4.2.5.14 AC_TCOMP Display of Torque Compensation Value
LED Display:
The bottom LED display field can be configured to
display the Torque Compensation Tare Value by using the toggle
button to select ‘COMP’ from the available options.
Run Screen:
In addition to the Final Audit Torque, the Final Torque
Total and the Torque Compensation Value will be displayed if an
AC_TComp stage was completed during the rundown.
4.2.5.15 Yield Control
This strategy detects the yield of the fastener and reports the
torque and angle that resulted from the fastening event.
Controlling by detecting Yield is very beneficial on joints where
clamp load varies greatly relative to final torque.
This strategy can be used alone or combined with other strategies
as steps in a parameter set. As an example, a common fastening
strategy could be three steps:
•
Torque Stage – To set a minimum threshold
•
Yield Stage – To control clamp load
•
Angle Stage – To attain a specific bolt stretch above Yield
Yield Target %
: Programmable with a default setting of 50%.
The lower this value, the more sensitive the strategy will be. Too low
could cause early and false detection.
The higher this value, the less sensitive the strategy will be. A more
pronounced change in slope is required for the yield to be determined.
The measurement is joint specific and 0% when parallel to the slope determined to be the elastic range
and 100% is when the slope is horizontal.
Joint Rate parameters have default settings of 5 samples every 20 degrees. This resolution can be
adjusted if needed.
