EVAL229QR Not Enabling

I purchased the L6229Q eval board and have connected to a 3-phase BLDC motor (H1, H2, H3, OUT1, OUT2, OUT3). I have VDD and EN connected to a 5V supply with SGND and VS connected to a sceond 12V supply with PGND. I am getting no response when I apply 0-5V signal to Vref (SGND reference) and there is no output on TACHO when I rotate the motor by hand (but I can see PIN 25-27 getting correct 5V inputs.)

Is it a bad device or have I misunderstood connections?
