How about the 6-Bit (06B) interpolation on the read head is 64 and the ring has 72 poles. I am unsure as to how this equates to the "Spindle Encoder Counts" in Acorn: Would this be 4608 (64 x 72) Spindle Encoder Counts or something else?
Hum, not sure just what those specs are saying. The 72 poles makes sense but the 64 on the read head throws me off a bit.
If it is a quadrature encoder, then you get four pulses per line on the encoder so 4 x 72 = 288
It real simple to figure out though. Just wire up the encoder to acorn, turn the spindle by hand one full turn while you have the software open to the "Motor" tab.
F1 setup, then F3 config, then F2 Machine and last hit F2 for Motor and then watch the encoder counts as you turn the spindle by hand one exact turn, or as close as you can to one exact turn.
That reading will be close and you can do the math to get the exact reading. So lets say it read 285. Then you will know that it should be 288!
I'm not familiar with your encoder but I would guess it will output much higher pulse train than 288. Maybe 4,608 or 18,432 (just a guess)
