Hello everybody!!
One of our machines have a Siemens 315 2DP and a Micromaster 430 drive. While powering up the drive (400V, 3 phase) the Siemens CPU drives to Bus fault.
The power circuit has been isolated for the time being i.e Micromaster power has been given separately and the machine has a separate power.
It seems to be due to inefficient earthing. Please advise if anyone had faced such problems before.
