<1> Default setting is dependent on parameter o2-04, Drive Model Selection.
<2> Default setting is dependent on parameter E1-01, Input voltage Setting.
<3> Values shown are specific to 200 V class drives. Double the value for 400 V class drives. Multiply the value by 2.875 for 600 V class drives.
<4> Setting range value is dependent on parameter C1-10, Accel/Decel Time Setting Units. When C1-10 = 0 (units of 0.01 seconds), the setting range
becomes 0.00 to 600.00 seconds.
<5> Values shown are specific to 200 V class drives. Double the value for 400 V class drives. Multiply the value by 2.875 for 600 V class drives, but
set the value below 1040 Vdc (overvoltage protection level).

Sets the DC bus undervoltage trip level.
Sets the time required to decelerate from the speed when KEB was activated
to zero speed.
Sets the time to accelerate to the frequency reference when momentary power
loss is over. If set to 0.0, the active acceleration time is used.
Sets the percentage of output frequency reduction at the beginning of
deceleration when the KEB Ride-Thru function is started.
Reduction = (slip frequency before KEB) × L2-08 × 2
Sets the time to perform KEB Ride-Thru.
Sets the desired value of the DC bus voltage during KEB Ride-Thru.
0: Single Drive KEB Ride-Thru 1
1: Single Drive KEB Ride-Thru 2
2: System KEB Ride-Thru 1
3: System KEB Ride-Thru 2
0: Disabled.
1: General purpose. Acceleration is paused as long as the current is above the
L3-02 setting.
2: Intelligent. Accelerate in the shortest possible time without exceeding the
L3-02 level.
Used when L3-01 = 1 or 2. 100% is equal to the drive rated current.
Sets Stall Prevention lower limit during acceleration when operating in the
constant power range. Set as a percentage of drive rated current.
0: Disabled. Deceleration at the active deceleration rate. An ov fault may
occur.
1: General purpose. Deceleration is paused when the DC bus voltage exceeds
the Stall Prevention level.
2: Intelligent. Decelerate as fast as possible while avoiding ov faults.
3: Stall Prevention with braking resistor. Stall Prevention during deceleration
is enabled in coordination with dynamic braking.
4: Overexcitation Deceleration. Decelerates while increasing the motor flux.
5: Overexcitation Deceleration 2. Adjust the deceleration rate according to the
DC bus voltage.
