# RT - Rescinding Torque

Tools
ES STR SL ST SR QST STB IXB

This restriction checks the torque. If the measured torque drops below the condition of the restriction the tool is stopped immediately and the program jumps to the next synchronization point (for Power Focus 6000 Synchronized Tightening and Power Focus 8 Synchronized Tightening), or the end of the program.

- Torque control processes
  The restriction condition is the measured torque. For the restriction to be active the torque must first exceed 110 % of the Rescinding Torque Limit.

- Angle control processes
  This restriction checks the maximum torque reached during the restriction. For the restriction to be active the torque must first exceed the Trigger Torque.

Torque control processes
Parameter | Description
--- | ---
Rescinding torque limit | Default: 10 Nm. Must be > 0.

Angle control processes (valid only for Power Focus 6000 Synchronized tightening and Power Focus 8 Synchronized tightening)
Parameter | Description
--- | ---
Trigger Torque | Must be > 0.
Peak torque percentage | Default: 95. Must be >= 50.
Rescinding torque time | Default: 20. Must be >= 5 and <= 500.
Rescinding Torque Angle | Must be > 0.

Cable tools have the option to select Rescinding Torque for Angle. This restriction is controlled by two parameters: Peak Torque Percentage and Rescending Torque Time. Percentage sets the downward deviation from the last peak torque, and Rescending Torque Time sets the duration (between 5 and 500 ms) of that deviation. Only when both conditions (equal to or lower than the indicated percentage for the set duration) are met, will the program be interrupted and jump to the end.
