Hey there! I'm looking at upgrading our old Mitsubishi FX PLCs to something more modern, but I'm really worried about the servo drives. We've got a bunch of existing servo systems that work fine, and I don't want to end up with a massive rewiring project that costs a fortune and takes forever. What should I be thinking about to make sure the new PLC plays nice with our current servo drives?
