Across 64 and 9 you should have 0 volt. If not your enable contact isn't closed.
The voltages you stated, what was your reference point. Did you measure to chassis ground? And remember to reset the fault. Do you leave the unit powered up? You can reset the fault by powering down, but that means everything, if there is a backup standby voltage from the Fanuc, you should disconnect it for a while after you powered down. You can bridge the terminals 64 and 9 manually to enable the drives, but stand by in case the motor takes off, especially while the CNC is booting up. On some systems there is an drives enable pushbutton, once the CNC controller has booted you press it to enable the drives. Is your system like that?
