12.9 L: Protection Functions
876 YASKAWA SIEPC71061705H GA700 Series Technical Manual
2 : Fast Stop (Use C1-09)
The drive stops the motor in the deceleration time set in C1-09 [Fast Stop Time]. Fault relay output terminal MA-
MC turns ON, and MB-MC turns OFF.
■ L1-05: Motor Thermistor Filter Time
No.
(Hex.)
Name Description
Default
(Range)
L1-05
(0484)
Motor Thermistor Filter
Time
Sets the primary delay time constant for the PTC input signal entered to the drive. This parameter
prevents accidental motor overheat faults.
0.20 s
(0.00 - 10.00 s)
■ 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:
• The display units are different for different models:
–Models 2004 to 2042, 4002 to 4023: 0.01 A
–Models 2056 to 2415, 4031 to 4675: 0.1 A
• 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:
• The display units are different for different models:
–Models 2004 to 2042, 4002 to 4023: 0.01 A
–Models 2056 to 2415, 4031 to 4675: 0.1 A
• 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.
◆ L2: Power Loss Ride Through
L2 parameters set the drive operation during momentary power loss and the KEB Ride-Thru function method of
operation.
