To use my (Pico Systems) gear, you would need our encoder converter board, as the commutation signals from the encoder are not industry standard. They provide 4 signals that give a Gray code approximation of absolute rotor position, for their own commutations scheme. Our Fanuc converter converts this to an approximation of the standard Hall signals until it has seen the index pulse, then it uses the quadrature plus index to provide the most accurate Hall signals.) > Yes, I can see they "only" have 2.2KW, I would need ~3KW.

You'd then feed just ABZ back to the Mesa board, and PWM and direction to the servo amp.
