Glossary
5
pulses per degree
number of encoder pulses generated by the tool when
rotating the head exactly 1 degree or 1/360 of a revolution
range (R)
a statistical measurement of the difference between the
lowest and highest reading taken in a sample
redundant transducer
secondary transducer used to read torque
redundant transducer calibra-
tion
the calibration process of the secondary transducer
reject interlock
the stopping of further operation of the system after a pre-
determined number of rejected cycles has occurred
rejected data
the data generated by unacceptable rundowns
rejected rundown
a rundown that has not met the criteria of a fastening
strategy
remote parameter select
a remote device that bypasses the parameter select but-
ton on your unit
reset after NOK (linking)
Determines whether the controller will reset to linking
position 1 after an NOK.
rundown printout
gives the control system direction for when to print
run number
number of accepted and rejected rundowns
second transducer
frequently referred to as the redundant transducer
sequence 11
high speed rundown
sequence 30
torque control/angle monitor
sequence 50
angle control/torque monitor
sequence 41
angle controlled backoff
speed
max speed of the nutrunner during the tightening stage
standard deviation (
σ
)
the measurement of the scatter of the population around
a mean
start delay time [ms]
time delay before the stage will start
start spike time [ms]
time delay for the control system to start measuring
torque after the stage starts
statistical data
data used to measure the performance and accuracy of
the unit and tool
status light
lights located either on the unit or tool that represent
accepted and rejected cycles
sub group size (Sub Sz)
the sub group size of data used for statistical analysis; the
smallest sub group size = 5
synchronization input
when active allows the tool to start from stage to stage in
conjunction with tool start
synchronization output
active at the end of each stage to signal a stage is com-
plete
threshold torque [Nm]
torque to begin counting angle
tightening group (linking)
Contains a specific linking strategy of up to 32 positions.
It is remotely selectable from the Application Inputs (0-2).
tool enable
when active allows the tool to start in conjunction with tool
start
