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 = max speed of the nutrunner during the pre-tightening stage.

Torque Control with Torque and Angle Monitoring
This tightening stage is normally preceded by a fast pre-tightening stage. The transducer inte-
grated into the nutrunner measures the torque and the resolver measures the angle during the
tightening. The values are processed by the control system. When the threshold torque is
reached the angle count starts. When the 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 together with the evaluation of the rundown in the control system. This
value is displayed on the Run Screen and can be output to a printer or transmitted to other sys-
tem 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 in the Standard Application Builder:
• Sequence input value = 30
• Trigger Torque (Nm) = trigger torque, beginning of measurement for the graphic display.
• Threshold Torque (Nm) = threshold torque, beginning of angle counting
• Turnoff Torque (Nm) = shut-off torque for the stage.
• Torque High Limit (Nm) = max torque, high limit for torque reached.
• Torque Low Limit (Nm) = min torque, low limit for torque reached.
• Angle High Limit (deg) = maximum angle, high limit for angle reached. The nutrunner will stop
if this value is exceeded
• Angle Low Limit (deg) = minimum angle, low limit for angle reached.
• Speed = max speed of the nutrunner during the tightening stage.
