<9> Default setting is determined by the drive model (o2-04) and duty selection (C6-01).
<12> Setting range value is dependent on the units selected for the accel/decel time (C1-10). When C1-10 = 0 (units of 0.01 s), the setting range
becomes 0.00 to 600.00 s.
<18> Values shown here are for 200 V class drives. Double the value when using a 400 V class drive.
<33> Default setting value is dependent on the setting for the input voltage (E1-01).

YASKAWA ELECTRIC TOEP C710616 21C YASKAWA AC Drive - A1000 Quick Start Guide
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.
Note: Setting 2 is not available when using OLV/PM.
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 the drive's 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.
0: Disabled. Drive runs at a set frequency. A heavy load may cause speed loss.
1: Decel time 1. Uses the deceleration time set to C1-02 while Stall Prevention is
performed.
2: Decel time 2. Uses the deceleration time set to C1-04 while Stall Prevention is
performed.
Enabled when L3-05 is set to 1 or 2. 100% is equal to the drive rated current.
Enables or disables the ov suppression function, which allows the drive to
change the output frequency as the load changes to prevent an ov fault.
0: Disabled
1: Enabled
