Hi Andy, the encoder is the one on the picture I'm attaching now. The model number is *αI64 *and then TYPE A860-0365-T101. If the 8i20 can control both servo motors It surely would be a lot easier to replace the encoders in case they don't work with the HOSTMOT2 Fanuc component. I really prefer to avoid replacing the motors because they are already there with all the couplings and even the brake assembly for the X axis. The Z axis motor is rated at 3800 W but I don't mind having it limited to 2200 W given the kind of work this lathe does, (mostly cast iron parts with really light cuts so no big cutting forces involved). Thank you!
