But now and then, the message disappears and the motor starts until the message returns. What is the message and what to do to prevent it from popping up?

In the PLC-program I use a function to write the data to the drives. There I saw the address to send the data to was not changed (Step7 crashed so all changes lost...) So I was sending 2 different commands to 1 drive. And this one didn't understand what happened. I changed the addresses and everything works perfect again
