The way I read the manual page 24 section H. It is saying the tach is a better option for fine motor control, but not required.
If you are using a spindle encoder as a tach source to have LinuxCNC control a +/- 10VDC connected between terminals COM and SIG (see figure 14). As Jon stated you will need a spindle control board that is isolated on power and ground - This is not just talking about opto isolators. That is a Cadillac of KB controllers as most will accept speed control - but not allow reversing without using an external physical switch/contactor and that is sensitive to switching under load. Be careful - no magic smoke! - bad for your health and painful in the wallet.
