# ID 70090

Position deviation between master and slave axis exceeds permissible range.
Description | An error has occurred in gantry mode. The position lag between the master and slave axis is greater than the permissible path difference, which can still be corrected by resetting the controller.

- Possible causes:
- Great friction in the mechanical system
- The axis is blocked and can not move freely

Possible solutions:

- Reduce friction in the mechanical system
- Remove the obstacle
- See also [FCT-C11// Section: Overview]

Response | Class | 7 | Closed-loop controlled axis stop
Solution | Class | 6 | Reset the numerical control after solving the problem.
