We have a IRBP L-1000 positioner that is giving a 50052 joint speed error after activation/deactivation of the mechanical unit.
The positioner has a fixturing table that is off-center of the rotating axis. When it is rotated past ~30 degrees to either side, an ActUnit or DeactUnit instruction would cause the brakes to release momentarily and drop a few inches. The brakes will reengage and throw a 50052 error.
What's odd is that this set up has been working for the past 4 years without issue, and we have an identical set up beside it that works.
This also happens if we manually jog it to one side and toggle the activate/deactivate button.
Am I missing something? Any suggestions appreciated!
