Drive status o8.0

Victor_R Posts: 3 Rating: (0)	Hello. Two DC drives are used on the rewinder machen. Control takes place via Profibus-DP PPO5. Before starting the machine, both DC drives have o7.1 status. After starting the machine, one drive starts (RUN mode), the second drive changes to the o8.0 state. Using the program Drive Monitor, I saw that the OFF2 signal for a short time disappears. Why is this happening? In the drive, in parameters P655, P656 and P657, the binector B0001 is writed. Best regards, Victor
