.
Note:
An output frequency lower than 6 Hz will disable Stall Prevention during Run. The L3-
05 and L3-06 [Stall Prevent Level during Run] settings do not have an effect.
0 : Disabled
1 : Deceleration Time 1 (C1-02)
2 : Deceleration Time 2 (C1-04)
Sets the output current level to enable the Stall Prevention function during operation as a
percentage of the drive rated output current.
Note:
This parameter is applicable when L3-05 = 1, 2 [Stall Prevention during RUN =
Deceleration Time 1 (C1-02), Deceleration Time 2 (C1-04)].
Sets the overvoltage suppression function.
0 : Disabled
1 : Enabled
the Decel Stall Prevention function (Intelligent Stall Prevention) are active.
Sets the proportional gain used to control the DC bus voltage.
Sets the proportional gain to calculate acceleration and deceleration rates.
Sets the function to automatically decrease the Stall Prevention Level during Run for
constant output ranges.
0 : Use L3-06 for Entire Speed Range
1 : Automatic Reduction @ CHP Region
Sets the motor acceleration time to reach the maximum frequency at the motor rated torque
for stopped single-drive motors.
Sets the ratio between motor inertia and machine inertia.
Sets the capacity for external main circuit capacitors. Usually it is not necessary to change
this setting.
Sets a delay time between reaching the Stall Prevention level and starting the Stall
Prevention function.
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.
