<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).

V/f V/f w/PG
OLV/PM AOLV/PM
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
All Modes
Sets the time to perform KEB Ride-Thru.
All Modes
Sets the desired value of the DC bus voltage during KEB Ride-Thru.
All Modes
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
V/f V/f w/PG
OLV/PM AOLV/PM
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.
V/f V/f w/PG
OLV/PM AOLV/PM
Used when L3-01 = 1 or 2. 100% is equal to the drive rated current.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets Stall Prevention lower limit during acceleration when operating in the constant power
range. Set as a percentage of the drive's rated current.
All Modes
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.
V/f V/f w/PG
OLV/PM AOLV/PM
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.
V/f V/f w/PG
OLV/PM AOLV/PM
Enabled when L3-05 is set to 1 or 2. 100% is equal to the drive rated current.
All Modes
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
All Modes
Sets the desired value for the DC bus voltage during overvoltage suppression and Stall
Prevention during deceleration.
All Modes
Sets the proportional gain for KEB Ride-Thru, Stall Prevention, and overvoltage suppression.
