Well had a look at the 300ETH manual and it's not exactly helpful is it ?
22 Pages, 20 of which tell you how to connect the ethernet and then a scant 2 pages giving the wiring of the pins.

aHowever they are all marked output 1, output2, etc, Analog 1, analog 2

Would it really hurt these peole is they supplied a diagram for a working 3 or 4 axis machine with VFD ?
You know it just might, note I said might, improve sales because at the moment anyone who isn't an EE is totally fazed by what has been released.

BTW can it do multiline encoder for lathe ?
