increase in angle after the snug point results in a corresponding increase in the
tension or clamp load within the joint.
Soft Stop Soft stop minimizes the torque impulse to the operator during tool shutoff at the
end of the tightening cycle.
Speed The speed at which the tool operates during the initial portion of the tightening
cycle prior to ATC or downshift.
Spindle A spindle represents the tool, its cable and connected controller.
Strategy Identifies what variables will be used to control the tool during a tightening cycle.
Thread Direction Sets assembly direction to clockwise (CW) or counter clockwise (CCW).
Threshold Torque Sets the point at which the tool is considered to be "performing work", the tool and
controller tightening cycle status lights turn off, the controller displays dashes (----)
for data, and the "In Cycle" output is turned on.
Tool Tones Distinctive sounds assigned to tool functions.
Torque Calibration Determines how torque values are assigned to the electrical signals from the torque
transducer on the tool. This value is unique to each tool and changes over time.
Torque Target When the tool is being controlled for torque, the torque target instructs the
controller when to shut the tool off. The torque target should be greater than Low
Torque and less than High Torque, and is required for torque control.
Trace A display plot of torque vs. time (or angle) of a tightening cycle.
Trip Counter Records the number of tightening cycles completed since the last time it was reset.
It is usually used as a supplementary count of the PM Counter.
Units The following torque units and associated labels are used with Stanley controllers
and tools. The labels are derived from SP811, SI Unit rules and style conventions
from the National Institute of Standards and Technology
