In that particular system, the high encoder resolution pretty much required the hardware support. I think it was 16384 step pulses per revolution.
The Minertia motors are exotic ironless-rotor motors designed for high acceleration. I don't know anything about the FR series of drives, but they are likely to be standard velocity servos. Do the motors have tachometers? That would be a strong indication the drive is a velocity servo. If so, it is likely to take a +/- 10 V velocity command. A little searching indicates the FR01RB7-R2M is probably a CPCR-FR01RB7-R2M, but I couldn't find anything on the Yaskawa site on this product. You can use some other servo drives for these motors.
