High Speed Rundown
This tightening method is generally used as a fast pre-tightening stage. The torque transducer
integrated into the nutrunner measures the torque during the tightening. The value is processed
by the control system. When the defined Turnoff Torque is reached the nutrunner is shut off.
Thereafter the peak torque is measured during a dwell time and is then processed as the tighten-
ing torque of the bolt in the control system. This value is displayed on the Run Screen and can be
output to a printer or transmitted to other system components by data communication. When the
trigger torque is reached the torque curve is recorded and can be viewed and evaluated using
the oscilloscope function.
The following parameters are programmable from the Standard Application Builder:
• Fastening Sequence = 11
• Trigger Torque [Nm] = trigger torque, beginning of measurement for the graphic display
• Turnoff Torque (Nm) = turnoff torque for the pre-tightening stage.
• Speed = maximum speed of the nutrunner during the pre-tightening stage.
