12.9 L: Protection Functions
■
L1-08: oL1 Current Level
No.
Name
(Hex.)
L1-08 oL1 Current Level
(1103)
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.
Name
(Hex.)
L1-09 oL1 Current Level for
Motor 2
(1104)
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.
Name
(Hex.)
L1-13 Motor Overload Memory
Selection
(046D)
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.
Name
(Hex.)
L1-22 Leakage Current Filter
Time1
(0768)
RUN
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.
Name
(Hex.)
L1-23 Leakage Current Filter
Time2
(0769)
RUN
670
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
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.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
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.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the function that keeps the current electronic thermal protector value when the drive stops
receiving power.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the leakage current detection reduction filter time constant during constant speed run.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the leakage current detection reduction filter time constant during acceleration/deceleration.
