# Rehit Detection

When Rehit detection is activated, it is possible to detect a screw that has already been tightened.

Parameter | Description | Default value
--- | --- | ---
Rehit detection | Detects attempts to tighten an already tightened screw. Early: the Rehit detection Early option terminates the tightening immediately when a rehit is detected and ends the tightening in the most ergonomic possible way. To be able to use the Rehit detection Early option, Soft start must be set to On. This is because the Soft start torque max value is used as the torque limit beyond which the tightening is considered a rehit. The tightening is considered as NOK and a rehit error is indicated. Complete: to make a rehit detection when Soft start is not used, the Rehit detection Complete option must be used. Rehit detection Complete does not terminate the tightening until all tightening steps have been executed and consequently takes longer. The tightening is considered a rehit if the speed never reaches half the rundown speed, and a rehit error is indicated. The tightening is considered as NOK. Off: no rehit detection is performed. | Early
