Pr. 06-44 = 1: STO Alarm no Latch. After you clear the cause of the STO Alarm, the STO Alarm
clears automatically.
All of STL1–STL3 errors are “Alarm Latch” mode (in STL1–STL3 mode, the Pr. 06-44 function is
no effective).
Treatment to Output Phase Loss Protection (OPHL)
Default: 3
Settings 0: Warn and continue operation

The OPHL protect function is active when the setting is not 3.

Settings 0.000–65.535 sec.
Current Detection Level for Output Phase Loss
Default: 1.00
Settings 0.00–100.00%

Setting Pr. 06-48 to 0 disables the OPHL detection function.
Status 1: The drive is in operation
When any phase is less than the Pr. 06-47 setting, and exceeds the Pr. 06-46 setting time, the
drive executes according to the Pr. 06-45 setting.
Status 2: The drive is in STOP; Pr. 06-48 = 0 ; Pr. 07-02 ≠ 0
After the drive starts, the DC brake operates according to Pr. 07-01 and Pr. 07-02. During this
period, OPHL detection is not active. After the DC brake action is completed, the drive starts to
run, and enables the OPHL protection as mentioned above for status 1.
