There are two situations for the output phase loss detection: “detect when the drive is in operation”
and “detect before operation”. Setting Pr.06-48 to 0 disables the OPHL detection function before
operation.
The statuses of output phase loss detection are as following:
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.
