Setting 0: Ramp to Stop
The drive stops the motor using the deceleration time 1 set in parameter C1-02.
Setting 1: Coast to Stop
The drive output is switched off and the motor coasts to stop.
Setting 2: Fast Stop
The drive stops the motor using the Fast Stop time set in parameter C1-09.

L1-08: oL1 Current Level
Sets the reference current for motor thermal overload detection for motor 1 in amperes. When L1-08 is set to 0.0 A (default),
parameter E2-01 (E5-03 in PM control modes) is used as the reference for motor overload protection. When L1-08
≠
0.0 A,
the set value is used as the reference for motor overload protection.

Setting 0: Disabled
If a momentary power loss occurs, a power supply frequency fault (Fdv) is detected and the drive output is turned OFF. The
motor coasts to stop.
Setting 1: Recover within L2-02
When a momentary power loss occurs, the drive output will be shut off. If the power returns within the time set to parameter
L2-02, the drive will perform Speed Search and attempt to resume operation. If power does not return within this time, it will
trigger a Uv1 fault.
