Programming Advanced Application Builder The Advanced Application Builder allows the user to display all of the Application configurations at once, the I/O assignment for inputs and outputs, the configuration of a field bus interface, the configuration of fastening sequences (step counter) and changes in system settings that define monitoring of execution.
Programming Basic Application Builder Fig. 3-2: Torque Control/Angle Monitoring Fig. 3-3: Angle Control/ Torque Monitoring Basic.txtS The Basic Application Builder allows you to program a typical two-stage sequence. The first stage controls fastening at high speed, and the second controls final tightening at low speed with either torque or angle shut-off.
Programming 3.2.4 Advanced parameter default values Parameter name Stage 1 Stage 2 Start delay time [mS] Start spike time [mS] Max. fastening time [ms] 10000 10000 End delay time [mS] Torque Filter Factor If an Application with more than two stages is required, or if a different Fastening Strategy is to be selected for the Application than the one described above, you must use the Standard Applica- tion Builder.
Programming Standard Application Builder 3.3.1 Standard Application Builder / View Stages Fig. 3-5: View Stages viewstag.txtS From View Stages, you can program Stages 1-6 and a Backoff Stage for a given tool and applica- tion. When the tool is started, each Stage having a programmed Fastening Sequence will be run in succession based on the results from the previous stage.
Programming 3.3.2 Standard Application Builder / View Stages / Copy Fig. 3-6: Copying From the Standard Application Builder, the user can press the Copy <F2> softkey to copy the parameters for an Application or Stage to one or more other Applications or Stages.

Page 31
Programming Sequence 50 Angle Controlled Tightening with Angle and Torque Monitoring This tightening sequence is generally preceded by a fast pre-tightening cycle. The transducer integrated 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 Turnoff angle is reached the nutrunner is shut off.
Programming 3.3.4 Standard Application Builder / Parameters Fig. 3-8: Parameters paramete.txtS The parameters can be programmed for a certain tool, Application and Stage based on the selected fastening strategy; then, only the parameters required for the Sequence are displayed. The Next Stage <F2> key will increment to the next stage until it reaches the last stage with a selected Sequence.
Page 33
Programming Sequence 11 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.
Page 34
Programming Sequence 16 Depth sensor, Angle Control with Angle and Torque Monitoring This tightening method is generally used as a fast pre-tightening stage. During fastening, the depth sensor built in to the tool generates a signal at the preset insertion depth. This signal is processed by the control system.
Page 35
Programming Sequence 30 Torque Control with Torque and Angle Monitoring This tightening sequence is generally preceded by a fast pre-tightening cycle. The transducer integrated 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.
Page 36
Programming Sequence 50 Angle Controlled Tightening with Angle and Torque Monitoring This tightening sequence is generally preceded by a fast pre-tightening cycle. The transducer integrated 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 Turnoff angle is reached the nutrunner is shut off.
Page 37
Programming Sequence 41 Angle Controlled Back-off with Angle Monitoring This fastening sequence is generally used to loosen a bolt a specified number of degrees. The resolver integrated into the nutrunner measures the angle during the backoff. The value is pro- cessed by the control system.
Programming 3.3.5 Standard Application Builder / Advanced Parameters Fig. 3-9: Advanced parameters advparam.txtS The user can enter the Advanced Parameters using the Advanced <F3> Softkey from the Parameter screen. These parameters are identical regardless of the selected Fastening Sequence. The Next Stage <F2> key will increment to the next stage until it reaches the last stage with a selected Sequence.

Statistics Statistics Understanding Statistics Your unit provides a wide array of statistical and data reports (charts) for the control of manufac- turing processes. The following provides a description of the control chart for variables and an outline of the procedure for its use. Known as the -R chart (pronounced X-bar-R), the chart for variables can be used whenever a quality characteristic can be measured and expressed by a numerical value.
Statistics 5.1.2 The Normal Curve Most processes in statistical control have a fixed pattern of variation. The mathematical curve that describes this pattern is known as the normal curve (see a) Fig. 5-2:). The normal curve is symmetrical about the average. It is high in the middle and becomes smaller as the distance from the average increases.
Page 99
Statistics Designate the Sample Size It is usually desirable to keep the sample size small so that variation within the sample is at a minimum, but not so small that statistical validity is lost. The control chart described in this docu- ment is structured for a sample size of five units.
Page 100
Statistics Calculate Process Center Lines After data for 20 samples of five have been plotted, calculate the center lines for both the aver- age and range plottings. The center line for the average chart is known as the grand average ( ) and is the average of all of the sample averages.
Page 101
Statistics Sometimes a process takes time to stabilize after start-up. If the indication of special cause vari- ation occurs only in the first few samples, continue to take several more samples and recalculate the limits by omitting the special cause values. However, if the indications of special cause varia- tion occur other than at start-up, action should be taken to identify and correct the cause, and the process re-started.
Statistics Special cause variation may be indicated by one of the following situations: • A point outside a control limit. • A shift, with several consecutive points inside a control limit but on the same side of the center line. •...
