The voltage/amperage specs are so you can measure the friction when the axis moves. My machines have Mitsubishi controls where I can see the current load rate on each axis.
With most box and dovetail ways, there is one adjustment screw at each end of the gib. Initial gib adjusment is usually done using an indicator. As the mechanical slack is taken out of the axis by snugging the gib, the voltage/amperage of the servo becomes more useful for checking for an overtightened gib.
