50287: Unit not stopped in a controlled position

All,
I have a multi-move system. Dual Head robots with Operators panel.
I’m trying to execute Man Jog from the push of a button. It moves the external axis that’s on the operators side which is what i want but as soon as it stops executing/rotating the platter i get error message “50287” The robot ROB_1 is semi coordinated to unit STN2 from another task and the unit has been moved or the regain to the path failed.

Any Ideas?

Thanks

Must be some motion parameters, maybe the motion didn’t stop as expected, so the brakes are not adjusted or similar. How do you stop?
