Sinusoidal Signals can be easily converted into TTL RS-422. There are some Chips from IC-haus that make this without big effort. And the price is ridiculously low compared with a HH Exe.

Jazz, is it possible to add linear scales to a IP/M or S control. I have now the "little" Boxford machine and want to convert it later to a servo control, I already have the Motors from Yaskawa and 2 drives for it but they want analog +/-10V. Now I need 3 additional drives for X,Y,Z and another one for B. If I see it right, I have 2 additional analog outputs which can have +/- 10V.
One for an additional 5th axis and one for the spindlemotor which I will change for a much stronger one.
But it were better, if I can add a linear or rotational scale to any axe.
I know the IP/A can make this, but this part is too expensive for me. With all features I want have, it costs more than 1000€.
