L1-04
Motor Overheat Fault
Operation Selection (PTC
input)
Sets stopping method when the motor temperature analog
input (H3-02 and H3-10 = E) exceeds the oH4 fault level
(PTC input level: Tr-5°C).
0: Ramp to Stop
1: Coast to Stop
2: Fast-stop
0 to 2 1 A A A 483 188
L1-05
Motor Temperature Input
Filter Time (PTC input)
This parameter adjusts the filter on the motor temperature
analog input (H3-02 or H3-10 = E). Increase to add
stability, decrease to improve response.

L1-13
Continuous Electrothermal
Operation Selection
Determines whether or not to hold the electrothermal value
when the power supply is interrupted.
0: Disabled
1: Enabled
0 to 1 1 A A A 46D 189
L2: Momentary Power Loss Ride-Thru
Use L2 parameters to configure drive functions for momentary power loss conditions.
L2-01
Momentary Power Loss
Operation Selection
Enables and disables the momentary power loss function.
0: Disabled - Drive trips on (Uv1) fault when power is lost.
1: Power Loss Ride-Thru Time - Drive will restart if power
returns within the time set in L2-02.
2: CPU Power Active - Drive will restart if power returns
as long as the CPU is working.
0 to 2 0 A A A 485
189
For a restart to occur, the run
command must be maintained
throughout the Ride-Thru period.
L2-02
Momentary Power Loss
Ride-Thru Time
Sets the Power Loss Ride-Thru time. Only effective when
L2-01 = 1.
0.0 to 25.5
<11> AAA 486 189
L2-03
Momentary Power Loss
Minimum Baseblock Time
Sets the minimum wait time for residual motor voltage
decay before the drive output reenergizes after power loss
Ride-Thru. If L2-03 is greater than L2-02, operation
resumes after the time set in L2-03.
0.1 to 5.0
<33> AAA 487 189
L2-04
Momentary Power Loss
Voltage Recovery Ramp
Time
Sets the time for the output voltage to return to the V/f
pattern during Speed Search.
0.0 to 5.0
<33> AAA 488 190
L2-05

Undervoltage Detection
Level (Uv1)
Sets the DC Bus undervoltage trip level. This setting rarely
needs to be changed from the default value.
150 to 210

AAA 489 190
L3: Stall Prevention
Use L3 parameters to configure the Stall Prevention function.
L3-01
Stall Prevention Selection
during Acceleration
Selects the Stall Prevention method used to prevent
excessive current during acceleration.
0: Disabled - Motor accelerates at active acceleration rate.
The motor may stall if load is too heavy or accel time is too
short.
1: General Purpose - When output current exceeds L3-02
level, acceleration stops. Acceleration will continue when
the output current level falls below the L3-02 level.
2: Intelligent - The active acceleration rate is ignored.
Acceleration is completed in the shortest amount of time
without exceeding the current value set in L3-02.

<15>
Stall Prevention Level
during Acceleration
Used when L3-01 = 1 or 2.
100% is equal to the drive rated current.
Decrease the set value if stalling or excessive current
occurs with default setting.
0 to 150

Stall Prevention Limit
during Acceleration
Sets Stall Prevention lower limit during acceleration when
operating in the constant power range. Set as a percentage
of the drive's rated current.
