 Setting Pr.06-48 to 0 disables the OPHL detection function before operation.
 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.
