We recently installed new drives (ACS880) in our Hot strip mill. the controller of the drive is AC800M. The master controller is AC450. Our issue here that all drives trips without material in the mill and is giving this alarm AFE2 Emergency stop (off1 or off3).
Action taken: to reset this alarm from the MMI whenever it come.
I have consulted the vendor and they say there is an issue with the communication.
Can you please advice or suggest any possible solution.
