TERMINOLOGY
KDU/K-DUCER/control unit
: the KDU-NT control unit
KDS/screwdriver
: the transducerized screwdriving tool to be used with the KDU control
unit
Transducer
: electronic component installed inside the KDS screwdriver which measures
the torque in real time
Tightening
: the screwdriving cycle, from start (pressing of the lever or initiating remote
lever control), to finish (automatic motor stop or lever or remote lever control release,
whichever happens first)
Rundown
: the portion of the tightening cycle before reaching the seating point (the point
where the screw or bolt head touches the assembly)
Seating point
: the point of the tightening at which the head of the fastener touches the
assembly, marked by an increase in the torque rate (steeper torque-angle slope) and
marking the end of the rundown phase.
Torque
: rotational force
Closing torque
: the last torque value measured when the screwdriver motor stopped or
when the screwdriver lever or remote lever control was released.
Running torque
: the peak or average torque value encountered during the rundown phase,
before reaching the seating point.
Clamping torque
: the closing torque minus the running torque. This is, theoretically, the
only portion of the closing torque that generates a clamping force from the fastener.
Target torque
: the closing torque that the system will target (torque control mode only),
resulting in a “Screw OK” result if successful. In Running Torque – Compensate mode, the
system targets a
Clamping torque
equal to the target torque, instead of a closing torque.
Prevailing torque
: an optional phase of the tightening during which the applied torque is
allowed to reach the maximum torque achievable by the screwdriver.
Torque control mode
: a tightening where the screwdriver motor automatically stops upon
reaching the target torque
