11.9 L: Protection Function
The drive ramps the motor to stop according to the deceleration time. Fault relay output terminal MA-MC will
turn on, and MB-MC will turn off.
1 : Coast to stop
The drive shuts off output and the motor coasts to stop. Fault relay output terminal MA-MC will turn on, and MB-
MC will turn off.
2 : Fast Stop
The drive stops the motor using the deceleration time set in C1-09 [Fast Stop Time]. Fault relay output terminal
MA-MC will turn on, and MB-MC will turn off.
3 : Alarm only
oH3 appears on the keypad, and operation continues.

When L1-08 = 0.0 A, the motor overload protection is detected on the basis of E2-01 [Motor Rated Current
(FLA)]. In PM control mode, the overload protection is detected on the basis of E5-03 [PM Motor Rated Current
(FLA)].
When L1-08 ≠ 0.0 A, the set value is used as the reference for motor overload protection.
Note:
• Display is in the following units:
–2004 to 2042, 4002 to 4023: 0.01 A units
–2056 to 2415, 4031 to 4675: 0.1 A units
• Cannot be set to a value smaller than 10% of drive rated current when the current level is set to a value greater than 0.0 A.

V/f CL-V/f OLV CLV AOLV
Selects the drive operation when the PTC input signal input into the drive
reaches the detection level of oH4 [Motor Overheat Failure].
V/f CL-V/f OLV CLV AOLV
Sets the primary delay time constant for the PTC input signal input to the
drive. This parameter is used to prevent accidental detections of motor
overheat fault.
V/f CL-V/f OLV CLV AOLV
Sets the reference current for motor thermal overload detection for motor 1
in amperes.
