I'm a little confused because of the ACS606 datasheet stated that the position following error should be +/- 1 count. Does anyone have a similar experience?
    Hi, have you solved this issue? I have an ACS806 and 57BL180D servo from Leadshine that suffer from a similar problem, the servo works below 530 rpm (the following error is high but it keeps spinning, without load) but if i exceed 530 rpm than the following error quickly jumps to the limit and stops the motor.
    Thanks, Matteo.

    No, I did not solve this issue. I tried tune these drivers (I have two and both have this issue) many times but without success. Even worse is fact that the following error is not constant but is depending on the actual speed. So In my opinion these drivers are totally useless for accurate positionig. You can see similar thread here.

    That should be the shield (braid) ground if its shielded (with braid). Normally this is grounded to chassis at only one end. In a star ground configuration using the cabinet as the reference it would be grounded here. If your system (encoder end) is grounded to chassis with a similar arrangement seen here but at the motor end put some insulation on this end to avoid a potential ground loop.

    I'll just leave it disconnected for now then, You would think that these encoder cables with 7 wires would be mentioned somewhere. There is not continuity with the multi-meter with the port end outer sheath. next best bet would be to try all the port holes to see if i get a signal.

    I'd definitely put some insulation on that exposed wire.
