Andy's link to AutomationTechnologies also brought me to DMM and their portfolio would look very promising with extremely attractive prices. But their encoders use a "proprietary serial protocol", which is only supported by their own drives. So no option, either. The reason for the 48V system is mainly safety, as it makes the design so much simpler if you don't have to care about all the HV stuff inside the machine. Everything else runs off 24V, there is no single wire running through the machine carrying mains power. The drive system supports several standard encoder interfaces, but nothing proprietary. Using the motor manufacturer's drive is not an option, as all motion components need to be connected to a high speed serial bus (similar to EtherCAT).
