The Final Torque Sample graph shows the final 
torque of each rundown in the collection.  
For reference, the Parameter Set values for Torque Hi, Torque Lo w, and Torque Target 
are taken from the first rundown in the  collection and plotted as vertical lines. 
 
 
 
2.11  AcraVision  
AcraVision displays the current rundown informat ion in an easy to read screen. If there is 
a failure in the tightening the Tor que/Angle is displayed in red.

TID Timeout:
 No Communication between the tool  and controller. This fault condition 
is usually caused by a problem in the tool  ID board. Try connecting another tool to the 
controller 
   Tool GND:  The tool ground loop is broken. This fault condition is usually caused by a 
problem in the controller or  tool. Try the tool and cable on another controller. The fault 
can be intermittent.  
   Power on Throttle:  The System thinks that the thro ttle is being activated or the run 
command through...

Locked rotor: The controller has not sensed hall 
transitions from the motor for a 
period of time. This is possible if the tool  is trying to achieve a high torque at a low 
speed. Increase the rundown speeds and make sure the tool is calibrated properly. It 
is also possible that the controller is f aulty. If the tool does not run at all try 
connecting it to a different controller.  
 
Drive Fault : The servo drive is not trying to  run the tool. Try the tool on another 
controller.
