Parameter name | Description | Default Value
--- | --- | ---
Soft start | Enables setting of the tool’s speed, angle and maximum torque to facilitate the bolt entering the thread. Selected by radio buttons. Off: Soft start is turned off. On:Soft start is turned on. | Off
Speed | Defines the speed during the soft start. | 300 rpm
Time | Defines the Soft start duration. | 400 ms
Rehit detection | Early: Terminates the tightening immediately when an already tightened screw/bolt is detected. The tightening will be considered as NOK. Requires that Soft start is activated. Complete: Even though an already tightened screw/bolt is detected, the tightening is not terminated until all tightening steps have been executed. The tightening will be considered as NOK. To make a rehit detection when Soft start is not activated, the Rehit detection Complete option must be selected.

The tightening will be considered a rehit if the speed fails to reach half the rundown speed, a rehit error is then indicated. Off: No rehit detection will be performed. Combination Soft start = Off and Rehit = Early is not allowed. | Off
Use attachment tuning | Attachment tuning is selected by radio buttons. | No
Gear ratio | Socket rotation speed = Tool speed / gear ratio. | 1.00
