PL-RL etc just seem to be whatever they are depending on what mode you are in. For example if in Velocity mode they would seem to be internal speed commands. If that is the case then I do not think you want them connected. The manual is not that clear but it would seem that if Srom (n) has to be connected to Enable the drive then it follows that you do not want the others connected. The ZeroSpd one would be used as a safe stop in an E-Stop situation I would think, the signal would be applied which would stop the motion quickly then you could safely take away the Enable.
If you simply take away the Enable then, depending on axis friction, it could coast for a distance before coming to rest thus a lot of servos now have a means of stopping quickly under power in an emergency then you can disable. The drives I use on the Chiron have that function and I use a safety relay with a timer to control it.
Going back to your problem, I cant see anything that could be amiss with your setup if it is as you say, it should be working according to the manual, still would be better in Velocity mode though I think.
If you can get the file saved and zipped I can take a look and see if I can find a problem.
