I doubt this will be an issue. I did an application a while back
(years) incrementing a position in hal for a linear drive that was
actually a chain loop. So the servo motor always ran in the same
direction. Rollover of the position counter was brought up then and
calculations were made.

One thing to be aware of: If your application runs the motors in the same
direction for long periods of time, absolute position will keep increasing even
though relative position doesn't change. If HAL still uses single precision
(32bit) floats, you eventually might start losing resolution.

We have a project requiring four servo motors run synchronously, with
the ability to adjust the phase angle between motors. The motors will
be ramped up and down in velocity (remaining synchronized), but with
programmable phase offsets. We will be using AutomationDirect 400W
servos, with 1
