# Step Restrictions

The availability of tightening steps, monitors and restrictions depends on the license installed on the controller.

To make sure the tightening stops if something unexpected happens, it is possible to add step restrictions to the multistep tightening program. These restrictions could, for example, test that a maximum torque is not reached or that a part of the multistep tightening does not take too long to run. Each step has its own set of mandatory step restrictions and optional step restrictions. The mandatory restrictions are included when dragging a new step to the multistep program. All steps can have up to four restrictions each.

In Power Focus 6000 StepSync and Power Focus 8 StepSync controllers, it is possible to use synchronization points in the tightening program. When any condition that is set for a restriction is met, the tool will be stopped immediately and the program jumps to the next synchronization point (only valid for the Power Focus 6000 StepSync, Power Focus 8 StepSync and Flex), or the end of the program. In controllers without StepSync the tool is stopped immediately and the program jumps to the end of the program.

For Flex only:

For each restriction, select Repairable = Yes to allow retry when tightening stops.

The following restrictions are automatically added to every step that is added to the multistep tightening program.
