● 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.

● Status 3:

The drive is in STOP; Pr.06-48 ≠ 0; Pr.07-02 ≠ 0

When the drive starts, it executes Pr.06-48 first, and then executes Pr.07-02 (DC brake). The DC brake current

level in this state includes two parts: one is 20 times the Pr.06-47 setting value in Pr.06-48 setting time; the

other is the Pr.07-01 setting value in Pr.07-02 setting time. The total DC brake time T = Pr.06-48 + Pr.07-02. In

this period, if an OPHL occurs within the time for Pr.06-48, the drive executes the Pr.06-45 setting after the

drive starts counting for half the time of Pr.06-48.
