Hello everyone,
One of our machine we use Siemens Cpu315-2dp. And this cpu communicate with 4 Lenze servo drives series 9300 via profibus. Also this cpu communicate with hmi and another cpu via mpi. Lenze 9300 servo drive production stopped so we bought suggested new series 9400 works also with profibus. After updating parameters of 1 drive with lenze's support and hardware changes on cpu we replace one drive and machine started to work. But we relaized machine communicaton speed dropped significiantly. If i push some button on hmi machine reacts about 3-4 seconds later. And connection with other cpu goes timeout. Any idea appreciated
