L1-09: oL1 Current Level for Motor 2
Sets the reference current for motor thermal overload detection for motor 2 in amperes. When L1-09 is set to 0.0 A (default),
parameter E4-01 is used as the reference for motor overload protection. When L1-09
≠
0.0 A, the set value is used as the
reference for motor overload protection.

L2-01: Momentary Power Loss Operation Selection
When a momentary power loss occurs, the drive can automatically return to the operation it was performing prior to the power
loss based on certain conditions.

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 is not restored within this time (i.e.,
DC bus voltage level remains below Uv1 detection level L2-05), then an Fdv fault is triggered and the drive will stop.
Setting 2: Recover as long as CPU Has Power
When a momentary power loss occurs, the drive output will be shut off. If the power returns and the drive control circuit has
power, the drive will attempt to perform Speed Search and resume the operation. This will not trigger an Fdv fault.
Note:
1.
Keep the magnetic contactor closed during the momentary power loss when using a magnetic contactor between the motor and the drive
2.
“Uv” will flash on the operator while the drive is attempting to recover from a momentary power loss. A fault signal is not output at this
time.
