actually im quite unlucky, as i dont have any of your nice drives, as i was hoping to make do with some amc ones until i scraped together enough cash to upgrade.
i dont have a scope here, so my testing method is a bit creative. That said i have identified C and !C lines, so it must be wired as a differential encoder without commutation.
My choices now seem to be either find a way to get the back off and hope the encoder actually has commutation, and its just a custom wire (only one encoder listed with this range on sanyodenki, and it has commutation tracks).
That or buy 4 VSD-As now, which would be a nice solution if i had that kind of cash lying around. Also i had planned to be doing just torque control on the drives, and closing the control loop in EMC with a mesa interface board. The changeover kind of ruins that idea. |
