E852: One key pressed during the movement
During the system movements, the keyboard is inactive, but at the pressure of >0<
button all movements are stopped and this message is displayed.
This function allows the user to stop the system movements in case an unexpected
system behavior or a collision during the system positioning.
1.
Make sure that >0< button was not intentionally/unintentionally pressed
during a unit movement: reset the unit and verify if the error is still present.
2.
Check that the >0< button is not stuck: replace the keyboard membrane if the
>0< button is faulty.
3.
If the tests are OK, refer to error E850 (see paragraph 9.2.8.1).
