L1-04
(483H)
Motor Overheat Fault Operation
Selection (PTC input)
Sets stopping method when the motor temperature analog input (H3-02, H3-06, or H3-10 = E)
exceeds the oH4 fault level.
0: Ramp to stop
1: Coast to stop
2: Fast Stop (decelerate to stop using the deceleration time in C1-09)
Default: 1
Min: 0
Max: 2

Motor Temperature Input Filter
Time (PTC input)
Adjusts the filter for the motor temperature analog input (H3-02, H3-06, or H3-10 = E).
Default: 0.20 s
Min: 0.00 s
Max: 10.00 s

<34> Default setting is determined by the control mode (A1-02).
No. (Addr.)
<6> The setting value is dependent on the setting for the input voltage (E1-01).
<15> Values shown here are for 200 V class drives. Double the value when using a 400 V class drive.
<24> Default setting is determined by the drive model (o2-04) and duty selection (C6-01).

L2-01
(485H)
Momentary Power Loss Operation
Selection
0: Disabled. Drive trips on (Uv1) fault when power is lost during Run.
1: Recover within the time set in L2-02. Uv1 will be detected if power loss is longer than L2-02.
2: Recover as long as CPU has power. Uv1 is not detected.
Default: 0
Min: 0
Max: 2
217
L2-02
(486H)
Momentary Power Loss Ride-Thru
Time
Sets the Power Loss Ride-Thru time. Enabled only when L2-01 = 1 or S4-01 = 2.
Default:
<24>
Min: 0.0 s
Max: 25.5 s
217
L2-03
(487H)
Momentary Power Loss Minimum
Baseblock Time
Sets the minimum wait time for residual motor voltage decay before the drive output
reenergizes after performing Power Loss Ride-Thru.
Increasing the time set to L2-03 may help if overcurrent or overvoltage occur during Speed
Search or during DC Injection Braking.
Default:
<24>
Min: 0.1 s
Max: 5.0 s
217
L2-04
(488H)
Momentary Power Loss Voltage
Recovery Ramp Time
Sets the time for the output voltage to return to the preset V/f pattern during Speed Search.
Default:
<24>
Min: 0.0 s
Max: 5.0 s
217
L2-05
(489H)
Undervoltage Detection Level
(Uv)
Sets the DC bus undervoltage trip level.
Default: 190 V

Min: 150 Vdc <15>
Max: 250 Vdc <15>

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.
Note: Setting 2 is not available when using OLV/PM.
Default: 1
Min: 0
Max: 2
218
L3-02
(490H)
Stall Prevention Level during
Acceleration
Used when L3-01 = 1 or 2. 100% is equal to the drive rated current.
Default:
<4>
Min: 0%
Max: 150%
<4>
219
L3-03
(491H)
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.
Default: 50%
Min: 0%
Max: 100%
219
L3-04
(492H)
Stall Prevention Selection during
Deceleration
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 1. Decelerates while increasing the motor flux.
5: Overexcitation Deceleration 2. Adjust the deceleration rate according to the DC bus voltage.
Default: 1
Min: 0
Max: 5
