216/316 Bosch Rexroth AG | Tightening Technology 9 Tightening Processes9.2 Tightening program steps9.2.3.3 Additional functionsSpeed, start suppressionControl angleThe additional functions Speed and Start suppression for the extended tightening step must be parameterizedanalog to those for the standard tightening step (see page 213).The Control angle (see page 238) entry field is displayed if Yield point has been selected as a target ormonitoring function. The control angle is an important setting for tightening processes controlled by theyield point.The additional functions Trigger output and Options are also available in the extended tightening step(Fig. 9–11 and 9–12).Trigger outputFigure 9–11:Selection of the trigger outputThe trigger output is set, i.e. the TrigOut control signal changes to “High”, when the trigger condition isreached (start angle counting, step start, target function reached).NoteFurther information on the control signals (description, timing diagrams) can be found in chapter 6, “ControlSignals” on page 55!OptionsThis button calls up a window to enter the torque and angle value (absolute values) that are in the tighteningplan (or graph). They can be stored as a flag or memory aid in the Options/Graph values field (Fig.9–12).Figure 9–12:Entry field for absolute torque and angle value9.2.3.4 Torque thresholdsSelecting one of the two option fields (Fig. 9–13) determines whether the torque threshold should be determinedabsolute or relative to the previous tightening step.Figure 9–13:Torque thresholdsThe following applies to an absolute torque threshold:– Angle counting for the Angle target or monitoring function only begins once the torque threshold,which must be entered in the Angle entry field, has been reached (Fig. 9–13).– The gradient evaluation for the Gradient target or monitoring function only begins once the torquethreshold, which must be entered in the Gradient/Yield point entry field, has been reached(Fig. 9–13).– The yield point calculation for the Yield point target or monitoring function only begins once thetorque threshold, which must be entered in the Gradient/Yield point entry field, has been reached(Fig. 9–13).The relative option field must be selected if the torque threshold is to be determined relative to the previoustightening step (see page 217).If two target functions, i.e. Angle and Gradient or Angle and Yield point are set, the torque thresholdmust be set separately for both (with different values, if necessary).System 350 | 3 608 878 040/05.2008
