◆ L: Protection Functions
L parameters provide protection to the drive and motor, including control during momentary power loss, Stall Prevention,
frequency detection, fault reset, overtorque detection, torque limits, and other types of hardware protection.
■ L1: Motor Protection
■ L2: Undervoltage Detection
■ L3: Stall Prevention
No. (Addr.) Name Description Setting Page
L1-01
(480H)
<1> Default setting is determined by the control mode (A1-02).
Motor Overload Protection
Selection
0: Disabled
1: General purpose motor (standard fan cooled)
2: Drive dedicated motor with a speed range of 1:10
3: Vector motor with a speed range of 1:100
5: PM motor with constant torque characteristics Default: <1>
Min: 0
Max: 5 213
L1-02
(481H)
Motor Overload Protection Time
Sets the motor thermal overload protection (oL1) time.
Default: 1.0 min
Min: 0.1 min
Max: 5.0 min 215
L1-03
(481H)
Motor Overheat Alarm Operation
Selection (PTC thermistor input)
Sets operation when the motor temperature analog input (H3-02 or H3-10 = E) exceeds the oH3
alarm level.
0: Ramp to stop
1: Coast to stop
2: Emergency Stop (Fast Stop) (decelerate to stop using the deceleration time in C1-09)
3: Alarm only (“oH3” will flash)
Default: 3
Min: 0
Max: 3 216
L1-04
(481H)
Motor Overheat Fault Operation
Selection (PTC thermistor input)
Sets stopping method when the motor temperature analog input (H3-02 or H3-10 = E) exceeds
the oH4 fault level.
0: Ramp to stop
1: Coast to stop
2: Emergency Stop (Fast Stop) (decelerate to stop using the deceleration time in C1-09) Default: 1
Min: 0
Max: 2 217
L1-05
(481H)
Motor Temperature Input Filter
Time (PTC thermistor input)
Adjusts the filter for the motor temperature analog input (H3-02 or H3-10 = E).
Default: 0.20 s
Min: 0.00 s
Max: 10.00 s 217
L1-13
(46DH)

Default: 1
Min: 0
Max: 1 215
No. (Addr.) Name Description Setting Page
L2-05
(489H)
<9> Values shown here are for 200 V class drives. Double the value when using a 400 V class drive.
<15> Default setting value is dependent on the setting for the input voltage (E1-01).
Undervoltage Detection Level
(Uv)
Sets the DC bus undervoltage trip level.
Default: <9> <15>
Min: 150 Vdc
Max: 210 Vdc
<9>
217
No. (Addr.) Name Description Setting Page
L3-01
(48FH)
Stall Prevention Selection during
Acceleration
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.
Default: 1
Min: 0
Max: 2 217
L3-02
(490H)
Stall Prevention Level during
Acceleration
Used when L3-01 = 1 or 2. 100% is equal to the drive rated current.
Default: <16>
Min: 0%
Max: 150%
<16>
219
L3-05
(493H)
Stall Prevention Selection during
Run
0: Disabled. Drive runs at a set frequency. A heavy load may cause speed loss.
1: Decel time 1. Uses the deceleration ramp set to C1-02 while Stall Prevention is performed.
2: Decel time 2. Uses the deceleration ramp set to C1-04 while Stall Prevention is performed.
Default: 1
Min: 0
Max: 2 219
L3-06
(494H)
Stall Prevention Level during Run
Enabled when L3-05 is set to 1 or 2. 100% is equal to the drive rated current.
Default: <16>
Min: 30%
Max: 150%
<16>
