L1-08: oL1 Current Level
No.
(Hex.)
Name Description
Default
(Range)
L1-08
(1103)
oL1 Current Level
Sets the reference current for the motor 1 thermal overload detection. When the current level > 0.0
A, you cannot set this value < 10% of drive rated current.
0.0 A
(0.0 A or 10% to 150% of
the drive rated current)
When L1-08 = 0.0 A , the drive uses E2-01 [Motor Rated Current (FLA)] to detect the motor overload protection.
In PM control mode, the drive uses E5-03 [PM Motor Rated Current (FLA)] to detect the motor overload
protection.
When
L1-08 ≠ 0.0 A
, the set value is the reference for motor overload protection.
Note:
•
Display is in these units:
– 0.01 A: 2001 to 2042, B001 to B018, 4001 to 4023
–
0.1 A: 2056 to 2082, 4031 to 4060
• When the current level > 0.0 A, you cannot set this value < 10% of drive rated current.

L1-09: oL1 Current Level for Motor 2
No.
(Hex.)
Name Description
Default
(Range)
L1-09
(1104)
oL1 Current Level for
Motor 2
Sets the reference current for the motor 2 thermal overload detection. When the current level > 0.0
A, you cannot set this value < 10% of drive rated current.
0.0 A
(0.0 A or 10 to150% of the
drive rated current)
When L1-09 = 0.0 A , the drive uses E4-01 [Motor 2 Rated Current] to detect the motor overload protection.
When L1-09 ≠ 0.0 A , the set value is the reference for motor overload protection.
Note:
• Display is in these units:
– 0.01 A: 2001 to 2042, B001 to B018, 4001 to 4023
– 0.1 A: 2056 to 2082, 4031 to 4060
•
When the current level > 0.0 A, you cannot set this value < 10% of drive rated current.

L1-13: Motor Overload Memory Selection
No.
(Hex.)
Name Description
Default
(Range)
L1-13
(046D)
Motor Overload Memory
Selection
Sets the function that keeps the current electronic thermal protector value when the drive stops
receiving power.
1
(0, 1)
0 : Disabled
1 : Enabled
Sets if the drive will calculate the motor again when the drive is energized again.
■
L1-22: Leakage Current Filter Time1
No.
(Hex.)
Name Description
Default
(Range)
L1-22
(0768)
RUN
Leakage Current Filter
Time1
Sets the leakage current detection reduction filter time constant during constant speed run.
Determined by C6-02
(0.0 - 60.0 s)
Note:
You can set this parameter when C6-02 = B [Carrier Frequency Selection = Leakage Current Detection Reduction Rate PWM] .
If incorrect detection of alarms, for example oL1 [Motor Overload] , occur or errors occur in the values on the
current monitor because of a leakage current, increase the setting value.
■
L1-23: Leakage Current Filter Time2
No.
(Hex.)
Name Description
Default
(Range)
L1-23
(0769)
RUN
Leakage Current Filter
Time2
Sets the leakage current detection reduction filter time constant during acceleration/deceleration.
Determined by C6-02
(0.0 - 60.0 s)
