 Status 3: Motor drive is in stop; Pr.06-48≠0 ; Pr.07-02≠0
When motor drive starts, it will perform Pr.06-48 and then Pr.07-02 (DC brake). DC brake
current level in this status includes two parts, one is 20 times of Pr.06-47 setting value in
Pr.06-48 setting time, and Pr.07-02 setting value in Pr.07-01 setting time. Total DC brake time is
T=Pr.06-48+Pr.07-02.
In this period, if OPHL happens, motor drive starts to count Pr.06-48/2 time, motor drive will
perform Pr.06-45 setting.
