Had a look at the TekNix manual and it calls it ppr but as you say that it must be multiplied by 4. I think it was just my understanding of what ppr was that was confusing me. Now I know whatever the count of an encoder is advertised it is the line count.
Thanks for keeping me straight on this.
Now all I need is to get some info on the voltage and current that the motors are using on this lathe, that way I will be able to make a half informed choice in which drives to get. I found some info on the motors on the polish manuafacturers site, gives max voltage and holding torque etc but no mention of current. I emailed asking for a torque/current curve but so far no reply.
