0 : Ramp to Stop
The drive ramps the motor to stop in the deceleration time. Fault relay output terminal MA-MC turns ON and MB-
MC turns OFF.
1 : Coast to Stop
The output turns OFF and the motor coasts to stop. Fault relay output terminal MA-MC turns ON, and MB-MC turns
OFF.
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.
3 : Alarm Only
The keypad shows oH3, and operation continues. The output terminal set for Alarm [H2-01 to H2-03 = 10] turns ON.

L1-08: oL1 Current Level
No.

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.

V/f CL-V/f OLV CLV AOLV
Sets drive operation when the PTC input signal entered into the drive is at the oH3 [Motor Overheat
Alarm] detection level.
V/f CL-V/f OLV CLV AOLV
Sets the drive operation when the PTC input signal to the drive is at the oH4 [Motor Overheat Fault
(PTC Input)] detection level.
V/f CL-V/f OLV CLV AOLV
Sets the primary delay time constant for the PTC input signal entered to the drive. This parameter
prevents accidental motor overheat faults.
V/f CL-V/f OLV CLV AOLV
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.
