2.10    Statistics  
The statistics page takes a collection of final torque samples from a rundown file then 
calculates and displays statistical information about the collection. In addition, a histogram is 
plotted, and the fi nal torque for each rundown is displayed  graphically. The maximum 
number of rundowns that can be evaluated is 2048. If more data is stored in the file, then 
data for only  first 2048  rundowns  are used.  Torque values are displayed in the units shown 
on the Main Window toolbar. Rundown Files are saved using Toolware with *.MS.csv 
extension. This file type can be generated in the Rundowns page by receiving rundown 
data, then saving the data to a type  *.MS.csv file. We can open this using the File - > Open 
option.

PSet Selection (Parameter Set):   
a.  Only rundowns with the PSet  selected are used in the collection. In addition, 
Only Rundowns with settings for Torque High Limit, Torque Low Limit, and 
Target that match the first rundown are used in the collection.  
b.  If 0 is selected for the  PSet, all rundowns in the file will be used  in the 
collection.

Stats: 
 POP:  Population; The total number of observations used to calculate the statistical data.  
  Mean:  (Sum of All Readings) / (Number of Readings)  
   CP:  Overall capability, which is the ratio of 6 sigma to the tolerance.  The equation for 
CP is:      (Torque High Limit  – Torque Low Limit) / 6 Sigma  
  CPK:  Process capability, which takes both sigma and mean into account.  The equation 
for CPK is the smaller of:  (Torque High Limit  – Mean) / 3 Sigma   or   (Mean  – Torque 
Low Limit) / 3 Sigma  
  6 Sigma:  The standard deviation multiplied by 6.  A total range of 6 sigma will include 
99.7% of all data.  The equation for six sigma is as follows:  
  6σ  = 6 X   
 
 
 
  Range:  The difference between the maximum and minimum reading.  
  Min Tq:  The maximum torque reading.  
  Max Tq:  The minimum torque reading.

Histogram of Final Torque Samples 
The histogram shows the frequency count of the number of times that a specified interval, or  
bin, occurs in the collection of final torque samples.  The range of the histogram is equally 
divided in to a specified number bins using the following equations:  
  The width   
  of the frequency bin is   
o   
o  Where:   
   m is the selected Number of Bins . 
   max is the upper ceiling for the torque range to be evaluated ( Range 
Ceiling ) 
   min is the lower floor for the torque range to be evaluated  ( Range 
Floor )  
  The  center points  of each bin are set according to the following equation:   
o   
 
For reference, the Parameter Set v alues for Torque Hi, Torque Low, and Torque Target 
are taken from the first rundown in the collection and plotted as horizontal lines.  
Histogram adjustment:   
The width, center point, and number of bins can be adjusted by selecting different 
values for Range Ceiling, Range Floor and the Number of Bins.  
  Number of Bins Selection:   The histogram initially uses the number of rundowns 
in the collection for the number of bins. If there are more than 200 rundowns, then 
the number of bins is set to 200. The number of bins can be adjusted from 2 to 
the number of rundowns + 1.   
  Range Ceiling Adjustment:  This value is initially set to the maximum torque 
sample rounded up to the next higher integer.  This can be adjusted in increments 
of 0.1  
  Range Floor Adjustment:  This value is initially set to the minimum torque 
sample rounded down to the next lower integer. This can be adjusted in 
increments of 0.1 
  Bin width and center points will be updated on a change to these values.

Final Torque Sample Graph 
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 Low, and Torque Target 
are taken from the first rundown in the collection and plotted as vertical lines.

3.2 Trouble Shooting 
Fault Description  
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 throttle is being activated or the run 
command through logic I/O is turned on. You can verify this by monitoring the tool 
buttons in toolware. Make sure that the throttle is completely returning home 
completely after being released.  
 
Button Timeout : The button signals from the tool are not being received by the 
controller in a certain amount of time. Try connecting another tool to the system.  
 
Button State : An illegal light ring state has occurred. Two or more direction halls are 
enabled. You can verify this by monitoring buttons using ToolWare. Try recalibrating 
the buttons using ToolWare (CW, C enter, and CCWorTrigger and MFB button  
Undefined Voltage : Either the controller voltage configuration or the tool voltage 
parameter are undefined. Try the tool on another system.   
 
Incompatible Voltage : The controller is not compatible with the tool.  
  Illegal tool: A tubenut tool is connected to a system setup for multiples.  
  Free Run Timeout : The tool has run for a period of time before seeing the threshold 
torque. The throttle must be released and pressed again before the tool will run 
again. This tim e is adjustable using ToolWare. The default value is 5 seconds.   
 
Load Run Timeout : The tool has run for a period of time after seeing the threshold 
torque. The throttle must be released and pressed again before the tool will run 
again. This time is adjustable using ToolWare. The default value is 15 seconds.  
    Hall Error: The motor hall  sensors (for commutation) have achieved an illegal state a 
specific number of times. If the tool does not run at all or the square drive has to be 
rotated before the tool will run the motor is probably damaged. Run this tool on a 
different controller to determine where the problem lies.   
 
Tool Offset : Based on the offset value of the transducer during re- zero and the tool 
cal value, the tool cannot mathematically reach the target torque. This problem can 
occur if the cal value has been drastically changed and the target torque in near the 
max torque of the tool. Try resetting the cal value to defaults and calibrating the tool 
using an approved rotary transducer.    
						

							 48 
Tool Level: The tool transducer output voltage has exceeded the maximum or 
minimum allowable value. Try the tool on another system.  
 
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 faulty. 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.   
 
PSet  Value : An illegal rundown parameter set has been sent to the controller. Try 
resetting the parameter sets back to  factory defaults.  
   
TID Parameter Value: The tool sent an illegal parameter to the controller. Try cycling 
power to the system. Also, try the tool on another system.   
 
TID Parameter Timeout : The tool did not respond to a requested parameter for a 
period of time. Try cycling power to the system.  Also, try the tool on another system.  
 
Target Value Fault : The target torque is set higher than the capacity of the tool.  
  No Direction Hall : The tool was told to start running either from the throttle or 
through logic I/O but it wasn’t told what direction to go. Use ToolWare to monitor the 
buttons. Make sure the wiring to the I/O is correct if running the tool remotely.  
  Xdcr Level : The tool transducer output voltage has exceeded the maximum or 
minimum allowable level.
