Hello, looking at these Leadshine Ethercat motors (EML2H-0750LA80F) they have a 23 bit optical encoder and I am wondering what that means in terms of repeatable positioning accuracy. I understand imperial measurements .001, 0001, 00001 etc. So without considering any sort of backlash in the system what sort of repeatable positioning accuracy does a 23 bit optical encoder on these motors give you?

Thanks in advance! Gary
