Default: 1.0 min
Min: 0.1 min
Max: 5.0 min
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

Default: 3
Min: 0
Max: 3
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)

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
L3-02
(490H)
Stall Prevention Level during
Acceleration
Used when L3-01 = 1 or 2. 100% is equal to the drive rated current.
Default:
Min: 0%
Max: 150%
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
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:
Min: 30%
Max: 150%
