  • Page 13: Introduction

    2 Introduction 2.1 Intended use ® The DIGIFORCE 9307 is an instrument for monitoring repetitive production processes. Its core function is to record and analyze signals from processes in which physical variables, such as force, pressure or torque, vary as a function of displacement, angle or time according to a defined curve. The resultant measurement curve is analyzed using graphical evaluation elements such as windows, envelopes and thresholds.

  • Page 17: Equipment Design And Functions

    3 Equipment design and functions 3.1 Range of functions ® The DIGIFORCE 9307 monitors processes in which precisely defined functional relationships between two or more measured quantities need to be demonstrated. These measured quantities are recorded synchronously during the manufacturing process or subsequent functional testing to produce a measurement curve, which is then assessed using graphical and mathematical evaluation techniques.

  • Page 18: Expansion Levels

    3.1.1 Expansion levels ® The DIGIFORCE 9307 lets you store 32 or optionally 128 measurement programs, and to switch rapidly between them during the process. This means that you can simply change the measurement program when you change parts or when performing sequential sub-processes on one work piece. A measurement program contains the full set of parameters for the sensors, the measurement procedure and the evaluation of the measurement curve(s).

  • Page 19: Suitable Sensors

    3.2 Suitable sensors ® The DIGIFORCE 9307 is able to process signals from a vast range of sensor technologies. Note The physical connectors, and hence the sensors connected to these connectors, are assigned to the recorded curve variables (X/Y1/2 curve) in the "Channel settings" configuration menu. ®...

  • Page 20: Recording Measurement Curves

    Connection example: 3.3 Recording measurement curves An external control signal or an internal condition triggers the measurement. Immediately after ® receiving this active start condition, the DIGIFORCE 9307 starts to write to the data memory the ® values measured by the sensors as X/Y value pairs. The DIGIFORCE 9307 stops making these measurements when a stop condition is met.

  • Page 21: Sampling Methods For The Measurement Signals

    3.3.2 Sampling methods for the measurement signals ® The DIGIFORCE 9307 supports three different sampling methods, which you can also use in combination. In addition to time-based sampling, you can use a definable delta (Δ) X-value or delta (Δ) ® Y-value to record the pairs of curve values.

  • Page 22: Absolute Reference

    3.3.3.1 ABSOLUTE reference With the ABSOLUTE setting you are defining the X-axis reference of the measurement curve to be the zero point of the sensor connected to that channel. For sensors that provide relative measurements, such as incremental linear or rotary encoders, the origin of the X-axis can also be the start signal for the measurement.

  • Page 23: Final Force Reference

    3.3.3.2 FINAL FORCE reference ® With the FINAL FORCE reference, the DIGIFORCE 9307 delays the curve to after the measurement phase and references it to the last measurement point (final force). For a measurement curve with a ® forward and return section, the DIGIFORCE 9307 sets the turning point as the zero point when "final force"...

  • Page 24: Reference Line Reference (Overshoot/Undershoot)

    3.3.3.3 REFERENCE LINE reference (overshoot/undershoot) ® With the REFERENCE LINE reference, the DIGIFORCE 9307 delays the curve until after the measurement phase. It then references the curve to the point where the Y-value went above or below a configurable Y-level. If the final force of a pneumatic or hydraulic press varies, then using the final force as a reference would produce a spread in otherwise identical measurement curves.

  • Page 25: Trigger Reference (Overshoot/Undershoot)

    3.3.3.4 TRIGGER reference (overshoot/undershoot) Unlike the references ABSOLUTE, FINAL FORCE and REFERENCE LINE, with the TRIGGER reference, recording of measurements does not start until readings go above or below the configured ® threshold (e.g. force threshold). Then the DIGIFORCE 9307 writes the subsequent value pairs of the ®...

  • Page 26: Evaluation Methods

    3.4 Evaluation methods ® As a truly multi-purpose evaluation tool, the DIGIFORCE 9307 offers a wide selection of configurable evaluation elements. These can be used for OK/NOK classification of a vast range of curve types. In addition to traditional evaluation windows with defined entry and exit sides, you can also use thresholds, trapeziums of type X or Y and envelopes as graphical evaluation tools.

  • Page 27: Evaluation Windows

    3.4.1 Evaluation windows You can enable up to ten windows in one measurement program. You define the "Window evaluation element” by the corner points of a rectangle: X and Y . You can specify almost any criteria for how the measurement curve enters or exits the window. For instance, the block situation of a press-insertion process can be monitored using "Entry bottom"...

  • Page 28: Trapezium Window

    3.4.2 Trapezium window ® The DIGIFORCE 9307 classifies trapezium windows into two types: the X trapezium and the Y trapezium. The X trapezium uses fixed X limits, X and X ; the Y trapezium uses fixed Y limits, and Y You can enable up to four trapezium windows in one measurement program.

  • Page 29: Thresholds

    3.4.3 Thresholds The "Threshold" evaluation element can be used to calculate and monitor where the measurement curve passes through a defined X-value or Y-value. As user, you can choose between threshold type X or Y. You can enable up to four thresholds at once in one measurement program. Thresholds output an OK/NOK result after the measurement phase.

  • Page 30: Mathematical Functions

    3.4.5 Mathematical functions You can use the mathematical functions to perform up to ten basic operations (addition, subtraction, multiplication and division). These can be applied, for instance, to the results of the graphical ® evaluation elements. The DIGIFORCE 9307 can display the results of these functions as values in a measurement window.

  • Page 31: Rotary Switch Evaluation

    3.4.6 Rotary switch evaluation ® The DIGIFORCE 9307 can use the "Rotary switch evaluation" function to monitor periodic cycles between maxima and minima. These periodic variations arise, for instance, when measuring the torque and angle for rotary controls. To monitor such curves, in the rotary switch evaluation elements you can define up to two independent tolerance bands per measurement, each band containing up to 32 maxima and 32 minima respectively.

  • Page 32: Sensor Test

    3.6 Sensor Test Regular checking of sensors plays a crucial role in the test reliability of a quality control system. This is ® done by applying defined physical quantities to the sensors. The DIGIFORCE 9307 then evaluates the resultant electrical signals. To program the values for these checks, a feed unit, for example, moves into a reproducible position, ®...

  • Page 33: Visualization, Signaling And Transfer

    3.8 Visualization, signaling and transfer ® Immediately a measurement has finished the DIGIFORCE 9307 shifts into the evaluation phase. In this phase, it checks whether the measurement curve satisfies the conditions set by the evaluation elements such as windows and envelopes or by the mathematical functions. If this is the case, the ®...

    4.3 Grounding and shielding The DIGIFORCE 9307 is grounded via the PE conductor connected to the cooling unit (Class I appliance). All metal conducting parts are grounded in accordance with IEC60204 / EN60204. This grounding prevents dangerous voltages occurring on these parts in the event of unexpected and unnoticed insulation faults.
