Re: new servo motor controller

Roger,

I think I understand the confusion now. The Pixie P100 can work with
any count encoder. The Pixie P100 also has a step multiplier (x1 to
x255) that can be used in systems that have high count encoders and
cannot generate steps at a high enough frequency to run these motors
at a desired speed.

The P100-F20 (and P100-F25) are special versions of the board that
have extra circuitry to deal with certain Fanuc brushless motors that
do not have normal hall outputs. These versions can also be used with
other brush or brushless motors using any count encoder.

Hope that clears things up.
