For armature circuit hardware configuration is like this: 1. ADVANCED CUD C98043-A7100 + CBE20 + BOP20 + AOP30 2. SINAMICS DCM 6RA8000-0MV62-0AA0 3. Existing BC6 thyristor bridge For excitation circuit hardware configuration is like this: 1. ADVANCED CUD C98043-A7100 + CBE20 + BOP20 2. SIMOREG CONVERTER 6RA8075-6DS22-0AA0 Communication between armature and excitation CUD is going trough peer-to-peer terminals -X177: 37,38,39,40. Communication between excitation CUD and SIMOREG converter is going trough allocation board terminal -X108. Motor have to work in field weaking, so it means that setpoint for field current must come from armature controler. My question is how to establish proper communication settings to send field current setpoint from Sinamics DCM to Simoreg converter? Is it possible with hardware configuration that I have? Thanks in advance! Best regards, Almen
